My buddy is letting me look into his next book that will not boot. What it does is it shows nextbook logo after you press the power button, after that it flashes the windows 10 logo and then black screen. A cursor appears if you move the track pad but disappears soon after. It stays on the black screen indefinitely. I have tried to repair it, but no luck either, always fails. It cannot boot from usb either so I cannot reinstall windows that route either. Does anyone know if I can use a micro usb to female usb to boot windows to reinstall ? Or anyone else have any ideas ? Thank you.
