Not a real hardware program if Win 2000 was running successfully. What you need is FDISK on a floppy because it does not run dependably from CD on systems with NTFS disks. If 2000 is still running, insert the Win98 CD and make FDISK from the menu there. I believe it's in Add/Remove Programs, or maybe Add/Remove Windows Components, and it's called something like make a rescue disk or boot disk, but it has been a long time since I installed 98.
If 2000 is not still running, the easiest option is to find another computer running 98, 95, or possibly Millennium, but I'm not sure what support for FDISK is in Millennium. I do know that NT never had the tool to make FDISK floppies.
