i've recently decided to reinstall windows and from there set up a dual boot system, i'm running a 2.8ghz/512ddr/80gb fedora core 3 box. A dos bootable disk won't recognise any commands, probably because none of the drives i specify are linux drives and dos doesn't know what a linux partition looks like. my windows cd doesn't want to boot up at start up, probably because of the same problems that the dos bootable disk had. i made a fc3 rescue cd, but i'm afraid i don't quite understand it well enough to make it do what i want. my command prompt does not respond to fdisk, cfdisk, or mkfs. simply put, i want to clean whipe my hard drive so windows can get a foothold. any suggestions?
