rEFInd is a fork of the rEFIt boot manager. Like rEFIt, rEFInd can auto-detect your installed EFI boot loaders and it presents a pretty GUI menu of boot options. rEFInd goes beyond rEFIt in that rEFInd better handles systems with many boot loaders, gives better control over the boot loader search process, and provides the ability for users to define their own boot loader entries.
