Hello, I have the same problem with my Ace aspire A515-51G, when starting by USB it can not load the mmx64.efi file. As additional information, the problem occurred in the installation, when the installer asked me to enter a password for UEFI. The system was stuck a few moments and then it was restarted, the installation was not finished. From that moment I can not see the message reported in the Bug.
The USB Live installer was created from win10 with Rufus (v3.3) -- 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
