Hi ,

I've bought and downloaded Mountain lion.
I followed the steps on the site and installed it to a usb using unibeast.
However I cannot get to the installation screen or even a kernel panic.
Every time I boot it , I get to the boot loader and launch the usb.
I get the Apple Logo loading screen and after about 10 - 20 sec my screen loses its source and goes black.Than after awhile my pc restarts.

I have tried verbose mode but cannot read the last few lines before my screen goes blank.And I've tried some boot flags like graphics enabler , pcirootuid and -x .But still the same process occurs.

BTW I have installed lion before using unibeast and as far as I can remember it worked without any trouble.

My Specs

ASUS P5KPL AM/PS
Intel Core 2 Duo E7500
NVIDIA GTX 465

Does anyone have this problem or even better some sort a solution

Was having the same issue. Used PCIRootUID=0 when booting to the installer. Problem solved :)

try booting with GraphicsEnabler=Yes. It worked for me. Then install the latest CUDA drivers and you should be able to boot normally.

Hi Bjlive45,

you said you used PCIRootUID=0 when booting to the installer... what does that mean? what exactly do you do/type? Could you please post a step by step as I don't know how to do that but have the sam eproblem with the black screen?

thanks

At the boot screen where you select bot drive, press tab

then type PCIRootUID=0 hit enter

This method works for me.
