I was chasing a Hijacker and got carried away.... Anyway, I can't get the DOS prompt, all I get is the 4 start-up options. Whenever I select one of those, it ends up in a gray screen and won't let me do anything. I tried holding down F8 and that doesn't work either. I copied a start disk for ME from the web, but I can't figure out how to boot from it. Help!
