Today I tried to upgrade Snow Leopard to Mountain Lion but I have some troubles with it:
I have 3 partitions: Windows 7, Snow Leopard and MyHack OS X Install Disk (Can't find any USB stick with a storage of 8Gb).

If I boot up my pc and choose my install partition for Mountain Lion, first the Apple logo shows up (if I use the flag -v it stuck at "pci configuration begin") and after a while my screen tells me "No input".

PC specs:
4GB Ram
NVIDIA GeForce GT 230
Intel® Core™ Duo CPU E7400 @ 2.80GHz

Do I something wrong or did I forget something?

Kind Regards,
WhizZz

Remove SleepEnabler.kext or boot with the appropriate PMVersion= flag.
Use the search to find more information, I don't remember how it works, I've never used SleepEnabler.
