Important: A rEFInd zip file, when uncompressed, creates a directory called refind-version, where version is the version number. This directory includes a subdirectory called refind that holds the boot loader, along with another that holds documentation, as well as miscellaneous files in refind-version itself. When I refer to "the refind directory" on this page, I mean the directory with that precise name, not the refind-version directory that is its parent.
+Don't be scared by the length of this page! Only portions of this page apply to any given user, and most people can install rEFInd from an RPM or Debian package in a matter of seconds or by using the refind-install script in minute or two.
+ +Once you've obtained a rEFInd binary file, as described on the preceding page, you must install it to your computer's EFI System Partition (ESP) (or conceivably to some other location). The details of how you do this depend on your OS and your computer (UEFI-based PC vs. Macintosh). The upcoming sections provide details. See the Contents sidebar to the left for links to specific installation procedures. For most Linux users, an RPM or Debian package is the best way to go. If your Linux system doesn't support these formats, though, or if you're running OS X, using the refind-install script can be a good way to go. If you're using Windows, you'll have to install manually.
+ + + +Once you've uncompressed a rEFInd binary zip file, you can copy the entire refind directory into your EFI System Partition's (ESP's) EFI directory on UEFI-based PCs, so that rEFInd resides in EFI/refind. If you've tried rEFInd using a CD-R image file, you can copy the files from the EFI/refind directory on the CD to create an equivalent directory on the ESP. To avoid confusion, though, you should delete the rEFInd binary file for the CPU type your computer does not use. To the best of my knowledge, all UEFI-based PCs use 64-bit CPUs, so you should keep the refind_x64.efi binary and delete the refind_ia32.efi binary. Most Intel-based Macs also have 64-bit EFI implementations, so you should do the same thing; but very early Intel-based Macs have 32-bit EFIs (and sometimes 32-bit CPUs), which require the refind_ia32.efi file. You can determine whether your Mac needs the x86-64 or IA32 build by typing the following command in a Mac Terminal window:
+ + + +Installing rEFInd Using an RPM or Debian Package File
+ + +I provide RPM and Debian package files for rEFInd; and starting with version 0.8.1, I'm maintaining an Ubuntu PPA for rEFInd. If you have a working RPM-based or Debian-based Linux installation that boots in EFI mode, using one of these files is likely to be the easiest way to install rEFInd: You need only download the file and issue an appropriate installation command. In some cases, double-clicking the package in your file manager will install it. If that doesn't work, a command like the following will install the RPM on an RPM-based system:
+ +# rpm -Uvh refind-0.10.4-1.x86_64.rpm+ +
On a Debian-based system, the equivalent command is:
+ +# dpkg -i refind_0.10.4-1_amd64.deb+ + + +
Either command produces output similar to that described for using the refind-install script, so you can check it for error messages and other signs of trouble. The package file installs rEFInd and registers it with the EFI to be the default boot loader. The script that runs as part of the installation process tries to determine if you're using Secure Boot, and if so it will try to configure rEFInd to launch using shim; however, this won't work correctly on all systems. Ubuntu 12.10 users who are booting with Secure Boot active should be wary, since the resulting installation will probably try to use Ubuntu's version of shim, which won't work correctly with rEFInd. The shim program provided with more recent versions of Ubuntu should work correctly.
+ + +If you're using Ubuntu, you should be able to install the PPA as follows:
+ +$ sudo apt-add-repository ppa:rodsmith/refind +$ sudo apt-get update +$ sudo apt-get install refind+ + + +
The PPA version asks if you want to install rEFInd to your ESP. (Chances are you want to respond affirmatively.) The PPA version will update automatically with your other software, which you might or might not want to have happen. It's also built with GNU-EFI rather than with TianoCore. This last detail should have no practical effects, but it might be important if you've got a buggy EFI or if there's some undiscovered rEFInd bug that interacts with the build environment.
+ +Since version 0.6.3, the installation script makes an attempt to install rEFInd in a bootable way even if you run the script from a BIOS-mode boot, and therefore the RPM and Debian packages do the same. I cannot guarantee that this will work, though, and even if it does, some of the tricks that refind-install uses might not persist for long. You might therefore want to use mvrefind to move your rEFInd installation to another name after you boot Linux for the first time from rEFInd.
+ +Since version 0.6.2-2, my package files have installed the rEFInd binaries to /usr/share/refind-version, the documentation to /usr/share/doc/refind-version, and a few miscellaneous files elsewhere. (The PPA package omits the version number from the file paths.) Upon installation, the package runs the refind-install script to copy the files to the ESP. This enables you to re-install rEFInd after the fact by running refind-install, should some other tool or OS wipe the ESP or should the installation go awry. In such cases you can use refind-install or install manually.
