Hadn't used the tablet in over a month. Charged it up. When booted I get the April Setup Utility screen with the messages:
ROM Image Update Denied
EFI_NOT_FOUND ROM Image is not loaded
Flash Update Parameters
IIRC I had this issue a while back, but telling it to load defaults would allow it to boot into Win10. Not this time.
What can I try to recover this tablet?
Thanks for posting.
You will have to perform a recovery back to factory specs, then reinstall the Windows 10.
