I wouldn't have liked to explain disks, file systems, partitions or any of what Winston had to deal with over the Internet, or even over the phone.
But here is my solution, for the future.
Boot off the Windows 2000 CD
Your C: will already contain Windows 98
You'll need to format and partition the drives (and reformat) anyway, so here's what I generally do (now that FDISK won't work for my NTFS drives).
Boot off the Windows 2000 CD, install a new Windows - it will tell you that another Windows is currently installed to C:
Before you do this however, you'll need to delete all of the partitions in the list of partitions (or partition table).
Once you've got RAW on every disk, you can create partitions (as many as you want).
Once this has been created, Windows setup will ask for the file system (FAT32, NTFS) and you'll be able to QuickFormat the drive, for clean installation of Windows 2000.
This isn't as complicated as the above step, and only takes a minute or so (pushing a few buttons, confirming the actions, etc).
Booting up using the Windows 2000 CD: half a minute
Deleting existing partitions: 10 seconds
Creating new partitions: half a minute
Formatting the partition: a minute
This can be done in 2-3 minutes tops.
But in the past, I would have used Winston's method if I had a FAT32 disk, and Windows 98 (installing Windows 98 again, or another 9x kernel).
