Cause

BCD (Boot Configuration Data) entry is incorrect after the recovery on uEFI system. Then the parameter "device" in Windows Boot Manager is deleted after the recovery.

Solution


WORKAROUND:
Perform the below step on the restored OS.

1. Open Command Prompt.
2. Run "bcdedit".
3. Run "bcdboot c:\windows".
4. Reboot the system.

Or boot from "Windows Boot Manager" after temporarily booting from Disk 0 since "Windows Boot Manager" is updated once the booting is successful.
