Hello. I have a dell dimension 9100. I have two drives on it, a ~160gb drive that came with it with xp, and a 500gb drive with win7. I put the win7 in myself and had been using that. Finally, I decided to erase the old drive with xp on to install linux on it. After erasing the old drive, my computer won't start up. It says it cant find sata 1 or 3. I've tried switching the cables hooking up to it but that doesn't help. If I push continue after it tells me how it can't find them, it says 'loading pbr for descriptor 2...done' and stays there. I did not erase windows 7, I checked. Whats wrong?
