Installing the Boot management software rEFInd
- Download: http: //sourceforge.net/projects/refind/files/0.10.3/refind-bin-0.10.3.zip/download
- Extract the package;
- Refind-install run the installation script;
- After rebooting you should be able to see the start menu rEFInd
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.
