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.
