I tried to install windows xp, and it was installing then my computer shut off. Now when I turn it ok it goes to a black screen with a little "_" blinking. I can't do anything. I can boot from the cd, so what do I do? I don't care if I loose files. I have most of them backed up. What do I do? I have an external hard drive if I need to use that. Edit: FIXED, thanks to finnschi.
