How do I do it?
I tried to do it through the command prompt, didn't work, somebody told me I can't do it through the command prompt because XP is already running. Am I supposed to give it the command before XP starts? If so how do I do it?
Is there maby a website someone could send me too?

Thanks

Boor from the Windows XP install CD and hit R to go to the recovery console. Then format it from the command prompt as you normally would.

Or simply boot from the XP CD, commence a new install as normal, and when you get to the bit asking what partition to install on stop, delete the existing system partition and create a new one in its place. Install to that and it'll be freshly formatted for you as part of the install :)
