So 'Eastfeild' asked how to kill his current OS's.
You guys debate his choice?
Why?
Eastfeild, if you would like a 'killer' 'OS killer'.
Try this:
delpart
'delpart' was a utility that came with NT3.5.
Still the best known HD cleaner.
It will get rid of anything. NTFS, Linux, whatever...
D/L it from the site, put it on a floppy.
Boot to a prompt in dos [use a 98 boot disk]
Run it, follow the bouncing ball, step back, and watch the destruction!
Then run fdisk etc, from your 98 floppy.
Install what you want bloke.
It's your box and your time.
Have Fun
