I never even used the one I installed into a 2nd partition. Would the best thing to be to just remove it and then upgrade from Vista? Or should I leave it there and upgrade Vista to W7 and just keep the other instance of W7 where it is in the other partition?
I would format the W7 partition & use it for storage, backup my Vista files there, then format the Vista partition & do a "clean" Windows 7 install there. The little guy, I'd dump that too & add the space to the storage partition before my backup.
