I am not sure if you can do this in 2000 but you can in XP. Put in a floppy, Go to my computer>>right click the a:>>format>>
See if there is an option to create a boot disk. If there is, do it then boot to DOS. In dos then you can type format c:\
If you are planning on installing another operating system, you can just boot off of the CD and during the install process it will kill the partition and format.