+ + +Installing rEFInd Using refind-install under Linux or Mac OS X
+ + + +If you're using Linux or Mac OS X, the easiest way to install rEFInd is to use the refind-install script. This script automatically copies rEFInd's files to your ESP or other target location and makes changes to your firmware's NVRAM settings so that rEFInd will start the next time you boot. If you've booted to OS X or in non-Secure-Boot EFI mode to Linux on a UEFI-based PC, refind-install will probably do the right thing, so you can get by with the quick instructions. If your setup is unusual, if your computer uses Secure Boot, or if you want to create a USB flash drive with rEFInd on it, you should read the man page for this utility.
+ + + +By default, the refind-install script installs rEFInd to your disk's ESP. Under Mac OS X, you can instead install rEFInd to your current OS X boot partition by passing the script the --notesp option, or to a non-boot HFS+ partition by using the --ownhfs devicefile option. Under either OS, you can install to something other than the currently-running OS by using the --root /mountpoint option. (See Table 1 for details.)
+ +Under Linux, refind-install will be most reliable if your ESP is already mounted at /boot or /boot/efi, as described in more detail in the Installing rEFInd Manually Using Linux section. (If you installed Linux in EFI mode, chances are your ESP is properly mounted.) If your ESP is not so mounted, refind-install will attempt to locate and mount an ESP, but this action is not guaranteed to work correctly. If you run refind-install from a BIOS/legacy-mode boot, particularly on a computer that also runs Windows, you should be aware that the tricks the script uses to install itself from BIOS mode are rather delicate. You can convert to a more conventional configuration using the mvrefind script after you've booted in EFI mode.
+ +Prior to version 0.8.4, refind-install installed rEFInd to the OS X root partition by default. I changed this because the default configuration for OS X 10.10 ("Yosemite") makes this placement unusable. Instead, refind-install now installs to the ESP under OS X, just as it does under Linux. If you're upgrading a working install of rEFInd to the OS X root partition, it's best to pass the --notesp option to refind-install. This option is described in more detail shortly.
+ +A sample run under Linux looks something like this:
-$ ioreg -l -p IODeviceTree | grep firmware-abi -+# ./refind-install +Installing rEFInd on Linux.... +ESP was found at /boot/efi using vfat +Installing driver for ext4 (ext4_x64.efi) +Copied rEFInd binary files + +Copying sample configuration file as refind.conf; edit this file to configure +rEFInd. + + +Installation has completed successfully. + +
The output under OS X is a bit different:
+ ++$ ./refind-install +Not running as root; attempting to elevate privileges via sudo.... +Password: +Installing rEFInd on OS X.... +Installing rEFInd to the partition mounted at /Volumes/ESP +Found suspected Linux partition(s); installing ext4fs driver. +Installing driver for ext4 (ext4_ia32.efi) +Copied rEFInd binary files + +Copying sample configuration file as refind.conf; edit this file to configure +rEFInd. + +Installation has completed successfully. --The result should read either EFI32 or EFI64, indicating that you should use the refind_ia32.efi or refind_x64.efi binary, respectively.
+Unmounting install dir
Of course, before you can install the files, you must be able to access the ESP. The details of this task vary from one OS to another. If you have a choice, I recommend using Linux for rEFInd installation on UEFI PCs and OS X on Macs. (On Macs, you can optionally use OS X's main partition rather than the ESP for this purpose.) Windows provides relatively primitive tools for accessing the ESP and manipulating the EFI's boot list. I also describe some options for naming rEFInd that may be useful on some systems. Finally, I describe how to install some extra tools that you may find useful but that are not included with rEFInd.
+In either case, the details of the output differ depending on your existing configuration and how you ran the program. Unless you see an obvious warning or error, you shouldn't be concerned about minor deviations from these examples. If you run into such a situation, or if you want to install in an unusual way, read on....
+ +Note that the change to an ESP location for rEFInd with version 0.8.4 means that, if you upgrade rEFInd from an earlier version, you may notice a rEFInd boot option in the rEFInd menu. This option will boot the old version of rEFInd (or the new one, if something went wrong and the old version continues to boot). You can rid yourself of the unwanted boot menu by deleting the old files or by using dont_scan_dirs or dont_scan_files in refind.conf. Before you do this, you should use rEFInd to identify the unwanted files—the filename and volume identifier appear under the icons when you highlight the option. You can then locate and delete them from within OS X. Before you delete the old files, though, you may want to copy over any changes you've made to the rEFInd configuration, icons, and other support files.
+ +The refind-install script supports a number of options that can affect how it operates. For information on these options, consult the script's man page: Type man refind-install if you installed rEFInd via an RPM or Debian package; or read it in HTML form.
+ + +Installing rEFInd Manually
+ + +Sometimes the refind-install script just won't do the job, or you may need to install using an OS that it doesn't support, such as Windows. In these cases, you'll have to install rEFInd the old-fashioned way, using file-copying commands and utilities to add the program to your EFI's boot loader list. I describe how to do this with Linux, OS X, Windows, and the EFI shell.

