I have a Dell Dimension 2100 that is currently running Windows ME. I want to format the HD and install Windows xp Black edition. But I can't access the Bios settings. I read the help file and it says to press Ctrl until the main screen comes up. Also says you can try F8. I did it 50 million times. Nothing happens. I tried all the F keys. Still nothing. The cd itself is an iso [boot disc] and it works fine (I upgraded the computer I'm using right now) Please help. Thanks in advance.
