My friend came to me with a problem about his computer. He unknowingly had a pirated copy of XP pro 2000, and tried to update. Well needless to say, he cannot log on to windows now. He doesnt have anything on the computer worth keeping, so I am just going to give him another OS. Question is: How do I erase Windows and install, say, Freebsd(or any other OS) using DOS? Ive been working on this for a while now and would be grateful for any help!
