Hello, I am having a problem rebooting my Windows 10 device. I am getting a message Boot Device Not Found

Can you pass diagnostics?
Tap the ESC key after powering on

Tap it about once a second after you see the LEDs on the keyboard flash.

Press F2 to run diagnostics.
Do not allow any updates if disk or memory fail, especially a BIOS update.

if the disk is good and the memory tests passes then try a startup repair

To do a startup repair you need boot into windows recovery mode. First read this article about safe mode.
Skip down to 'Enter safe mode from outside windows'. If f11 does not get you into system recovery then try turning the power on and off three or more times in a row.
When you get to advanced options select 'Startup Repair'

If the startup repair fails then try the restore point.

This video describes how to use a restore point.  Ignore that it shows windows working.  Clicking on "System restore" will bring up the list of restore points similar to what is in the below video.

Let me know if you need more help or if startup repair fails.
