+<h2>Installing rEFInd Using an RPM or Debian Package File</h2>
+</a>
+
+<p>Beginning with version 0.6.2, I've included an RPM package file for rEFInd, and I quickly updated this (in 0.6.2-2) to be more sophisticated and to include a Debian package file, as well. 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:</p>
+
+<pre class="listing"># <tt class="userinput">rpm -Uvh refind-0.6.2-2.x86_64.rpm</tt></pre>
+
+<p>On a Debian-based system, the equivalent command is:</p>
+
+<pre class="listing"># <tt class="userinput">dpkg -i refind_0.6.2-2_amd64.deb</tt></pre>
+
+<p>Either command produces output similar to that described for <a href="#installsh">using the <tt>install.sh</tt> script,</a> 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.</p>
+
+<p>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 <tt>install.sh</tt> uses might not last for long. You might therefore want to use <tt><a href="#mvrefind">mvrefind.sh</a></tt> to move your rEFInd installation to another name after you boot Linux for the first time from rEFInd.</p>
+
+<p>Since version 0.6.2-2, my package files have installed the rEFInd binaries to <tt>/usr/share/refind-<tt class="variable">version</tt></tt>, the documentation to <tt>/usr/share/doc/refind-<tt class="variable">version</tt></tt>, and a few miscellaneous files elsewhere. Upon installation, the package runs the <tt>install.sh</tt> script to copy the files to the ESP. This enables you to re-install rEFInd after the fact by running <tt>install.sh</tt>, should some other tool or OS wipe the ESP or should the installation go awry. In such cases you can <a href="#installsh">use <tt>install.sh</tt></a> or <a href="#manual">install manually.</a></p>

<h2>Installing rEFInd Using <tt>install.sh</tt> under Linux or Mac OS X</h2>
<p class="sidebar"><b>Warning:</b> If you're using a Macintosh, you should run <tt>install.sh</tt> from Mac OS X rather than from Linux. If run from Linux, rEFInd is unlikely to be fully installed. Worse, it's conceivable that running <tt>install.sh</tt> from Linux will damage your firmware, requiring that it be re-flashed. The reason is that Apple uses non-standard methods to enable a boot loader, and the Linux functions in <tt>install.sh</tt> assume standard EFI installation methods.</p>
-<p>If you're using Linux or Mac OS X, the easiest way to install rEFInd is to use the <tt>install.sh</tt> script. Under Linux, this script installs rEFInd to your disk's ESP. Under Mac OS X, the script installs rEFInd to your current OS X boot partition by default; but you can install to your ESP instead by passing the script the <tt>esp</tt> option.</p>
+<p>If you're using Linux or Mac OS X, the easiest way to install rEFInd is to use the <tt>install.sh</tt> 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, <tt>install.sh</tt> 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 <a href="#extra_installsh">extra instructions</a> for this utility.</p>
-<p>Before running this script under Linux, you should ensure that your ESP is mounted at <tt>/boot</tt> or <tt>/boot/efi</tt>, as described in more detail in the <a href="#linux">Installing rEFInd Manually Using Linux</a> section. (If you installed Linux in EFI mode, chances are your ESP is properly mounted.) This precaution isn't necessary under OS X.</p>

+
+<p>Under Linux, the <tt>install.sh</tt> script installs rEFInd to your disk's ESP. Under Mac OS X, the script installs rEFInd to your current OS X boot partition by default; but you can install to your ESP instead by passing the script the <tt>--esp</tt> option. Under either OS, you can install to something other than the currently-running OS by using the <tt>--root <tt class="variable">/mountpoint</tt></tt> option. (See <a href="#table1">Table 1</a> for details.)</p>

+<p>Before running this script under Linux, you should ensure that your ESP is mounted at <tt>/boot</tt> or <tt>/boot/efi</tt>, as described in more detail in the <a href="#linux">Installing rEFInd Manually Using Linux</a> section. (If you installed Linux in EFI mode, chances are your ESP is properly mounted.) This precaution isn't necessary under OS X. If you run <tt>install.sh</tt> 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 <a href="#mvrefind"><tt>mvrefind.sh</tt> script.</a></p>

