Do you WANT to reinstall Win98?
If not, then simply boot from the Win2K CD-ROM and follow the instructions.
One of the first questions asks if you want to repartition and/or reformat.
Say Yes. Unless you plan to install Win9x/ME on this computer, choose to
format NTFS all the way. NTFS is much more secure than FAT, both in the
sense of security from unauthorized access and in the sense of security from
hard disk glitches.
Unless you plan to reinstall Win98 (or to format a larger-than-32GB
partition as FAT32), there is no reason to keep the old DOS/Win98 boot disk.
Throw it away (or at least hide it so that you won't be tempted to use it
again). Use the Win2K CD-ROM to do the initial partitioning and formatting.
After you get Win2K up and running, use Disk Management (type diskmgmt.msc
at the Run prompt) to do any additional partitioning, formatting, drive
letter assignment, etc.
