When installed the system to make a mistake

There is a XP computer, let me say that to help re-look, I take my DELL plate to give him the equipment, the results of the first half of the equipment to a power failure, and then the caller then installed, although the driver has no end but the My DELL drivers do not give him security.Now seemingly become a dual system, how to remove the newly installed, the new clothes are loaded into the disk D, C in the original disk does not move

choice is either you take your disk systems of the newly installed system where the disc to disc format, or the safe mode, remove the disc D under WINDOWS But if not clean cut will be a problem, use the hard disk D useful things to copy it down, the format
