Same problem: Initial boot from Ubuntu 18.10 USB worked but the installation crashed while I was inputting information (black screen). Was then able to boot from Windows 10 USB stick and install. Windows works fine. But still not able to boot from Ubuntu USB with message:
Failed to open \EFI\BOOT\mmx64.efi - Not Found Failed to load image \EFI\BOOT\mmx64.efi: Not Found Failed to start MokManager: Not Found Somethinghas gone seriously wrong: import_mok_state() failed : Not Found Tried both secure and not secure boot. I am not an expert so I am lost at this point. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798171 Title: System fails to boot with \EFI\BOOT\mmx64.efi - Not Found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1798171/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
