Guys! I need help please!


Specs:


Motherboard Model: MSI P55-GD55 (MS-7589)
Intel core i5 2.6ghz
Graphics : Msi geforce 9500gt 512mb
12gb ddr3


Im trying to run Mountain Lion. I was able to get ML installed on my external drive (usb) using my Mac Book Pro, ran multi beast everything went smoothly. It boots perfectly on my MAC book, but when i take it my hacintosh build (specs above) I get the black screen when I boot the Mountain Lion drive. I've had Snow Leopard running on the Hackintosh build for a few years with no problem.
I've tried all the options and searched for days for a fix. None of these worked (GraphicsEnabler=No, PCIRootUID=0, PCIRootUID=1, ) please help.

FIXED!!!

for those who it might help...

i had to disconnect my other HD's from the PC. So only the drive i wanted to install ML on and the USB with the Mountain Lion Install were connected. At the boot screen before i selected ML typed : PCIRootUID=0 GraphicsEnabler=Yes

Thank You Baby Jesus..... Amen
