Unable to boot up Linux Mint 22

[Leonard_Klamann]

Hey folks,

I am trying to get into Linux, using my FW13 (12th Gen Intel i5 CPU) and Linux mint (Mint 22 - cinnamon), upon etching the iso onto a thumb drive I tried booting from said drive with success. However I was unable to start the installation procedure at that point and when retrying it a couple days later the only response I got was the following.

as a complete noob I have no clue what to do with this, I tried redownloading the .iso and toyed around with the boot manager (diabled secure boot and the like) but all to no avail, Linux mint would start up without the above message.

I hope I gave you all nessecary info to help me on that, again I am new to all that so apologies if I forgot something.

Try resetting your BIOS to default settings then disable secure boot again. The mok issue should likely be due to an issue with secure boot and the iso.

Here’s some more information about import_mok_state(): https://www.reddit.com/r/pop_os/comments/16tf1vl/something_has_gone_seriously_wrong_import_mok

If you are unable to solve your issue, try checking online for solutions.

Hey Elliot, thank you for your reply.

I have not found a way to “reset the BIOS” in the BIOS Guide. I tried it by removing the RTC battery for a couple of seconds but if it had the desired effects the results were not different.

I am going to take a look at the reddit post you shared and see if I can find a solution through it.

Hey Leonard!

I think I had the same problem, but with FW13 Ryzen 7040. I was getting the exact same response. I found the following forum:
https://forums.linuxmint.com/viewtopic.php?t=412942
And the response from the original poster on Feb 2 gave me most of the answer I needed:
“For those having the same problem I manage to overcome it by doing this:
I putted the Linux Live USB on my other computer, went to the ¨\EFI\BOOT\¨ folder inside the flash drive and copied the ¨grubx64.efi¨ file…”

It seems “bootx64.efi” is not for us to boot with, and you need to guide BIOS to grubx64.efi instead of letting it choose automatically.

I re-etched my thumb drive (just in case), powered up without the thumb drive and spammed F2 to get the BIOS settings. I turned off the secure boot, which prompted another restart, and restarted without the thumb drive again spamming F2. When the BIOS menu started, I plugged in the thumb drive, entered “boot from file,” and booted from \EFI\BOOT\grubx64.efi. I don’t think you have to do all the stuff in that forum of messing with the linux image. This worked for me and I was able to open the live session of Mint Cinnamon and then install it.

You’ve probably handled this by now, but I hope this at least helps people in the future!

Best,
Owen
