Apologies for the newbie-ish question, but I'm finding myself in a bit of a bind here. Basically I was attempting to dual boot Windows and Linux, and the typical partitining horror story kicked in and basically my mbr is completely messed up so I'm in the process of trying to get things back in order, if possible.

Anyway, I've been trying to figure out ways to format my hard drive since my Win98SE bootdisk didn't work(driver error), and the Windows Full Install CD is having problems detecting my hard drive, so what I decided to try and do is run Knoppix from a CD and use Fdisk to format my drive, but embarrassingly enough I'm completely new to Linux so I'm really not sure how to use Fdisk to format. Would anyone mind helping me out with this one? Any input is really appreciated, thanks.
