A graphical {,U}EFI boot manager.
rEFInd is a graphical boot manager for EFI- and UEFI-based computers, such as all Intel-based Macs and recent (most 2011 and later) PCs. rEFInd presents a boot menu showing all the EFI boot loaders on the EFI-accessible partitions, and optionally BIOS-bootable partitions on Macs. EFI-compatbile OSes, including Linux, provide boot loaders that rEFInd can detect and launch. rEFInd can launch Linux EFI boot loaders such as ELILO, GRUB Legacy, GRUB 2, and 3.3.0 and later kernels with EFI stub support. EFI filesystem drivers for ext2/3/4fs, ReiserFS, HFS+, and ISO-9660 enable rEFInd to read boot loaders from these filesystems, too. rEFInd's ability to detect boot loaders at runtime makes it very easy to use, particularly when paired with Linux kernels that provide EFI stub support.
