Wiping the hard drive...saving the OS
I'm helping a friend this weekend. Her mother died and she wants to sell her mother's computer after it is cleaned up. I was planning to use something like DBAN to wipe the drive first, but those programs typically wipe out the OS, too. She wants the computer to have the OS on it when she goes to sell it. I have not been able to find any disks with the OS. Is there some way I can securely wipe the hard drive and end up with the currently-installed OS (Win XP Home Edition) back on it if I don't have the installation disks.