-<li>If you intend to boot BIOS-based OSes, such as most Windows
- installations and some Linux installations, you <i>must</i> edit the
- <tt>refind.conf</tt> file, as noted near the end of the installation
- script's output. (Note that rEFInd can only boot such OSes on Macs at
- the moment.)</li>

+ though; because of the popularity of dual boots with Windows on Macs,
+ the BIOS/legacy scans are enabled by default on Macs.</li>
+
+<li>On Linux, <tt>install.sh</tt> checks the filesystem type of the
+ <tt>/boot</tt> directory and, if a matching filesystem driver is
+ available, installs it. Note that the "<tt>/boot</tt> directory" may be
+ on a separate partition or it may be part of your root (<tt>/</tt>)
+ filesystem, in which case the driver for your root filesystem is
+ installed. If <tt>install.sh</tt> detects that the filesystem in

+ partition and you install an appropriate driver, the

+ correctly. Some systems will require manual tweaking to
+ <tt>refind_linux.conf</tt>, though—for instance, to add
+ <tt>dolvm</tt> to the boot options on Gentoo systems that use LVM.</li>
</ul>
+<p>In addition to these quirks, you should be aware of some options that <tt>install.sh</tt> supports to enable you to customize your installation in various ways. The syntax for <tt>install.sh</tt> is as follows:</p>
+
+<pre class="listing">
+install.sh [--esp | --usedefault <tt class="variable">device-file</tt> | --root <tt class="variable">mount-point</tt> ] \
+ [--nodrivers | --alldrivers] [--shim <tt class="variable">shim-filename</tt>] [--localkeys] [--yes]
+</pre>
+
+<p>The details of the options are summarized in <a href="#table1">Table 1.</a> Broadly speaking, they come in four classes: installation location options (<tt>--esp</tt>, <tt>--usedefault</tt>, and <tt>--root</tt>), driver options (<tt>--nodrivers</tt> and <tt>--alldrivers</tt>), Secure Boot options (<tt>--shim</tt> and <tt>--localkeys</tt>), and a user input option (<tt>--yes</tt>). Using some of these options in unusual conditions can generate warnings and prompts to confirm your actions. In particular, using <tt>--shim</tt> or <tt>--localkeys</tt> when you're <i>not</i> booted in Secure Boot mode, or failing to use <tt>--shim</tt> when you <i>are</i> booted in Secure Boot mode, will generate a query and a request to confirm your installation. Consult the <a href="secureboot.html">Managing Secure Boot</a> page for more on this topic.</p>

This option is only useful on OS X; on Linux, installing to the ESP is a practical necessity, so <tt>--esp</tt> is implicit on Linux. Be aware that some users have reported sluggish boots when installing rEFInd to the ESP on Macs.

The <tt class="variable">device-file</tt> should be an <i>unmounted</i> ESP, or at least a FAT partition, as in <tt>--usedefault /dev/sdc1</tt>. Your computer's NVRAM entries will <i>not</i> be modified when installing in this way. The intent is that you can create a bootable USB flash drive or install rEFInd on a computer that tends to "forget" its NVRAM settings with this option.

To use it, you should mount your regular installation at <tt class="variable">/mount-point</tt>, including your <tt>/boot</tt> directory (if it's separate) at <tt class="variable">/mount-point</tt><tt>/boot</tt> and (on Linux) your ESP at that location or at <tt class="variable">/mount-point</tt><tt>/boot/efi</tt>.

The script also adds an entry to your NVRAM for rEFInd at this location. You cannot use this option with either <tt>--esp</tt> or <tt>--usedefault</tt>, except for implicit use of <tt>--esp</tt> on Linux. Note that this option is <i>not</i> needed when doing a dual-boot Linux/OS X installation; just install normally in OS X.</td>

+ <td>Ordinarily <tt>install.sh</tt> attempts to install the driver required to read <tt>/boot</tt> on Linux. This attempt works only if you're using ext2fs, ext3fs, ext4fs, or ReiserFS on the relevant partition. If you want to forego this driver installation, pass the <tt>--nodrivers</tt> option.