- On a UEFI-based PC, under any OS, you should be able to replace your + old rEFInd file with the new one. Make sure that the new rEFInd has the + same name as the old one, and that it's for the correct CPU type. Since + UEFI launches boot programs by filename, a simple file replacement will + suffice to launch the new version. If the new version includes new + icons, you may want to copy some or all of them. + +
- On a Mac, you can copy over the old rEFInd binary file from + Linux and it will usually work, provided you copy directly + over the old file (rather than rename or delete the old file and then + copy the new one in its place). The same caveats about icons as apply + to UEFI-based PCs apply in this case. This method requires an extra + step in Mac OS X, though.... + +
- In OS X, if you copy over the original file with the new one, you'll + probably have to re-bless it to make it work. + +
- Under Linux or OS X, you can re-run the refind-install script. In + most cases this works fine, but you'll end up with a duplicate of the + icons directory (icons-backup, which holds the original icons, + whereas icons holds the icons from the new package). Normally + this just wastes some disk space; but if you've customized your icons, + you'll need to copy your altered icons back. Under Linux, versions + 0.6.2 and later of refind-install search for rEFInd in several + locations on the ESP, and will upgrade whatever is found. The same is + true with versions 0.8.5 and later under OS X when installing to the + ESP. If you install to a location other than the ESP under OS X, be + sure to include the same option to refind-install + (--notesp or --ownhfs) to replace the original rather + than create a new installation to the ESP. + +
- Under an RPM- or Debian-based Linux distribution, you can use your + package system to install a newer version of the RPM or Debian package + that I provide. This will upgrade the files in your Linux filesystem + and re-run the refind-install script, so as with the previous + options, you'll waste a little disk space on duplicated icons, but the + process should otherwise work quite well. + +
- If you installed using my Ubuntu PPA or a package provided by an OS + distribution (such as the packages that ship with Arch and ALT Linux), + performing a system update will probably update rEFInd, too. Depending + on how the package was created, though, this update might or might not + install the update to the ESP; you might need to manually re-run the + installation script. Consult your distribution's documentation for + details. My Ubuntu PPA will automatically run refind-install after + the package is installed if you selected the option to install + to the ESP; if you opted to skip this step, my PPA version will + continue to do so at every update, leaving you to manually update the + copy on the ESP.

- Memtest86—This + is a popular tool for performing basic hardware tests, and especially + memory tests. rEFInd recognizes this program when it is stored in the + EFI/tools, EFI/tools/memtest, + EFI/tools/memtest86, EFI/memtest, or + EFI/memtest86 directory, with a program filename of + memtest86.efi, memtest86_x64.efi, + memtest86x64.efi, or bootx64.efi. (Change + x64 to ia32 on IA-32 systems.) Be sure to download + the EFI version of the program. If you get the USB flash drive version, + you should mount the flash drive's ESP (partition 2) and copy the + EFI/BOOT directory to your own ESP's + EFI/tools/memtest or other Memtest86 directory name, as just + specified. rEFInd should then recognize it, provided the + showtools line includes the memtest or + memtest86 token. + +

You can obtain the file + from the original rEFIt + package, or beginning with rEFInd 0.6.9, an updated version is + included in the rEFInd package. The rEFInd version of gptsync_arch.efi uses a more sophisticated algorithm + for determining what GPT partitions to duplicate in the MBR and it + includes additional safeguards to minimize the risk of damage should + you run the program on a disk that might have been damaged. The + original rEFIt version of the program usually goes by the filename + gptsync.efi, whereas the updated rEFInd version ships with an + architecture code, as in gptsync_x64.efi or + gptsync_ia32.efi. The rEFInd refind-install script + installs gptsync_arch.efi when run + under OS X, but not when run on Linux. In addition to installing the + program, you must edit refind.conf, uncomment the + showtools line, and add gptsync to its list of + options. + +
- Drivers—You can install drivers to extend the capabilities + of the EFI. rEFInd ships with filesystem drivers for ext2fs, ext4fs, and + ReiserFS, which can enable you to boot a Linux kernel with EFI stub + support from an ext2fs, ext3fs, ext4fs, or ReiserFS partition. (rEFInd also + provides ISO-9660 and HFS+ drivers.) You can find additional drivers + from other sources, although they're still on the scarce side. See the + Using EFI Drivers page for more on this + topic. + +
- Secure Boot files—If you're running on a system that + supports Secure Boot, chances are you'll need extra support files, such + as shim.efi and MokManager.efi. I describe these in + detail on the Managing Secure Boot + page. + +
- iPXE—This tool provides the + ability to boot a computer from a network server. Consult the + BUILDING.txt file in the rEFInd source code package for + information on building and installing these tools. You must also + activate rEFInd's support by adding the netboot option to the + scanfor and/or showtools lines in + refind.conf. Network-boot/iPXE support is currently + experimental; I recommend that only developers or those who are + willing to use "bleeding-edge" software try it. Once activated, rEFInd + will present a new menu item for booting from the network server. + rEFInd itself will normally be installed locally. (You can deliver + rEFInd as a network-boot image, but that image will be able to boot + only OSes on the local disk.)
