<h2>Introduction</h2>
-<p>This page describes rEFInd, my fork of the <a href="http://refit.sourceforge.net">rEFIt</a> boot manager for computers based on the <a href="http://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface">Extensible Firmware Interface (EFI) and Unified EFI (UEFI).</a> Like rEFIt, rEFInd is a <i>boot manager,</i> meaning that it presents a menu of options to the user when the computer first starts up, as shown below. rEFInd is not a <i>boot loader,</i> which is a program that loads an OS kernel and hands off control to it.
Many popular boot managers, such as <a href="http://www.gnu.org/software/grub/">the Grand Unified Bootloader (GRUB),</a> are also boot loaders, which can blur the distinction in many users' minds. rEFInd, though, relies on a separate boot loader to finish the handoff to an OS; it just presents a pretty menu and gives you options for how to proceed prior to booting an OS. All EFI-capable OSes include boot loaders, so this limitation isn't a problem. If you're using Linux, you should be aware that several EFI boot loaders are available, so choosing between them can be a challenge. In fact, the Linux kernel can function as an EFI boot loader for itself, which gives rEFInd characteristics similar to a boot loader for Linux. See <a href="http://www.rodsbooks.com/efi-bootloaders/index.html">my Web page on this topic</a> for more information.</p>

(Since version 3.3.0, the Linux kernel has included a built-in boot loader, though, so this distinction is rather artificial these days, at least for Linux.) Many popular boot managers, such as <a href="http://www.gnu.org/software/grub/">the Grand Unified Bootloader (GRUB),</a> are also boot loaders, which can blur the distinction in many users' minds.

-<p>In theory, EFI implementations should provide boot managers. Unfortunately, in practice these boot managers are often so poor as to be useless. The worst I've personally encountered is on <a href="http://www.rodsbooks.com/gb-hybrid-efi/">Gigabyte's Hybrid EFI,</a> which provides you with no boot options whatsoever, beyond choosing the boot device (hard disk vs. optical disc, for instance). I've heard of others that are just as bad. For this reason, a good EFI boot manager—either standalone or as part of a boot loader—is a practical necessity for multi-booting on an EFI computer. That's where rEFIt and rEFInd come into play.</p>

<p>I decided to fork the earlier rEFIt project because, although rEFIt is a useful program, it's got several important limitations, such as poor control over the boot loader detection process and an ability to display at most a handful of boot loader entries on its main screen. Christoph Pfisterer, rEFIt's author, stopped updating rEFIt with version 0.14, which was released in March of 2010. Since I forked rEFIt to rEFInd, Christoph has begun pointing rEFIt users to rEFInd as a successor project.</p>

<li>James Jesudason has a tutorial on installing Ubuntu 13.04 beta on a Macbook Retina Pro on <a href="http://randomtutor.blogspot.com/2013_02_01_archive.html">this blog page.</a> I'd recommend using a Linux filesystem driver to read the kernel directly from a Linux filesystem rather than copy the kernel to the OS X partition as in the tutorial, but either method will work.</li>
<li>The <a href="http://sourceforge.net/projects/cloverefiboot/">Clover</a> boot loader is a Hackintosh boot loader that incorporates, among other things, its own unique forks of rEFIt and of DUET (a <a href="http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=Welcome">TianoCore</a> tool to boot UEFI on BIOS-based computers).</li>
+<li>Pete Batard's <a href="https://github.com/pbatard/efifs">efifs</a> project aims to port GRUB's filesystem drivers to function as standalone EFI filesystem drivers. It's currently a work in progress but shows great promise, and several drivers are usable for limited purposes today.</li>
