This reminds me of the old quote DON'T PANIC, though I forget the
colouring that was part of the skit.

I have had the issue that UEFI looses all boot information for a disk
drive. Personally I hate complexity, and UEFI is just that, more
complexity than benefit (personal opinion only).

I would assume that you have already checked the below possible
solutions?  If not, let me know if this could work?



The BIOS Recovery tools are software designed to recover a corrupted


How Do I Initiate BIOS Recovery On A Dell Laptop?

Before you begin the BIOS Recovery, ensure that the laptop's battery
is charged up to at least 10%.


Verify that the laptop is powered OFF and disconnect the AC adapter.


Press and hold the CTRL key + ESC key on the keyboard.


Plug in the AC adapter to the laptop.


Release the CTRL key + ESC key on the keyboard once you see the BIOS
recovery screen.


On the BIOS Recovery screen, select Reset NVRAM(if available) and
press the Enter key. Select Disabled and press the Enter key if you
wish to save the current BIOS settings.


Select Recover BIOS and press the Enter key to start the recovery

Note: Your Dell PC may restart a few times during the process of BIOS

Note: This works slightly differently for Alienware Notebooks. Please
follow the steps below instead. 


Shut the PC down and remove the AC adapter cable


Press and hold the CTRL and ESC keys together while carrying out the
next steps


Connect the AC Adapter cable and press the PC's power button


Release the CTRL and ESC keys as soon as the power button LED is lit


Select option Recover BIOS and wait until it finishes

I have never heard of a Linux distro, let alone Ubuntu, wanting to
update the BIOS. Further, if this was thing, I would have expected
it to ask first, possibly more than once.

Something apparently went wrong during the BIOS flashing and now the
laptop is a brick.

I have looked around on the web, but I can't see any evidence that
Ubuntu would pre-emptively update the BIOS during an O/S upgrade.

Is this a thing, or has the laptop been infected with some sort of
