I have created an USB key with Mint, but when I boot from it I get a few lines of errors
- Failed to open \EFI\BOOT\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
I have tried disabling safe boot, and fast boot. I have confirmed that my system has UEFI.
I believe that I once managed to run Mint off the USB but have not managed to do so since
This just happened to me, once you make the bootable USB, open it up, go into EFI/boot, and copy grubx64.efi, then rename it to mmx64.efi
Everything should work from there.
What happens if you plug the stick into another box and check it for errors
Have you tried booting directly from the BIOS and seeing it recognizes the partition? There might be a toggle for UEFI.
I recall having the image not found error last time. A mix of creating the USB with another program and tinkering with bios solved the issue. Sorry can’t be more specific, but Linux is all about tinkering, so have fun :)
