I tried updating my NUC 2820 to the latest v50 bios. It seemed successful, but I lost the ability to get into the Visual BIOS. F2 at boot does nothing. F7 does work, but attempting to downgrade the BIOS to v48 or, re-install v50 fails. The message is "Flash Update Failed (8000000000000007,0).
Anyone know what that means? I also am unable to get the "Power Button Menu". Holding the power button at startup does nothing. Requesting the Visual BIOS at the Visual Boot Manager also does nothing.
I should add that my Windows 7 OS comes up normally. Are there any Windows tools to access the BIOS settings?
