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

    What I would do:

    Wipe USB stick.

    Recreate Partition table and partition on USB.

    Check Mint image integrity.

    Rewrite USB with image.

    Try booting from it again.

      Recreate Partition table and partition on USB. Hm… this is interesting. What is this step? I didn’t see it in the installation guide, i believe…

        I don’t know about any guide I can point to, but you can start over on the USB stick by recreating the partition table (msdos) and partition (fat32). I recommend using gparted for things like that if you are unfamiliar with the process. This ensures the USB is correctly setup to boot from.

        the USB might not have had a partitiin table to begin with. it’s not required for them. the file system can be directly on it and often is. however, when you made it into a bootable using an image, it would create a table if the image requires it.
