I was about to install Ubuntu 18.10 into laptop (MSI GT62VR 7RE Dominator Pro) using USB installation media. It was able to boot up and start installation until the installation halted with a black screen. After I rebooted I got the same error about missing mmx64.efi.
Windows 10 boots up fine without Ubuntu installation USB stick, but when I try to boot up using the stick, it fails every time giving me the same error. So I can't even start installation or use a command line from USB stick anymore. In /EFI/BOOT/ there are only BOOTx64.EFI and grubx64.efi files, mmx64.efi file is missing there (should it be there?). The installation USB stick is created in another machine, using Startup Disk Creator from Ubuntu 18.04. Thank you for fixing grub2! How can I use patched grub2 and create a new Ubuntu installation USB stick which would work? Or what should I do? -- 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
