rEFInd is a tool designed for auto-detecting all your installed EFI boot loaders.

rEFInd can auto-detect your installed EFI boot loaders, and it presents a pretty GUI menu of boot options. rEFInd is capable of handling systems with many boot loaders, it also gives better control over the boot loader search process, and provides the ability for users to define their boot loader entries.
