Sounds like a big headache lol. I might try it out and like what you did, I can always delete the partition if its no good. Cheers for the info!

Certainly don't waste any money on another key for Windows 7 before you've tried it properly. When you install Windows and it asks for a key don't put anything in, leave it blank. You have 30 days to try it before you have to activate Windows with a valid key.
