I downloaded Mountain Lion from the Mac App store (this morning), configured unibeast using a MacBook running 10.6.8 and the plugged it in. I select USB and hit enter. The Apple Logo is shown and then the screen goes black (and the monitor says 'No input detected.'

I've tried to unplug the GT 630 and use the onboard graphics (HD 2500) and it went past the Apple logo and through to the installation. I installed it but halfway through, I get the error 'OS X Install failed.' I then found out that the HD 2500 isn't compatible. I plugged the GT630 back in and have tried the flag -x which does not work. I then tried the flag PCIRootUID=0 as well as PCIRootUID=1, GraphicsEnabler=0 and GraphicsEnabler=1 which also did not work. Where do I go from here?

I am using the following components:
Intel i5 3470
MSI GT 630
Gigabyte H77-WIFI
8GB 1600MHz RAM
Samsung 830 120GB
Seagate 500GB
Corsair CX-430
Bitfenix Prodigy
 
Screen goes black after Apple logo [SOLVED]

I've solved this problem by buying a GT 640 instead.
