Just installed, now I can't boot. It comes to the boot loader, and as soon as I select OSX 10.9.3, it boots back to the BIOS screen. I installed from the new Multibeast 6.3. I tried using -x -v -f flags, commenting out GraphicsEnabler, nothing seems to work.
I have a GA-Z68XP-UD3 Motherboard, UEFI BIOS
Nvidia GTX-570 graphics
