OSX installation fails (reboot before any screen comes up)
After starting upgrade from 10.6 to 10.8 the system don't started. I tried to reinstall 10.6 from DVD and USB stick, but before the initial setup screen come up the system restart. the same happens with 10.8.
There is also no possibility to use the recovery disk Assistant, the system restarts before I see any screen.
If I use a Windows7 DVD I can install it without any problem. Does anybody have a hint for me what I can try to get my OSX back?
Is this a good question?