+</tr>
+<tr>
+ <td><tt>--shim <tt class="variable">shim-filename</tt></tt></td>
+ <td>If you pass this option to <tt>install.sh</tt>, the script will copy the specified shim program file to the target directory, copy the <tt>MokManager.efi</tt> file from the shim program file's directory to the target directory, copy the 64-bit version of rEFInd as <tt>grubx64.efi</tt>, and register shim with the firmware. (If you also specify <tt>--usedefault</tt>, the NVRAM registration is skipped.) The intent is to simplify rEFInd installation on a computer that uses Secure Boot; when so set up, rEFInd will boot in Secure Boot mode, with one caveat: The first time you boot, MokManager will launch, and you must use it to locate and install a public key. This key file will be located in the rEFInd directory's <tt>keys</tt> subdirectory under the name <tt>refind.cer</tt>. Note that I'm not providing a shim binary myself, but you can download one from <a href="http://www.codon.org.uk/~mjg59/shim-signed/">here.</a> In the not-too-distant future, most distributions will provide their own shim programs, so you'll be able to point to them—for instance, in <tt>/boot/efi/EFI/fedora/shim.efi</tt>.</td>
+</tr>
+<tr>
+ <td><tt>--localkeys</tt></td>
+ <td>This option tells <tt>install.sh</tt> to generate a new Machine Owner Key (MOK), store it in <tt>/etc/refind.d/keys</tt> as <tt>refind_local.*</tt>, and re-sign all the 64-bit rEFInd binaries with this key before installing them. This is the preferable way to install rEFInd in Secure Boot mode, since it means your binaries will be signed locally rather than with my own key, which is used to sign many other users' binaries; however, this method requires that both the <tt>openssl</tt> and <tt>sbsign</tt> binaries be installed. The former is readily available in most distributions' repositories, but the latter is not, so this option is not the default.</td>
+</tr>
+<tr>
+ <td><tt>--yes</tt></td>
+ <td>This option causes the script to assume a <tt>Y</tt> input to every yes/no prompt that can be generated under certain conditions, such as if you specify <tt>--shim</tt> but <tt>install.sh</tt> detects no evidence of a Secure Boot installation. This option is intended mainly for use by scripts such as those that might be used as part of an installation via an RPM or Debian package. <b>Note:</b> I introduced this option with the 0.6.2-2 incremental release, which was primarily an update of the 0.6.2 RPM package; it's not yet available in the mainline 0.6.2 version.</td>

<p>In any event, you should peruse the script's output to ensure that everything looks OK. <tt>install.sh</tt> displays error messages when it encounters errors, such as if the ESP is mounted read-only or if you run out of disk space. You may need to correct such problems manually and re-run the script. In some cases you may need to fall back on manual installation, which gives you better control over details such as which partition to use for installation.</p>

+<h3>Installing rEFInd Manually Using Mac OS X</h3>
</a>
<p>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 <tt>refind_x64.efi</tt> file with them; but very early Intel-based Macs have 32-bit EFIs (and sometimes 32-bit CPUs), which require the <tt>refind_ia32.efi</tt> file. You can determine whether your Mac needs the <i>x</i>86-64 or IA32 build by typing the following command in a Mac Terminal window:</p>
unless you're certain you do <i>not</i> have an Advanced Format hard
disk.</li>
+<li>If you don't want to reboot immediately after installing rEFInd, you
+ may optionally unmount the ESP by typing <tt class="userinput">sudo
+ umount /dev/disk0s1</tt> or <tt class="userinput">sudo umount
+ /Volumes/esp</tt>. This step isn't strictly required, but if you want
+ to keep the ESP out of your directory tree, it can be useful.</li>
+
</ol>
<p>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 <tt>bless</tt> 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.</p>
<p>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 <tt>bless</tt> 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.</p>

