Hi i'm new here was hoping I could get some help. I want to format my laptop. I don't have much space left on my hardrive and alot of files I don't use. There also seems to be alot of files taking up space that I can't find. My laptop came with windows vista already installed so it seems I can't format it. I have right clicked on my hard disk in my computer and clicked on format and it says " You cannot format this volume It contains the version of windows that you are using formatting this volume could cause your computer to stop working" Last time I did it on my old computer it was easy enough but now i'm stuck and can't recall what I did last time. Is there anyway I can format my computer without a vista disk myself?
