Ok so i just made a windows xp startup disk. I am going to use this to format my hdd, because when building this computer, an extra partition was made on accident and now the computer thinks the 5gb partition is my main hdd, so it copys all the files onto that, so i need to format my hdd. The question i want to know, is after i restart my computer with the start up disk in. What do i do from there to format the hdd?
