I have successfully created a bootable Knoppix DVD which I did to try and sort out my PC HD which is in a partition mess.

I have unsuccessfully tried to install Linux over a newly installed Windows XP system - trying to dual boot. The Linux install failed and will not boot; neither will the XP system.

I have also failed to repair the system ( it is SUSE) because of issues with GRUB.

I came across Knoppix as a Linux system which can be run from a DVD stand alone.

I want to just start from scratch with the hard drive and initially just create a DOS partition so that I can re-install Windows and then attempt to put a Linux (Dual booted).

When I tried to fdisk sda from Knoppix it didn't do anything failing to find sda1 etc - can anyone point me in the right direction as to how to partition the system