- Boot into Linux. + +
- Type efibootmgr as root to obtain a list of your boot loader entries. Each entry includes a boot number, as in Boot0003 or Boot0027. + +
- Remove all of the boot loader entries except rEFInd's by using efibootmgr's -b bootnum option to specify the boot entry and -B to delete it. For instance, typing efibootmgr -b 0027 -B as root deletes boot entry Boot0027. Issue a separate efibootmgr command for each boot entry. + +
- Re-install rEFInd using the install script. It's unclear from the original post if this meant installing from Linux or from OS X. + +
- Install rEFInd to an HFS+ volume using the --ownhfs option to refind-install. Unfortunately, this solution requires either creating a small HFS+ volume for rEFInd or using an already-existing non-bootable HFS+ volume (if you've got one for data storage, for example). + +
- Type sudo pmset -a autopoweroff 0 in a Terminal window. This solution is likely to work if sleep operations work normally up to a point, but fail after about three hours. + +
- A malfunctioning BIOS/legacy boot—If you installed Linux in BIOS/legacy mode, as most online documentation suggests, it could be that your hybrid MBR is missing or damaged. The usual symptom of this problem is that rEFInd shows a generic Linux penguin icon and that selecting it produces a message to the effect that a bootable OS could not be found. As hybrid MBRs are ugly and dangerous, I recommend avoiding them if possible, so my preferred solution to this problem is to set up EFI filesystem drivers and boot that way; however, fixing the hybrid MBR may be an easier solution. This is especially true if you installed a 32-bit version of Linux on a 64-bit Mac (or a 64-bit version on a rare Mac with a 64-bit CPU but a 32-bit EFI). + +
- EFI filesystem driver problems—Ideally, rEFInd should be able to load and run your Linux kernel directly, but this approach normally requires you to have a working EFI driver for the filesystem that holds your Linux kernel. This won't always be the case; and even if it is installed, there can be interference from other drivers, so you may need to remove the drivers that you don't use. If drivers are the root of your problem, you won't see any Linux options, or you'll see the one penguin icon (as above) with no others that point to your Linux kernel(s). + +
- Boot from an emergency Windows recovery disk. If you don't have one, you can prepare one from a working Windows system as described here. + +

- In diskpart, type sel disk 0 followed by list vol. You should see a set of partitions. This step is intended to help you identify your ESP, which will probably be the only FAT32 partition on the disk. (If you have multiple disks, you may need to try again with sel disk 1 or higher.) Note the volume number of your ESP. + +
- Type sel vol 1, changing 1 to whatever the ESP's volume number is. + +
- Type assign letter=S: to assign the ESP a Windows disk identifier of S:. (You can use another letter if you prefer.) + +
- Type exit to exit from diskutil. + +
- Type cd /d s:\EFI\Microsoft\Boot\ to change into the Windows boot loader directory. (If this directory doesn't exist, you may need to create it first with mkdir. If rEFInd or some other boot loader occupies this directory, back it up first. + +
- Type bootrec /fixboot. + +
- Type bcdboot c:\Windows /s s: /f ALL. Note that this command should set the Windows boot loader as the default. Omit /f ALL if you don't want to adjust the EFI's default boot program. + +
- Reboot and hope it works! If the computer boots straight to Windows and you want to use rEFInd, use bcdedit in Windows, as described in step 9 of the Installing rEFInd Manually Using Windows section of this page. + +
- You must first determine where rEFInd is installed. This can be any of
+ several locations:
+
+
-
+
+
- If you installed rEFInd 0.8.3 or earlier with the default options, + or if you used the --notesp option with rEFInd 0.8.4 or + later, it will be /EFI/refind on your main partition + +
- If you installed rEFInd 0.8.4 or later with the default options, or + if you used the --esp option with rEFInd 0.8.3 or earlier, + it will be in EFI/refind or EFI/BOOT on the + ESP. + +
- If you used the --ownhfs option to refind-install, + rEFInd will be in the System/Library/CoreServices + directory on the volume you specified. + +
- If you installed rEFInd manually, it will be wherever you put + it. + +
- In all cases, there could be duplicate (inactive) rEFInd files in + unexpected places. This is particularly true if you tried + installing rEFInd multiple times, each with different options to + refind-install. Thus, if you delete rEFInd and it still comes + up, you may have deleted the wrong files. (Note that dragging files + to the Trash may have no effect, though—at least, not until + you empty the Trash.) + +
- If necessary, mount the ESP or rEFInd-specific HFS+ volume, as + described in Installing rEFInd Manually Using Mac OS + X. (The mountesp script that comes with rEFInd will handle + this task.) + +
- Verify that rEFInd is installed in the directory noted in step #1. If a + refind.conf file is present, rEFInd is almost certainly + installed in that directory. If not, it's not rEFInd there and you + should not proceed. Be extra cautious about deleting the + System/Library/CoreServices directory, since that's + the default location of the OS X boot loader! Never delete this + directory from your OS X root (/) partition, only from the + partition you specified to refind-install using the + --ownhfs option. + +
- Once you've identified the rEFInd directory, delete it, or at least the + rEFInd boot file. This file may be called refind_x64.efi, + bootx64.efi, boot.efi, or conceivably something else. + You may need to use sudo rm at the command line to accomplish + this task, as in sudo rm -r + /Volumes/ESP/EFI/refind. + +
On some systems, efibootmgr won't do what you expect. On such systems, you may have better luck renaming the rEFInd files, as described in the Alternative Naming Options section.
