Ok, which option in that link would I have to use? From reading it I would assume I should try to do option 1 first, then if that doesn't work, I should use the workaround. Will I need my windows xp key to do this installation?
As for moving the hard drive, no, i have not built the new computer yet
but once it happens I would think I can just do the re-installations again. Just to clarify, I am using student edition upgrades of Win7, both the pro and home editions, would microsoft let me do the whole home/pro switchover once i get the other computer set up?
