Dual Boot Yosemite and Windows 8.1

We have already discuss about Hackintosh Boot Loader but still this time we are providing Detail guide Dual Boot Yosemite and Windows 8.1 with GUID Partition Table using Clover Boot Loader,Clover is an open-source EFI-based boot loader which has a totally different approach from Chameleon and Chimera, in fact it can emulate the EFI portion present on real macs and boot the OS from there instead of using the regular legacy BIOS approach used by Chameleon and Chimera. This highly recommended for UEFI motherboard.
