OK, I just did this. It worked.
I have two Katanas (B13VGK) - a 15" and a 17". I have twin Samsung 990 Pros in each and needed to update the firmware on them. They were 3-4 revisions behind because I had to work up the nerve to do this, lol
1. Boot into Safe mode:
Open an elevated command prompt and run:
bcdedit /set {current} safeboot minimal
2. Enter the following command to boot into the BIOS screen. It will save you from having to peck at the DEL key.
shutdown /r /fw /t 0
3. Enter Advanced Mode:
In the BIOS "Advanced" screen, use
Right-Shift + CoPilot + Left-Alt + F2 to reveal the hidden menu.
4. Disable VMD:
Choose "System Agent(SA) Configuration";
Choose "VMD setup menu";
Change "Enable VMD controller" to "
Disabled".
Save Changes and reboot. You'll be in Safe mode.
6. Reboot into normal mode:
After Windows boots into Safe Mode, open an elevated command prompt and run:
bcdedit /deletevalue {current} safeboot
then reboot one more time.
7. If you open the Device Manager, there should now be a "Standard NVM Express Controller" device under Storage Controllers. I'm not certain whether it's necessary to go back and re-enable the VMD. I'll see what happens.
