i want to reformat my hard drive, and i read some of teh answers that you gave and i think that they are half-assed answers. you say just to type reformat c: at a dos prompt then reinstall windows. Dont you have to copy your sys files to a floppy? what about all your drivers? and when you do install it, how does your computer know if you have a dvd-rom? last time i did it, computer didnt know i had cd-rom and couldn't run windows cd. i want to know everything there is to know.
