There are many ways to dual boot Windows and Mac OS X with different boot loaders on MBR but for UEFI, there’s only Clover boot loader is capable if you set it up correctly. In order to dual boot with Clover by default, you need to install Clover to EFI folder –> rename bootmgfw.efi to bootmgfw-orig.efi in the efi/Microsoft/boot/ folder. When we renamed this bootmgfw.efi, the bios will boot from clover BOOTX64.EFI in the efi/boot/ folder and the Clover boot GUI will come up with all the Windows and Mac OS X partition for us to select and boot correctly.
