hi all this might sound like a bit of a funny question but here goes. over the years i have had quite a few installs of windows, but a couple of months ago i decided to buy 2 500 gig hds and raid them and dual boot xp/vista, anyway had loads of problems so i decided to install xp on the raid array instead, but still had an old xp install on the old 200 gig hd, was ok for a while but started to give me problems again, now ive tried to reinstall a few times without the old hd in just the raid array and the system wont boot at all without the old hd connected, i dont want format the old drive cos it has important stuff i need i was simply going to reconnect it later and drag what i need over, but all the old install are still present when booting as i have a choice of 3 installs, only 1 of which works, so all i want is to start over make the system forget there was ever any install put on 1 raid array with no other hds in there and not to have to choose which install to boot up, any help would be appreciated.
