How to fix "ERROR: Unable to find a bootable option. Press any key to shut down."?

This is what happened after I tried to restore using WDRT:



Operation ended with failure.
The software is not correctly signed or not signed for this device?

How to fix it?

This has been reported in the past in these forums. The only known solution is to have a service center diagnose and repair the device.
