Cannot enter BIOS setup in Compaq Presario 6000 desktop?!?

Question

I am currently trying to reformat my computer. The instruction manual says to press the F1 key when I see a black screen with the Compaq logo on it during startup, and this will take me to the BIOS setup screen. However, at startup, I don't see the Compaq screen at all, just the windows XP loading screen. I tried pressing F1 but nothing happens. Please someone help!!!

Answer 1

Press the F1 key as computer boots

Also try these keys

F2  DEL and F8 and CTRL+ESC

I have compaq c700 and these are some of the keys I can press

Also if you are trying to reinstall windows just reboot from CD and you should be OK
