I have a Compaq Presario 6000. A friend messed up my computer and then reinstalled windows xp. Now my computer will not detect the 2nd cd drive (cdr/rw) and my hard drive which was 40 GB now only shows 1.99 GB. Reinstallation is not an option because I don’t have and can’t get a copy of windows xp. Can some one help? ( please note: I am not interested in anyone’s pirate copies of windows, I just want to fix the problem.)
