A:Answer go to your search window and type in "create a recovery drive"
you'll need at least a 16GB usb flash drive that will be completely erased, so make sure it is new or reformat to new state...once you have that usb stick, put it in a usb drive and click that "create a recovery drive"...it walks you through your steps and takes about an hour. Then if you need to reinstall, just put in the recovery drive in usb slot and follow directions
