hi this is my first post and got a little problem thats bugging the tits off me!i recently added a second hard drive,and for some daft reason i put xp onto it,i soon realised this was a bit pointless so i formated the drive,however now when i boot up.a message always says there is part of windows missing,i hit return with this ,then get a message asking with windows xp i want to boot up,so basically it still thinks theres 2 os,help?
