I am trying to erase my hard drive and start over. I have done nothing but transfer one hard drive's info to the next for the last 8 years and now have an opportunity to wipe it clean and start all over. I have backed up the files that I needed to. My problem is that I have Windows XP and cannot get to a DOS prompt. Plus I cannot change my BIOS settings for some reason to boot from disk. If anyone can help me I would be most appreciative.