-Installing rEFInd Using Mac OS X
+Installing rEFInd Manually Using Mac OS X
- +Before installing rEFInd on a Mac, you must determine whether it uses a 32-bit or 64-bit EFI implementation. Most Intel-based Macs have 64-bit EFIs, so you should use the refind_x64.efi file with them; but very early Intel-based Macs have 32-bit EFIs (and sometimes 32-bit CPUs), which require the refind_ia32.efi file. You can determine whether your Mac needs the x86-64 or IA32 build by typing the following command in a Mac Terminal window:
-The procedure for installing rEFInd on a Mac is similar to that for installing it under Linux, except that you can install it to the OS X's system directory rather than to the ESP, and you must use the bless utility rather than efibootmgr. To be precise, you should follow these steps:
- --
-
-
+$ ioreg -l -p IODeviceTree | grep firmware-abi +-
The result should include either EFI32 or EFI64, indicating that you should use the refind_ia32.efi or refind_x64.efi binary, respectively.
-You should also be aware of your OS X version and installation options. If you used whole-disk encryption (WDE) or a logical volume for installation, you cannot install to the OS X root partition; you must install to the ESP or to a separate HFS+ partition. WDE became an option with OS X 10.7 and logical volumes are the default in OS X 10.10. If in doubt, proceed with an installation to the ESP or to a separate HFS+ partition.
-The procedure for installing rEFInd on a Mac is similar to that for installing it under Linux, except that you must use the bless utility rather than efibootmgr to register the program with the firmware. Also, you'll probably have to mount your ESP manually, since that's not done by default under OS X. To be precise, you should follow these steps:

When you reboot, your Mac should bring up the rEFInd menu, and should continue to do so thereafter. If you make changes that break this association, you can re-run the bless command (if necessary, restoring the rEFInd files first). This might be necessary after installing system updates from Apple.

If you make changes that break this association, you can re-run the bless command (if necessary, restoring the rEFInd files first). This might be necessary after installing system updates from Apple or if you upgrade rEFInd to a newer version.
-If you're replacing rEFIt, you may discover that rEFInd works on the first boot, but the system reverts back to rEFIt or a direct boot to OS X on the second boot. To fix this problem, you can remove the rEFItBlesser program, which is located at /Library/StartupItems/rEFItBlesser. This program attempts to keep rEFIt set as the default boot loader, but it also has the purpose of protecting the computer from launching the wrong OS after waking from sleep. If you want that protection, my suggestion is to install rEFIt and rEFItBlesser and then replace the refit.efi file with refind_x64.efi or refind_ia32.efi (renaming it to refit.efi. Used in this way, rEFInd will still look for its own configuration file, refind.conf, so you'll need to move it but not rename it. If you don't move the icons from the rEFInd package, your icons will continue to look like rEFIt icons, and you'll be missing the new icons for specific Linux distributions that rEFInd provides.

One final caveat: It's conceivable that rEFItBlesser is what's causing filesystem corruption for some users, so if you've been having this problem with rEFIt, it might be worth disabling this program and not using it with rEFInd.
If you want to remove rEFInd from your system, you can delete its files. The Mac will revert to booting using whatever standard boot loader it can find. Alternatively, you can use bless to bless another EFI boot loader. The GUI Startup Disk utility in System Preferences provides a simplified interface that enables you to select which OS X installation to boot, but it doesn't look for non-Apple boot loaders, so you can't use it to enable rEFInd.

Unfortunately, I know of no Windows tool that's equivalent to efibootmgr under Linux or bless under OS X. (Such a tool must exist, but I don't know what it is. If you do, please e-mail me a pointer!) This can make adding rEFInd to your system a bit tricky, particularly if your firmware provides few boot options. In the best of all possible worlds, you'll be able to use your firmware's user interface to add rEFInd to your firmware's own boot manager; however, far too many EFI implementations lack even this modest capability.

Installing rEFInd Manually Using an EFI Shell
+ + + + +If you can't currently boot any OS (say, because a firmware update has wiped your NVRAM entries), you may find it convenient to install rEFInd using an EFI version 2 shell. Unfortunately, the bcfg command described here is not available in the EFI version 1 shell, and the version 2 shell is unusable on many firmware implementations prior to 2.3.1. Thus, this procedure won't work for all systems.
