He said "windows 2000 pro and then redhat 8"
Anyway, if you want to do it manually boot from Win9x bootdisk, type: fdisk /mbr (wipes out your mbr) than type: format x (substitute x for your drive letter). Windows 2000 will format the drive but it will do it in quick mode. So choose the mode that best floats your boat
EDIT: if you don't happen to have a Win9x bootdisk, go to http://www.bootdisk.com/original.htm
and get one
Also I would get new fdisk (Updated fdisk for Windows 98 bootdisks and/or systems for hard drives over 64 gig) http://www.bootdisk.com/dosfiles/fdisk.zip
