I've got a pretty big issue. Windows won't start on my desktop. It gets to the Windows loading screen, it will go up 2 or 3 bars then crash. Then it will take me to the error screen where it lets me start windows normally, from last working configuration, in safe mode etc,. No matter which one I click, it always crashes. This is not a problem on just one computer, its an issue on all of my desktops. Please help!
If (God forbid) you don't have your data backed up, you could try the Recovery Console first. Boot from your Windows XP CD and let it 'repair an existing installation.' This sometimes works, the big plus side being that it leaves your data intact.
Chances are that it's something with the Registry since this just happened to me a while ago. What you can do is create a registry in the Recovery Console with only the needed keys and boot XP from there and continue with a System Restore.
