I'm having the exact same issue right now and it's killing me. In the case of my computer I don't have an extra HDD to use. All 8 of them are in use and cannot be consolidated. So...what do I do in this case?

Hi, not sure it it helps but I used the following flag on my X79-UD5

PCIRootUID=0

I also used it with npci=0x2000

I typed both of those in with out any other flags. If i used -v or -x it would not load.

Try do on the boot screen -x -v and PCIRootUID=0. It helped in my case.

you saved my life. thanks.for anyone who can't figure where to type this command. when unibeast screen apears where you choose USB just type this commands in one line separated by space
