I have similar issues. Im nervous as i dont want to trash my xp system. Ive made the right partions with qparted but when it gets to the grub part of the knoppix installer ive stopped it says mbr or root partition now im not going to do mbr but if i do root partition will it mess things up as well? To be honest id rather just use smart boot manager and boot from dvd whenever i want to use linix.
So whats the next step thats not going to ruin my xp install?
