but the computer doesn't boot from CD

I'd fix that first since the 6 floppy boot is usually too hard for many to get working. DVDRW drives are not that expensive today compared to just a few years ago and I would expect a Windows 2000 owner to be able to do the minor work to get the new drive installed.

Too bad the formatting of the post was off. Maybe the make, model and details are there but I missed them.
