MokManager Error - this is a *serious* issue! *Please help!*

Edit:

I had a look around here. Oh, forget it. No one helps anyone else here, unlike in the Mac community 😄 !

I get the error message below when I try to boot from any OS other than the restored Windows 11 Pro. This is serious because I need to use Debian Linux on this excellent laptop. How to I clear the UEFI EEPROM? Is it at all possible?

Here is the error message, typed verbatim from a photo I took.

Failed to open \EFI\mmx64.efi - Not Found
Failed to load image : Not Found
Failed to start MokManager: Not Found
Something has gone seriously wrong: import_mok_state() failed: Not Found

Please have mercy on this poor soul and help me solve this horrible dilemma! I have been tearing my hair out over this for several days. If you help me fix this you are HERO forever!

Many thanks in advance!

Apart from a few Workstations, HP provides no support for Linux.

I mention this because with Windows, we can provide links to videos and HP Documents. We can provide links to HP diagnostic apps you can download and run on your PC. We can provide links to HP drivers and to HP BIOS updates, which you can also download and run on your PC. And, nearly everything useful can be done using an application or utility that HP will provide you for free.

For the general population of HP customers trying to use or install Linux, we have NONE of that. No diagnostics. No videos. No downloadable utilities or tools. And, once you get into Linux, you discover that you have to become VERY familiar with the command line to do anything complicated. We have no command line scripts or examples to provide you.

So when I recommend going to the support forum for your Linux distro, it is because THERE is where you will get the amount and kind of support you need.
