Now I guess I've always been old school, with the discs and all but how do you install windows 7 and 8 on a external cd/dvd player or usb? Is it a problem not having cd/dvd drives? More or less I guess what I am asking is can you install fresh systems from external cd/dvd player and/or usb? Even if its a fresh clean build?
