I was messing with my computer a few years back and i encountered . Not knowing what i was doing i ed my hard drive without owning a windows disk. After my it asked me to insert a windows software disk (I still dont have one or intend to buy one). I closed boot camp and never looked back. Now i need the space on my hard drive but its being wasted by this . Ive tried reopening and tried finding a way out but it continues to say i must finnish my original session. What should i do!!