+<h3>Installing rEFInd Manually Using Windows</h3>
</a>
+<p class="sidebar"><b>Warning:</b> Windows 8 implements a fast shutdown feature that helps speed up shutdown and startup operations on a single-boot computer. Unfortunately, this feature can cause filesystem corruption if it's used on a multi-boot computer. You can disable the feature by launching an Administrator Command Prompt window and typing <tt class="userinput">powercfg /h off</tt> in it.</p>

<p>To install rEFInd under Windows, you must first find a way to access the ESP, which Windows normally hides from view. One way to accomplish this goal, and to proceed forward once the ESP is accessible, is as follows:</p>
<ol>
</ul>

+<h3>Installing rEFInd Manually Using an EFI Shell</h3>
+</a>
+
+<p>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 <tt>bcfg</tt> 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.</p>
+
+<p>In addition to emergency situations, using <tt>bcfg</tt> can be desirable if <tt>efibootmgr</tt> 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 <a href="#naming">alternative names for rEFInd.</a></p>
+
+<p>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 <tt>shellx64.efi</tt> (for <i>x</i>86-64) or <tt>shellia32.efi</tt> (for <i>x</i>86) in the root directory of the ESP. Thus, you can try copying your shell file there. You can obtain EFI 2 shells here:</p>
+
+<ul>
+
+<li><a href="https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2/ShellBinPkg/UefiShell/X64/Shell.efi"><i>x</i>86-64 (64-bit) shell 2</a></li>

+
+</ul>
+
+<p>Note that the 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. Once you've booted the shell, you can proceed as follows:</p>
+
+<ol>
+
+<li>If you haven't installed rEFInd previously, unpack its zip file to a
+ FAT partition. This can be the ESP itself or another partition, such as
+ a USB flash drive. If you're simply repairing a lost NVRAM entry, you
+ needn't move your existing rEFInd files.</li>
+
+<li>Identify your filesystems, which are labelled with the form <tt>fs<tt
+ style="variable">n</tt>:</tt>, as in <tt>fs0:</tt> for the first
+ filesystem, <tt>fs1:</tt> for the second, and so on. Type the
+ filesystem number followed by the Enter key to begin using it. You can
+ then type <tt class="userinput">ls</tt> or <tt
+ class="userinput">dir</tt> to see the contents of the filesystem.
+ Chances are your ESP will be <tt>fs0:</tt>, but it could be something
+ else. (The following steps assume your ESP is <tt>fs0:</tt>; you'll
+ need to adjust them if it's not.) If rEFInd's source files are on
+ another device, you must identify it, too.</li>
+
+<p class="sidebar"><b>Note:</b> Skip ahead to step #9 if you're merely re-activating an already-installed rEFInd binary. If an entry exists but it's no longer the primary one, you can skip ahead to step #14.</p>
+
+<li>If necessary, create a directory for rEFInd by typing <tt
+ class="userinput">mkdir fs0:\EFI\refind</tt>. (If the <tt>fs0:\EFI</tt>
+ directory doesn't already exist, you must create it first,
+ though.)</li>
+
+<li>Change to the directory in which rEFInd's files exist.</li>
+
+<li>Type <tt class="userinput">cp refind_x64.efi fs0:\EFI\refind</tt> to
+ copy the rEFInd binary file. (Adjust the name if you're using a 32-bit
+ computer.)</li>
+
+<li>Type <tt class="userinput">cp refind.conf-sample
+ fs0:\EFI\refind\refind.conf</tt> to copy and rename the sample rEFInd
+ configuration file.</li>
+
+<li>Type <tt class="userinput">cp -r icons fs0:\EFI\refind\</tt> to copy

