My notebook system runs Windows 2000 Professional and Windows 98 Second Edition (Win98SE). Several programs on the machine don't run well in Win2K Pro but run fine in Win98SE. How can I delete Win2K Pro from my machine?
The process is simple. Insert a blank 3.5" disk in the system and boot to Win98SE. At the command prompt, type
sys a:
This command automatically copies the necessary files to the 3.5" disk so that you can use it to boot to a Win98SE command prompt. Manually copy sys.com, fdisk.exe, and format.com to the 3.5" disk.
Boot to the 3.5" disk. At the command prompt, type
sys c:
This command removes Windows NT Loader (NTLDR) as a boot-sector controller. Reboot to Win98SE (you'll have no other boot options). You can now remove any files that relate to Win2K Pro. I assume that Win2K Pro is on a separate logical disk, which you can remove. (The Microsoft article "How to Manually Remove Windows NT or Windows 2000" at http://support.microsoft.com/support/kb/articles/q103/0/49.asp discusses the details of file and partition removal.) You can use PowerQuest's PartitionMagic, which costs about $60, to expand the C partition.
