Assuming you are Currently Dual Booting ? Simply Delete the Windows 2000 Program Files Dir and the WIndows Directory. then edit boot.ini and remove the windows 2000 Entrys then set the defualt to the windows 98 Entry and set the timeout to 0 the system wil lboot 98 normally and windows 2000 is now uninstalled. You will still have 2000 boot files but it makes no Difference, that part you cant uninstall without reinstalling / Formatting the Partition ( you can but its abit Complicated ) Just want to Format and go back to 98 You Cant Format Coz the Drive is now NTFS, Dos format wont do it. Ok Follow These Instructions Carefully, Print them if u need to. Boot from the windows 2000 CD and follow thru normally and when you reach the Partitions Part, Delete the Partition. Now create another one. Go to the next part and choose FAT32 and let it finish When you get to the part its Copying Files Reset your COmputer and boot from your Dos Boot Floppy Disk. You can Now FOrmat and INstall WIndows 98
