Hi there, I have a quite simple question, whilst trying to run a repair I accidentally reinstalled XP again and now have it twice on the computer. When starting up I have to select the correct partition which is nothing short than annoiying!!! I would really like to remove the second installation as it now takes approx 4 mins for the system to boot up but am not sure how to and also how to locate it to remove it. Can anyone help? thanks a lot, Jez