+ +In addition to emergency situations, using bcfg can be desirable if efibootmgr or other OS-hosted tools don't do the job. This happens under VirtualBox, for instance. An alternative in such cases can be to use alternative names for rEFInd.
+ +To begin, you must have a way to launch your shell. Unfortunately, this can pose a dilemma, since without rEFInd or some other boot manager, many EFI implementations lack the means to launch a shell. Some will do so, though, if the shell is stored as shellx64.efi (for x86-64) or shellia32.efi (for x86) in the root directory of the ESP. Thus, you can try copying your shell file there. You can obtain EFI 2 shells here:
+ +-
+
+
Note that the IA32 shell included in rEFInd's CD-R image version is a version 1 shell, so you can't use it for this purpose. You can, however, copy rEFInd's files from the CD-R. You can even launch the version 1 shell included with rEFInd and then use that to launch a version 2 shell. The x86-64 shell on the CD-R is the alternate shell, which should work on any x86-64 computer. Once you've booted the shell, you can proceed as follows:
+ +-
+
+
With any luck, rEFInd will start up at this point. If not, you can check your settings using a shell or an emergency system for your OS of choice. In an EFI shell, you might type bcfg boot dump -b to view your boot loader entries and verify that rEFInd appears at the top of the list. Be sure to check the pathname for typos. If you continue to have problems, you might look into giving rEFInd a fallback filename that your firmware will recognize.
+Alternative Naming Options
-Some EFI implementations do a poor job of honoring the boot options set via Linux's efibootmgr or other tools. You may also lack access to such utilities, such as if you must install rEFInd in Windows. In such cases, you may need to change the boot loader's name so that the EFI will see it as the default boot loader. rEFInd should then boot when your NVRAM lacks information on specific boot loaders to use. To do this, follow these steps:

In such cases, you may need to change the boot loader's name so that the EFI will see it as the default boot loader. rEFInd should then boot when your NVRAM lacks information on specific boot loaders to use. Broadly speaking, there are two alternative names that are most useful:
+ +-
+
+
If you need to use one of these names, or something more exotic, you can do so in either of two ways: You can use the mvrefind script to move your installation in one step, or you can move and rename your files manually.
+ + +Using mvrefind
+ + +The easiest way to move a rEFInd installation, at least in Linux, is to use the mvrefind script. If you installed from one of my RPM or Debian packages, this script should be installed in /usr/sbin, so you can use it like a regular Linux command; otherwise you'll need to install it to your path yourself or type its complete path. Either way, it works much like the Linux mv command, but you pass it the directory in which a rEFInd installation appears and a target location:
+ ++# mvrefind /boot/efi/EFI/BOOT /boot/efi/EFI/refind ++ +
This example moves rEFInd from /boot/efi/EFI/BOOT to /boot/efi/EFI/refind. It differs from mv in several ways: + +
-
+
+
The mvrefind script is likely to be useful in resolving boot problems—if your system won't boot, you can try copying the installation to /boot/efi/EFI/BOOT, /boot/efi/EFI/Microsoft/Boot, and /boot/efi/EFI/refind in turn, testing the boot process after each attempt. (These filenames all assume your ESP is mounted at /boot/efi.) You could also copy a BIOS-mode install from /boot/efi/EFI/BOOT or /boot/efi/EFI/Microsoft/Boot to /boot/efi/EFI/refind to make it more robust against Windows repairs (assuming your firmware isn't broken).
+ + +Renaming Files Manually
+ + +You can move and rename rEFInd manually from any OS by following these steps:
-
-
When you reboot, rEFInd should come up. With any luck, it will detect your old boot loader as an option, if one was installed before.
+ +Upgrading rEFInd
+ + +If you've installed an earlier version of rEFInd, you can upgrade a bit more easily than you can install directly:
+ +-
+
+
In all cases, if the new version includes new or altered configuration file options, you may need to manually update your configuration file. Alternatively, if you've used the default configuration file, you can replace your working refind.conf with refind.conf-sample from the rEFInd zip file. (When using refind-install, this file will be copied to rEFInd's installation directory under its original name, so you can rename it within that directory to replace the old file.)
+ +If you're upgrading to rEFInd from rEFIt, you can simply run the refind-install script as described earlier or perform a manual installation. Once installed, rEFInd will take over boot manager duties. You'll still be able to launch rEFIt from rEFInd; a rEFIt icon will appear in rEFInd's menu. You can eliminate this option by removing the rEFIt files, which normally reside in /EFI/refit.

-rEFInd includes the ability to launch any EFI program; however, rEFInd detects only certain programs. These include boot loaders in traditional locations and a handful of other programs. To launch these other programs, you must download and install them separately from rEFInd:

I have found several possible solutions, though: Using the --shortform option, using the fallback filename, moving rEFInd to an HFS+ volume, clearing NVRAM entries, fixing wake problems, and fixing a failure to find Linux.
