What is an easy way to clear out a computer and OS when it has Win XP on it. For some reason when I was loading Win WP it got messed up and now I have to OS on it. And I tried to do a complete re-load and a fix on them both but it wont delete 1 so I still always have 2. And there is a bunch of crap on there that just needs to be deleted. I know you can do F-disk on older OS's but I am pretty sure it wont work. So what should I do. Also I have some disks made that are bootable like I was starting w/ nothing.