+
+<li>Optionally, type <tt class="userinput">cp -r drivers_x64
+ fs0:\EFI\refind\</tt> to copy rEFInd's 64-bit drivers. (You could
+ instead copy the 32-bit drivers or limit yourself to just the drivers
+ you need, of course.)</li>
+
+<li>Type <tt class="userinput">fs0:</tt>, if necessary, to change to the
+ ESP.</li>
+
+<li>Type <tt class="userinput">cd \EFI\refind</tt> to change to rEFInd's
+ installation directory.</li>
+
+<li>If you want to edit rEFInd's options, type <tt class="userinput">edit
+ refind.conf</tt> and use the shell's built-in text editor to do so.
+ Press F2 followed by the Enter key to save your changes and F3 to
+ exit.</li>
+
+<li>Type <tt class="userinput">bcfg boot dump -b</tt> to see a list of
+ existing NVRAM entries. Pay attention to their numbers (labelled
+ <tt>Option:</tt> and <tt>Variable:</tt>, with the latter number
+ preceded by the string <tt>Boot</tt>, as in <tt>Boot0007</tt>). You'll
+ want to create a boot entry for rEFInd using a number that's not in
+ use.</li>
+
+<li>Type <tt class="userinput">bcfg boot add 3
+ fs0:\EFI\refind\refind_x64.efi "rEFInd"</tt>, adjusting the number
+ (<tt>3</tt> in this example), filesystem (<tt>fs0:</tt>), and filename
+ (<tt>\EFI\refind\refind_x64.efi</tt>) as necessary for your system. If
+ you're used to Linux, be sure to use backslashes (<tt>\</tt>), not
+ Linux-style forward slashes (<tt>/</tt>) as directory separators. Note
+ that some shells may ignore the number you entered and use another one,
+ so watch for this possibility.</li>
+
+<li>Type <tt class="userinput">bcfg boot mv <i>3</i> 0</tt>, substituting
+ the option number for the entry you created for <tt
+ class="variable">3</tt>. This moves rEFInd to the top of the boot
+ order.</li>
+
+<li>Type <tt class="userinput">reset</tt> to reboot the computer.</li>
+
+</ol>
+
+<p>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 <tt class="userinput">bcfg boot dump -b</tt> 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 <a href="#naming">fallback filename</a> that your firmware will recognize.</p>
+
<a name="naming">
<h2>Alternative Naming Options</h2>
</a>
+<p>Some EFI implementations do a poor job of honoring the boot options set via Linux's <tt>efibootmgr</tt> 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. Broadly speaking, there are two alternative names that are most useful:</p>
+
+<ul>
+
+<li><tt class="userinput">EFI/BOOT/boot<i>arch</i>.efi</tt>—This name
+ is the official EFI fallback filename. It's most commonly used on
+ bootable removable disks, but it can be used on hard disks. It's
+ typically used only if no NVRAM entry points to a valid boot
+ loader.</li>
+
+<li><tt class="userinput">EFI/Microsoft/Boot/bootmgfw.efi</tt>—This
+ filename has no official special standing in the EFI specification, but
+ as a practical matter, many EFI implementations use it as a fallback
+ boot loader in addition to or instead of
+ <tt>EFI/BOOT/boot<i>arch</i>.efi</tt>. In fact, some give it such a
+ high precedence that you can't boot anything that's not given this
+ name!
+
+</ul>
+
+<p>If you need to use one of these names, or something more exotic, you can do so in either of two ways: You can <a href="#mvrefind">use the <tt>mvrefind.sh</tt> script</a> to move your installation in one step, or you can <a href="#manual_renaming">move and rename your files manually.</a></p>
+
+<a name="mvrefind">
+<h3>Using <tt>mvrefind.sh</tt></h3>
+</a>
+
+<p>The easiest way to move a rEFInd installation, at least in Linux, is to use the <tt>mvrefind.sh</tt> script. If you installed from one of my RPM or Debian packages, this script should be installed in <tt>/usr/sbin</tt>, 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 <tt>mv</tt> command, but you pass it the directory in which a rEFInd installation appears and a target location:</p>
+
+<pre class="listing">
+# <tt class="userinput">mvrefind.sh /boot/efi/EFI/BOOT /boot/efi/EFI/refind</tt>
+</pre>
+
+<p>This example moves rEFInd from <tt>/boot/efi/EFI/BOOT</tt> to <tt>/boot/efi/EFI/refind</tt>. It differs from <tt>mv</tt> in several ways:
+
+<ul>
+
+<li>The script renames rEFInd in a way that's sensitive to its source and
+ destination directories—for instance, <tt>mvrefind.sh</tt> knows
+ that rEFInd (or shim, for Secure Boot installations) must be called
+ <tt>bootx64.efi</tt> on a 64-bit installation in
+ <tt>/boot/efi/EFI/BOOT</tt>, so it looks for rEFInd under that name
+ when copying from this directory, or it renames rEFInd to that name
+ when copying to it.</li>
+
+<li>The script creates a new NVRAM entry for rEFInd when it copies to any
+ location but <tt>EFI/BOOT</tt> or <tt>EFI/Microsoft/Boot</tt>. It
+ refuses to copy to such locations if it's not run from an EFI-mode
+ boot.</li>
+
+<li>The script knows enough to back up existing boot loaders stored in
+ <tt>EFI/BOOT</tt> or <tt>EFI/Microsoft/Boot</tt> when copying to these
+ locations. For the former location, the script backs up
+ <tt>EFI/BOOT</tt> as <tt>EFI/BOOT-rEFIndBackup</tt>; for the latter, it
+ moves <tt>EFI/Microsoft/Boot/bootmgfw.efi</tt> to
+ <tt>EFI/Microsoft/bootmgfw.efi</tt>.</li>
+
+</ul>
+
+<p>The <tt>mvrefind.sh</tt> script is likely to be useful in resolving boot problems—if your system won't boot, you can try copying the installation to <tt>/boot/efi/EFI/BOOT</tt>, <tt>/boot/efi/EFI/Microsoft/Boot</tt>, and <tt>/boot/efi/EFI/refind</tt> in turn, testing the boot process after each attempt. (These filenames all assume your ESP is mounted at <tt>/boot/efi</tt>.) You could also copy a BIOS-mode install from <tt>/boot/efi/EFI/BOOT</tt> or <tt>/boot/efi/EFI/Microsoft/Boot</tt> to <tt>/boot/efi/EFI/refind</tt> to make it more robust against Windows repairs (assuming your firmware isn't broken).</p>

