Help with formatting my hard drive So I want to format my hard drive because my computer has become overloaded with useless junk, but the problem is I can't figure out how to do it. With my laptop I just go into the setup menu before the computer boots up and there is an option there to do it. I went to the setup screen on my desktop but can't find any option similar to that. Also once the computer is booted up I go into my computer, right click on the C drive and click on format but that doesn't work either. I have a dell computer with a p4 processor and I'm using Windows XP. Thanks for the help.
