Don't forget to disable UEFI Capsule Updates in setup for BIOS 1.1.26 ASAP so Windows Update doesn't reinstall 1.1.27. At this point, the easiest thing would be to re-image the SSD. CAVEAT: Any personal files created and stored on the NVME SSD after you made that  image will be lost. That could include recent emails etc. etc. So you have to make that decision. Depending on how old the image is, you may have a bunch of Windows and other updates to install. The thing you need to know is if BIOS was set to RAID or AHCI when you made the image, and make sure it's set the same way before re-imaging the drive. But, if it's not set correctly the first time you try, you could just change the setting to the other option and re-image the SSD again. If do you decide to make a clean OS install, with the caveats about personal files and updates mentioned above, as long as BIOS is set to AHCI before you launch the Windows Installer, it will configure the OS for AHCI and install the right drivers automatically. What a mess they made of this... 
Hi Gurus, My Dell XPS 8930 Desktop does not boot after BIOS ( Ver 1.1.27 dated Dec 12, 2022) update attempt yesterday. BIOS update was triggered by Dell Technical notification email for my computer. I did not get any error message during the update but computer never rebooted. When I turn on the computer it gets stuck at the Dell Logo screen, power button LED also sometimes blinks 5 times. I tested the cmos battery with multimeter it is showing 3V, so that’s not the issue. I also shortened the CMOS jumpers, just in case but no luck. I also tried the Control & Esc procedure, still no luck. When I press Cntrl/Esc during boot, I see the blue progress bar at bottom of screen and also “F2/F12” options but If I press F2 or F12  during boot, it does not take me to Bios screen. Any chance of revival at this stage? Otherwise, my options now, as I see them, are either to buy a new computer, or replace the motherboard. I would prefer to reuse the Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz, M.2Nvme 500GB storage, 16 GB of memory, etc in new motherboard. I am debating should I get exactly same motherboard (Dell price quote $230) or get something different, not sure which motherboards will fit in the case and utilize the components also.  Any suggestions / guidance will be highly appreciated. Different mother board will get rid of Maxx Audio Pro, a plus point. Thanks for your time and Happy Holidays.
XPS 8930, BIOS 1.1.27, no boot