+<h2>Fixing a Sluggish Macintosh Boot</h2>
+</a>
+
+<p>I've received a few reports of a sluggish boot process (a delay of about 30 seconds before starting rEFInd) on some Macs after installing rEFInd. I've been unable to replicate this problem myself, and its true cause remains mysterious to me. I have found <a href="http://ubuntuforums.org/showpost.php?p=12256273&postcount=200">a Web forum post</a> describing a possible fix. Be aware, though, that this procedure involves using the <tt>efibootmgr</tt> 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:</p>
+
+<ol>
+
+<li>Boot into Linux.</li>
+
+<li>Type <tt class="userinput">efibootmgr</tt> as <tt>root</tt> to obtain a list of your boot loader entries. Each entry includes a boot number, as in <tt>Boot0003</tt> or <tt>Boot0027</tt>.</li>
+
+<li>Remove all of the boot loader entries <i>except</i> rEFInd's by using <tt>efibootmgr</tt>'s <tt>-b <tt class="variable">bootnum</tt></tt> option to specify the boot entry and <tt>-B</tt> to delete it. For instance, typing <tt class="userinput">efibootmgr -b 0027 -B</tt> as <tt>root</tt> deletes boot entry <tt>Boot0027</tt>. Issue a separate <tt>efibootmgr</tt> command for each boot entry.</li>

+<p>Some sources suggest that delayed launches of rEFInd on Macs are more common when installing rEFInd to the ESP, so if you've done this, you could try re-installing it to your OS X boot partition.</p>

