|What do you want to be able to do ?|
Do you have a problem you're trying to fix ?
If yes, what is it ?
There is a set of "Setup" floppies you can make from downloads that, if you have a floppy drive, you can use to load the same files that the Windows 2000 CD initially loads when your computer is able to boot from the CD drive - it's intended for computers that for one reason or another cannot boot the computer from the Windows 2000 CD. The downloads to make those are available either from the site jowah referred to or from the Microsoft web site.
All they do is get you to the point (the first screen where you can respond) where you can choose to Repair Windows (by pressing R and loading the Recovery Console) or continue on to run Setup from the 2000 CD. You MUST have a Windows 2000 CD in a drive to proceed from that point.
