So following on from my last post I'v now tried again, this time using Rufus to make my boot USB rather than balena etcher which despite being reccomended is apparently problematic. I also downloaded and verified a fresh install of the cinnamon ISO.
Result is uh....
Failed to open \EFI\BOOT\mmx64.efi - Not Found
Failed to load image (windows symbol): Not Found
Failed to start MokManager: Not Found
Something has gone seriously wrong: import_mok_state() failed: Not Found
This happens when trying to boot from the USB so its actually worse than last time where the demo environment worked but it kept crashing on attempting a proper setup.
PC in question is a small notebook with no discreet GPU to speak of (Intel integrated graphics) that I've been hoping to use as a testbed before comiting to Linux on my main PC.___
I’m no expert, but that sounds like a UEFI/BIOS issue. Is your BIOS updated to the latest version? Could also be a secure boot issue. Maybe try turning secure boot off in the BIOS and see if it makes a difference.
No luck with secure boot, gonna see if I can find a bios update for this thing.
Edit: Aaaand Asus no longer offers bios updates for this model.
Aww bummer. Sorry I don’t have any better advice :/
