Used KillDisk - Now Recovery Disk Wont Boot Up


I have a Sony Laptop that runs with Vista that I wanted to sell.  I used KillDisk to wipe the hard drive before selling.  However, when I try to load the recovery discs to bring it back to factory settings, it does not load up.  I am getting a "Missing Operating System" message.

The laptop has a partition that houses an on-board recovery tool.  When I try to load that and recover from there, it gives me a "Missing C Drive or C Drive is too small".

Please advise me on what I need to do to be able to load my Factory Settings back on my laptop.

I have an old copy of a Windows 2000 that I can use.  However, it does not even load when I put it in and turn on the computer.
that is caused by the fact that your lappie is trying to boot from disk
in the bios, change the boot priorito to CD drive first
