Sorry if this is a dumb ? but I cant figure out how to boot my cpu into dos from the usb stick. Ive been trying all day to flash my xbox drive with no success. Ive read countless guides and seen the video tut 25 times. When I got into dos earlier, my screens were different than the one on the video and I couldnt get anything to work. I know im missing somthing simple, but im just not understanding everything. HELP! Thank You!
