If you have problems, feel free to drop me a line. Note: I consider rEFInd to be beta-quality software! That said, rEFInd is a usable program in its current form on many systems. If you're unsure which boot method your computer uses, check the first of the subsections, What's Your Boot Mode. My page on the CSM describes how it works and why it can create problems in more detail. Thus, you may be using BIOS-style booting on an EFI-based computer. Even so, many modern PCs support both EFI-style booting and BIOS-style booting, the latter via a BIOS compatibility mode that's known as the Compatibility Support Module (CSM). Prior to mid-2011, few computers outside of Intel-based Macs used EFI but starting in 2011, computer manufacturers began adopting UEFI in droves, so most computers bought since then use EFI. You will not find rEFInd useful on older BIOS-based computers or on systems with other types of firmware, such as older PowerPC-based Macs. (I use "EFI" to refer to either version unless the distinction is important.) You're likely to benefit from rEFInd on computers that boot multiple OSes, such as two or more of Linux, macOS, and Windows. Thus, the rEFIt family of boot managers has become fairly populous.Īs already noted, rEFInd is a boot manager for EFI and UEFI computers. In 2020, RefindPlus emerged as a fork of rEFInd with features intended to support older Macs with third-party video cards, which can be difficult to get working.

The Clover boot manager is a different fork of rEFIt that's used mainly as a Hackintosh (macOS on stock PC hardware) boot utility. Since rEFInd's release, Chrisoph Pfisterer, rEFIt's author, has begun pointing to rEFInd as its successor project. REFInd is a fork of the earlier rEFIt boot manager, which has not seen any development since 2010. 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. I've heard of others that are just as bad. The worst I've personally encountered is on Gigabyte's Hybrid EFI, which provides you with no boot options whatsoever, beyond choosing the boot device (hard disk vs. Unfortunately, in practice these boot managers are often so poor as to be useless. In theory, EFI implementations should provide boot managers. See my Web page on this topic for more information. In fact, since version 3.3.0, the Linux kernel can function as an EFI boot loader for itself, which gives rEFInd characteristics similar to a boot loader for Linux. If you're using Linux, you should be aware that several EFI boot loaders are available, so choosing between them can be a challenge. All EFI-capable OSes include boot loaders, so this limitation isn't a problem. Many popular boot managers, such as the Grand Unified Bootloader (GRUB), are also boot loaders, which can blur the distinction in many users' minds. rEFInd is not a boot loader, which is a program that loads an OS kernel and hands off control to it. Like rEFIt, rEFInd is a boot manager, meaning that it presents a menu of options to the user when the computer first starts up, as shown below. This page describes rEFInd, my fork of the rEFIt boot manager for computers based on the Extensible Firmware Interface (EFI) and Unified EFI (UEFI). If all else fails, the new (rEFInd 0.13.0) feature to boot via an EFI firmware boot option may help see the description of this feature here. Using rEFInd 0.13.0 and booting via the Preboot loader option should work around these problems. Second, a bug in rEFInd 0.12.0's memory management could cause it to hang on some EFIs, including some that Apple rolled out as part of the macOS 11 upgrade. With recent versions of macOS, rEFInd normally presents both options, but users might reasonably hide the poorly-named Preboot option, which is the only one that works. First, and confusingly, macOS 11 requires booting via the boot loader Preboot partition, not the main macOS installation partition. Note: I've seen reports that rEFInd is failing to boot macOS 11 ("Big Sur"). If you find this Web page useful, please consider making a small donation to help keep this site up and running.
