I have no idea why this happened. I certainly never touch the BIOS
except when I buy a new computer, just to check that secure boot is off.
Otherwise I keep well away.
Still, all is well, so I am happy,
I'd imagine it was probably fwupd pulling a new firmware upgrade for
your laptop - which usually resets certain values to defaults. In your
case it turns out that (as predicted) your diagnosis was wrong and your
system _does_ boot in ye olde BIOS mode, not EFI. So when it reset and
turned off Legacy Mode the UEFI firmware couldn't "see" the bootable
components on disk and threw the dreaded "no bootable operating system
found".
That being said I think you use MX Linux... which doesn't look like it
includes fwupd at all, let alone ships and enables it by default.
Sometimes system firmware does just reset itself, simple as that.
We are definitely at the point - and have been for some time now - that
clinging to the old MSDOS disk layout + BIOS to initialise your computer
in 2020 unless you have very specific technical reasons is not a good
choice. GPT disks + UEFI were invented for a reason, and any system
built in the last 10 years or so defaults to it for a reason as well.
