I installed mandrake 9.1 a little while ago and I'm not too impressed. I actually prefer to run knoppix from cd over the mandrake install. I would like to try the hd install of knoppix, but don't know how to get rid of the mandrake install.

Any simple advice for a windows user/linux newbie-like the linux equivilent of format c: ?

Also-do I need to remove the boot loader too before installing knoppix to the hd?

thx
