I've been helping a user on IRC #ubuntu reporting this problem using the 18.10 ISO installer. In this case during the (first) installer run the PC crashed and rebooted before completing the install.
>From then on trying to boot the installer is failing with these error messages: 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 Something has gone seriously wrong: import_mok_state() failed "Failed to start MokManager" is reported by the shim's shim.c::check_mok_request(). The cause is the system's EFI NVRAM contains variable names starting "Mok*" - added by the failed installer run. As a result of theses variables being present shimx64.efi tries to load "mmx64.efi" and due to it not being in the installer's EFI system partition it fails with this report. The problem now is that there is no easy way to remove these stray variables. -- 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
