hey guys i have an acer extensa 5630 and basically all i want to do is whipe it clean and start fresh ( i dont care about my documents etc) BUT i have kinda half installed a windows 7 upgrade kit on it, so ive tried pressing alt f10 and startup and nothing happens... then i have to choose weather i want to start it with vista or windows 7 ( i choose vista as i havent paid for windows 7 so its not a full copy ... hard to explain) any ideas how i can do this
