Uninstall Windows2000

Hi Experts,

I installed Windows98 and Windows2000 in the same PC. Now, I want to uninstall Windows2000. Can you tell me now to do that? Step by step :)

Thank you in advance.

Basically, boot to 98 and make a boot floppy (or download one from www.bootdisk.com).  Boot to the floppy and run the following command at the A:\> prompt:

C:\WINDOWS\COMMAND\SYS C:

Then reboot.

Now delete the WINNT directory, c:\WINNT

Any reason you want to remove 2000... it's newer, better, still supported, based on NT technology which allows MUCH greater stability, better memory management, considerably more useful diagnostic info when an error occurs... I could go on...
