ok so i actually run windows xp on my computer and i wanted to get vista. so my girlfriend was trying to be sneaky and suprise me by installing vista on my computer. sweet huh. anyway she has a lap top that came with vista already installed so she thought that she could put in her application cd that came with her laptop and clean my computer for a fresh boot with her operations disk. well since she did this my computer will not get past the dell sign when i boot up after the dell sign it just shows a little blinking line in the top left corner. i have tried to use my xp disk to reboot but when i pick to run from cd it tells me to press f1 to retry boot or press f2 for system utilitys. i have no idea how to fix this i have even tried running boot disks and data recovery doctors and nothing happens. can some one get me going in the right direction. thanks
