OdysseyX86J4105 no longer boots to Windows

It used to boot to windows, now boots to EFI shell. Tried resetting BIOS to default - no help. Tried Windows Recover - nothing happens.


You can upgrade your BIOS again by referring to this document (Firmware Upgrade | Seeed Studio Wiki)

I tried this and ended up at the same place - in the EFI shell.

Other suggestions?
