I have a problem booting into Ubuntu 18.04. Before this I had Ubuntu 16.04, then I installed Ubuntu 18.04 and got this error.
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
System BootOrder not found. Initializing defaults.
Create boot entry "Boot0000" with label "ubuntu" for file "\EFI\ubuntu\shimx64"
Reset System
Then I tried to install Ubuntu 16.04 back and got the same error. After that I freed my disk (by setting all disk space to zero, formatting) and reinstalled Ubuntu, but I got the same error. Afterwards I installed Boot-Repair and reinstalled grub, but nothing changed. I have a Sony VAIO SVP112A1CV notebook. GPT was made by Rufus and tried it by running the dd
command in Linux.
