Help, I installed 7 Ultimate upgrade on my laptop and must have fudged something so 7 installed on my backup D: drive partition and has left Vista Premium on the C:drive giving me an even slower dual OS option. I have looked at everything on both side an do not see a way to un-install 7 so I can go back and just upgrade on the C: drive and do away with Vista. Any bright ideas for a not so bright install?
