Ok, old thread I know. My brother is having the same/similar problem right now. His Windows XP install just reboots and safe mode doesn't work.

He's tried booting from the CD and selecting repair - but he says that just ends up dropping him into a command prompt and doesn't actually do anything. To be specific, after selecting the repair option it asks for his admin password - he doesn't remember setting one so he pressed enter which drops him to the prompt. If he types some random incorrect password it says it's wrong.

Any advice?
