Could somebody explain me why my system is only working with "Clover Legacy"? I have a H77 Pro 4/mvp ASROCK and an I7 3770. ATI Card included. When I use Clover UEFI my system won't boot and it wants a bootable device when rebooting. Why? I have an UEFI system. I installed it via Unibeast in UEFI mode. Why do I have to chose legacy Clover then? hat does not make any sense. Seems like it doesn't know how to start from EFI. Help would be appreciated.
