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

    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.