+ + +Using the --shortform Option
+ + +Prior to version 0.8.5, these instructions and the refind-install script omitted the --shortform option from the bless command when installing rEFInd to the ESP. A rEFInd user, however, discovered that using the option eliminated the 30-second delay, so it is now the default with 0.8.5's refind-install, and is specified in the instructions. If you installed rEFInd 0.8.4 or earlier, you may want to re-install or re-bless rEFInd using this option.
+ +There is one caveat, though: The man page for bless notes that --shortform notes that its use can come "at the expense of boot time performance." Thus, it's not clear to me that this option might not actually create problems on some computers. (It's eliminated the boot delay on my 2014 MacBook Air and has no detrimental effect on an old 32-bit Mac Mini that's never had a boot delay problem, though.) Thus, if you have problems with rEFInd 0.8.5 or later, you might try running bless, as described in Installing rEFInd Manually Using OS X's step 8, but omit the --shortform option.
+ + +Using the Fallback Filename
+ + +I've received a few reports that installing rEFInd to the ESP using the fallback filename (EFI/BOOT/bootx64.efi on most systems, or EFI/BOOT/bootia32.efi on very old Macs) can work around a sluggish boot problem. In fact, version 0.8.4's refind-install script copied the rEFInd binary to this name when run under OS X. (Version 0.8.5 switches to using --shortform with the more conventional EFI/refind/refind_x64.efi or EFI/refind/refind_ia32.efi name, as just noted.) If you installed to a name other than EFI/BOOT/BOOT{ARCH}, either manually or by using the 0.8.5 or later refind-install, renaming (and re-blessing) the installation is worth trying.
+ + +Moving rEFInd to an HFS+ Volume
+ + +Most of the reports of sluggish Macintosh boots I've seen note that the user installed rEFInd to the ESP rather than to the OS X root partition. Some users have reported that re-installing rEFInd to the OS X root partition clears up the problem. This is obviously a straightforward solution to the problem, if it works. (This location is not an option when using WDE or OS X logical volumes.) Note that rEFInd can launch boot loaders that are stored on any partition that the EFI can read no matter where it's installed; therefore, you'll still be able to launch boot loaders stored on the ESP (or elsewhere) if you install it in this way.
+ +A variant of this solution is to create a small (~100MiB) HFS+ volume to be used exclusively by rEFInd. You can then install rEFInd to that volume with the --ownhfs option to refind-install, as in ./refind-install --ownhfs /dev/disk0s6 if the volume is /dev/disk0s6. This approach has the advantage that it can be managed via OS X's own Startup Disk tool in System Preferences.
+ +The biggest drawback to storing rEFInd on an HFS+ volume is that you won't be able to edit the rEFInd configuration file or move rEFInd-related binaries from an EFI shell if you install it in this way, since Apple's HFS+ driver for EFI is read-only. (The same is true of rEFInd's HFS+ driver, so it won't help you overcome this limitation.) You may also be limited in making changes to your rEFInd configuration from Linux or other OSes, too, since Linux's HFS+ drivers disable write support by default on volumes with an active journal. You can force write access by using the force option to mount; however, this procedure is noted as being risky in the Linux HFS+ documentation, so I don't recommend doing this on a regular basis on the OS X boot volume. This isn't as risky if you use a dedicated HFS+ rEFInd partition, though. You could even mount it as the Linux /boot partition, in which case it would also hold the Linux kernel and related files.
+ +A variant of this solution is suggested in this blog post, which recommends placing rEFInd on an HFS+ volume on the first SATA channel. (In the blogger's case, that channel used to hold an optical drive, but that drive was replaced by a hard disk.)
+ + +Clearing the NVRAM Entries
+ + +Another possible solution is documented in a Web forum post. Be aware, though, that this procedure involves using the efibootmgr utility on Macs, which has been known to damage the firmware on some Macs. Other reports indicate that this problem has been fixed with 3.3.0 and later kernels. Thus, I present this information cautiously and with a strong "use at your own risk" warning. If you care to proceed, I recommend you update your Linux kernel to the latest possible version and then proceed as follows:

+
+
Fixing Wake Problems
+ + +Some people have reported that installing rEFInd causes problems with resuming from a suspended OS X session. I know of two workarounds to such problems:
+ +-
+
+
I've recently acquired a 2014 MacBook Air, but I haven't yet had the chance to try to reproduce this problem and find a workaround. It's on my to-do list, though.
+ + +Fixing a Failure to Find Linux
+ + +Some users report that rEFInd doesn't detect Linux, or won't boot it when it is found. Broadly speaking, there are two common causes of this problem:
+ +-
+
+
If you suspect that your hybrid MBR is damaged, you can try re-creating it with my GPT fdisk (gdisk) program. The GPT fdisk hybrid MBR documentation covers this procedure in detail. You can run gdisk from either OS X or Linux, although you may need to install it, particularly in OS X.
