If you wish to go to replace it with a Windows 9x operating system, use a
Windows 9x boot disk, if you don't have one try
www.bootdisk.com, boot with
the disk, at the "a" prompt, type fdisk and press enter. Select delete the
non-DOS parition and delete it.
If it says there is not non-DOS partition, delete the primary DOS partition,
then create a new primary DOS partition, set it active, reboot with the boot
disk still in the drive, at the "a" prompt type "format /u" without the
quotes and press enter. If you are going to install Windows ME, don't type
the forward slash and the "u" it is not supported in ME. When formatting is
complete, change to the CD-ROM drive, place the Windows CD in the drive,
setup, press enter and follow the screens.
If you are not going to install Windows 9x ignore the above but in the
future try to be less cryptic in your questions so we can be of better help.
