i know this is gonna be the dummest question you've ever had but i'm getting so frustrated i have no choice but to ask :} ok i got my computer with win98 installed and my roomate had winME so i reformatted and installed that but never got a copy of the disk and now i've been having massive problems with ME and i wanna go back to 98 till XP comes out but the problem i'm having is that i can't reformat cuz i can only use the dos promp that's in windows and when i reboot using my system disk it says "insuficient space" and then gives me a dos prompt but every command i give it besides C: is a "BAD COMMAND" and the win98 disk won't do anything cuz it's an older version. please help me...
