hello I already have macOS sierra installed on one of my hard drives. since I have more room I was wondering could I just add windows to the hard drive as well. iv read up a little but mostly people who have dual boot set it up in the beginning and I all ready have my mackintosh up and running :/ . I understand that installing windows erases the efi for macOS so if I just copy that folder and back up the clover stuff then install windows then boot back into Mac with a usb drive then replace the clover files it will be dual boot then and work properly. does anyone know if that theory works? I just don't want to mess up. thanks
