If you really want to format your hard disk restart your pc, while it will boot press a key to show command list (different motherboards use different keys, for mine it's "f12"), the corresponding button you have to press is shown when you start your pc. Then type in "C:format" or "c: format c:" (considering C: is your hard drive) and it should be done. All you have to do is to follow the instructions.
Your hard drive will be clean after few minutes.
there is also the easier way if you have your booting diskette. Just insert it before your pc boots, it will show the command list and all you have to do is to type "C:format C:" and then when it asks are you sure just type "y"
