In that case I have 2 options-
1- Clean install windows 7 ultimate, then install SP1 before any other updates or
2- Clean install windows 7 Ultimate including SP1.
Am I right in thinking these are my only options? Or is there a way to sort this without losing all my data? (Even though I've backed it up.)
If so, where can I find a download of option 2 and will my Key still work?
P.s., thanks for the replies.