+<h2>Uninstalling rEFInd</h2>
+</a>
+
+<p>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). In Linux, a command like the following, typed as <tt>root</tt>, should do the trick:</p>
+
+<pre class="listing">
+# <tt class="userinput">rm -r /boot/efi/EFI/refind</tt>
+</pre>
+
+<p>This example assumes that your ESP is mounted at <tt>/boot/efi</tt> and that rEFInd is installed in <tt>EFI/refind</tt> on that partition. If you've mounted your ESP elsewhere, or installed rEFInd elsewhere, you should adjust the command appropriately.</p>
+
+<p>The same procedure works in OS X, with the caveat that the ESP isn't normally mounted in OS X and rEFInd is installed to the OS X boot partition by default. You'll also need to use <tt>sudo</tt> to acquire <tt>root</tt> privileges. Thus, you'd probably use a command like the following in OS X:</p>
+
+<pre class="listing">
+$ <tt class="userinput">sudo rm -r /EFI/refind</tt>
+</pre>
+
+<p>Many variants of both of these commands are possible on both OS X and Linux. For instance, you'd probably use <tt>sudo</tt> on Ubuntu; and if you installed rEFInd to your ESP on a Mac, you'd need to first mount the ESP and include its path in the <tt>rm</tt> command.</p>
+
+<p>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 <tt>/boot/refind_linux.conf</tt>, and perhaps the <tt>/etc/refind.d</tt> directory.</p>
+
+<p>From Windows, you must reverse the directions for <a href="#windows">installing in Windows</a>—type <tt class="userinput">mountvol S: /S</tt> to mount your ESP as <tt>S:</tt>, then navigate to the <tt>S:\EFI</tt> directory and delete the <tt>refind</tt> subdirectory.</p>
+
+<p>In any of these cases, 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 <tt>efibootmgr</tt> utility in Linux:</p>
+
+<pre class="listing">
+# <tt class="userinput">efibootmgr --verbose</tt>
+Timeout: 10 seconds
+BootOrder: 0000,0007
+Boot0000* rEFInd HD(2,1b8,64000,f1b7598e-baa8-16ea-4ef6-3ff3b606ac1e)File(\EFI\refind\refind.efi)
+Boot0007* CD/DVD Drive BIOS(3,0,00)PATA: HP DVD Writer 1040r .
+# <tt class="userinput">efibootmgr --delete-bootnum --bootnum 0000</tt>
+Timeout: 10 seconds
+BootOrder: 0007
+Boot0007* CD/DVD Drive</pre>
+
+<p class="sidebar"><b>Warning:</b> As noted earlier, <tt>efibootmgr</tt> has been linked to firmware corruption on some Macs, at least with pre-3.0 Linux kernels. Therefore, I don't recommend using <tt>efibootmgr</tt> on Macs.</p>
+
+<p>This example shows use of <tt>efibootmgr</tt>'s <tt>--verbose</tt> (<tt>-v</tt>) option to display boot loaders so as to identify which one is rEFInd, followed by <tt>--delete-bootnum</tt> (<tt>-B</tt>) to delete a boot program and <tt>--bootnum</tt> (<tt>-b</tt>) 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 loader at this point! If you already have another one installed, you may want to check the <tt>BootOrder</tt> 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 <tt>--bootorder</tt> (<tt>-o</tt>) option; consult <tt>efibootmgr</tt>'s <tt>man</tt> page for details.</p>
+
+<p>If you're not using Linux, you may be able to find a utility that serves a similar function. The OS X <tt>bless</tt> utility (or its GUI equivalent, the Startup Disk item in System Preferences) should do the trick; but Macs pick up standard OS X boot loaders when they boot and find that a configured non-standard boot loader is missing, so this shouldn't be necessary on Macs. Under Windows, the <tt>bcdedit</tt> command, described in the <a href="#windows">section on installing rEFInd under Windows,</a> may work, although I've not attempted this.</p>