+ +If you suspect driver problems, you'll need to mount your ESP (as described in the manual OS X installation instructions), locate the rEFInd drivers_x64 directory, and adjust its contents. Make sure you have a driver for the filesystem that holds your Linux kernel. If you don't know what filesystem this is, it's probably ext4fs. rEFInd ships with several filesystem drivers, including one for ext4fs. You should also remove unnecessary filesystem drivers. I've seen several reports of one driver interfering with others' operation. The biggest culprit seems to be the HFS+ driver when used on Macs.
+ + + + +Fixing Windows Boot Problems
+ + +Most Windows boot problems are best addressed on Windows-specific sites, so I recommend you make the rounds of Windows forums to solve such problems. There is one that deserves mention here, though: If you accidentally erase the Windows boot loader file, EFI/Microsoft/Boot/bootmgfw.efi, you won't be able to boot Windows. The simplest solution is to restore this file from a backup you prepared ahead of time. If you don't have such a backup, though, you can restore it as follows:

+ + +Uninstalling rEFInd
+ + +If you decide you don't want to keep rEFInd, you can uninstall it. Doing so is a matter of removing the rEFInd files from your ESP (or from your OS X boot partition, if you installed the program there). The exact details of how to do this vary from one OS to another, though; and in some cases there are alternatives to completely uninstalling rEFInd that are easier to implement.
+ + +Uninstalling rEFInd from Linux
+ + +In Linux, a command like the following, typed as root, should remove rEFInd:
+ ++# rm -r /boot/efi/EFI/refind ++ +
You must type this command as root (or use sudo in some environments, such as under Ubuntu). This example assumes that your ESP is mounted at /boot/efi and that rEFInd is installed in EFI/refind on that partition. If you've mounted your ESP elsewhere, or installed rEFInd elsewhere, you should adjust the command appropriately.
+ +If you installed via an RPM or Debian package in Linux, using your package manager will remove the package files, but not the files that the installer places on your ESP. Thus, you must uninstall those files manually, as just described. To complete the job, you'll also have to remove /boot/refind_linux.conf, and perhaps the /etc/refind.d directory.
+ + +Uninstalling rEFInd from OS X
+ + +The easiest way to restore the standard OS X boot loader on a Mac is not to uninstall rEFInd; it's to bypass it. This can be accomplished with the Startup Disk item in the System Preferences panel:
+ +
+ +
Select your startup disk (Macintosh HD OS X, 10.11.3 in this example) and then click Restart. The computer should reboot into OS X, bypassing rEFInd.
+ +I recommend stopping here, because the procedure for completely removing rEFInd from a Mac depends on your installation method and tends to be challenging for many Mac users, who are unfamiliar with the necessary command-line tools. Basically, you must reverse the steps described earlier, in Installing rEFInd Manually Using Mac OS X:
+ +-
+
+
Uninstalling rEFInd from Windows
+ + +From Windows, you must reverse the directions for installing in Windows—type mountvol S: /S to mount your ESP as S:, then navigate to the S:\EFI directory and delete the refind subdirectory.
+ + +Post-Uninstallation Activity (UEFI-Based PCs)
+ + +On a UEFI-based PC, when the computer boots and cannot find the rEFInd files, it should move on to the next boot loader in its list. In my experience, some EFI firmware implementations remove boot loaders they can't find from their NVRAM lists, so nothing else will be required, provided you have another working boot loader in your firmware's list. If your firmware doesn't automatically clean up its NVRAM entries, rEFInd's entry will do little harm; however, you can delete it with the efibootmgr utility in Linux:
+ ++# efibootmgr --verbose +Timeout: 10 seconds +BootOrder: 0000,0007 +Boot0000* rEFInd HD(2,1b8,64000,f1b7598e-baa8-16ea-4ef6-3ff3b606ac1e)File(\EFI\refind\refind_x64.efi) +Boot0007* CD/DVD Drive BIOS(3,0,00)PATA: HP DVD Writer 1040r . +# efibootmgr --delete-bootnum --bootnum 0000 +Timeout: 10 seconds +BootOrder: 0007 +Boot0007* CD/DVD Drive+ +
This example shows use of efibootmgr's --verbose (-v) option to display boot programs so as to identify which one is rEFInd, followed by --delete-bootnum (-B) to delete a boot program and --bootnum (-b) to identify which one to delete. Of course, in this example there's not much else left, so you'd presumably want to install another boot program at this point! If you already have another one installed, you may want to check the BootOrder line to determine which one will take precedence when you reboot. If you don't like what it shows, you can adjust it with the --bootorder (-o) option; consult efibootmgr's man page for details.
+ +If you're not using Linux, you may be able to find a utility that serves +a similar function. Under Windows, the bcdedit command, described +in the section on installing rEFInd under Windows, +may work, although I've not attempted this.
