About a week ago I tried to install Cyberlink Power DVD 10. I kept getting error message 1625, this installation not allowed due to system policy. I've gotten conflicting solutions and still no luck. As of today I tried messing with the registry and local policies etc...long story short, I cannot get past my "Starting Windows" window. It powers down, then powers back up and gives me the options of 'start windows normally' or 'repairs'. It will not start normally nor can it repair the problem. Have I done something heinous and can it be reversed? Is there a way to get it into safe mode, back to my desktop so I can restore the backed up registry.
