I installed (using upgrade option) Windows 2000 on a Dell Dimension 4100 that had ME previously. The upgrade itself wasn't smooth, I had to uninstall a bunch of apps before it would go, and perhaps I didn't uninstall everything I should have, because now the pc is really messed up.
The Windows login screen comes up, I log in using Administrator and the password, then a display dialog comes up saying "Loading your personal settings", and immediately after that another one saying "Saving your personal settins" and I'm back at the login window again.
I've tried safe boot, safe boot with networking, safe boot with command prompt, booting up the last known good configuration (must have been before windows was ever installed, I think) and none of them have any different effect.
Is there some other magic key combination that prevents windows from loading utilities, anti-virus software, whatever other trash is in the registry so that I can get a start prompt?
How do I fix this now?
