Computer reformatting/boothing help Hello. Ive been trying to reformat my computer for the last couple days now, and have had nothing but trouble. I have my BIOS set so that the primary boot drive is CD Rom (I have a Windows XP install disk). But whenever I restart my pc with the disk in and all, it goes to a dos prompt. I have no clue what to do here. Never is there something saying 'hit x key to boot from disk' or something similar. Any help would be great, thanks.
