Windows 10: Computer freezes and cannot find Boot Device for restart

My computer freezes on occasion, gathers information and tries to reboot but No Boot device found. The computer makes several attempts but fails. Need to manually shut down computer and reboot. If it can reboot after a manual shutdown, why can it not reboot when it tries after the freeze? And how do I fix this? Running Windows 10 on a 64 bit laptop. Have pulled hard drive and reseated and assured that the hard drive is first on the reboot list.
