#1 Get rid of the upgrade disk, and get a full version of Win2K Pro or winXP. The Upgrade disk isn't going to help you becuase yo have to upgrade from an OS you can't do a fresh install. Also throw out your Windows 95/98 Cd's or use them as costers because that is about hom much they are worth.
Most Win2K cd's are bootable so all you will have to do is throw the CD in the drive and boot of the CD, much easier. If you need a copy of the CD let me know I'm sure I could throw an image of the Cd up on an FTP site somewhere.
