Can't boot....weird situation [Solved]

[Huckleberry Finn]

... After setting up esp I was unable to boot into any of my live usbs or my system...

I would reset Cmos once more (after removing the battery press the power button to drain the remaining electricity (when it's unplugged)).

It must be a coincidence cause there's no relation with the existence of a partition and non booting usb sticks (Windows or Linux).


Edit: I saw the last part of your post just now :)

I believe I have solved what started all this mess...........

It appears the Mx21 ahs with kernel 5 is a signed kernel, which allowed me to boot and install mx21 even though secure boot was enabled. At some point after installation when I was setting up the machine to suit me I installed ahs kernel 6, which is not signed. That would explain why I was suddenly no longer able to boot into the mx21 on my system.

I think............LOL

As to why I ended up where nothing would boot and I could only get to the screen that said "secure boot system image did not authenticate" I haven't figured out.

Thought I would post this in case it helps someone else down the road.
