[Bug 1798171] Re: System fails to boot with \EFI\BOOT\mmx64.efi - Not Found

[Max Gaukler]

Would it be possible to backport the fix from 19.04 to 18.04 LTS? The
bug is quite difficult to work around, and easy to trigger - just abort
the setup some time after checking the third-party-drivers box.


For anyone who still needs a workaround for 18.04, because you for some reason don't want to install a newer version:

I am assuming you are installing Ubuntu from a USB stick, which was created from the dowloaded ISO file.
The problem with most previous suggested workarounds is that the stick shows up "read-only" because of the iso9660 filesystem), so you can't just copy the file as suggested.

Use a second USB stick, format it with GPT partition table and FAT32 filesystem.
Copy the folder <Ubuntu install stick>/EFI to <your new stick>/EFI.
Copy <your new stick>/EFI/grubx64.efi to <your new stick>/EFI/mmx64.efi
Plug both sticks into the PC to be installed, boot from the new stick.
Now you are in the GRUB bootloader, but on the "new" stick which is missing the rest of the Ubuntu setup files.
Press c (commandline)
set root=(hd1)
Note: (hd1) is the "old" Ubuntu install stick. In your system, the number may be different, e.g. (hd2). Press "Tab" twice to see information about the drive; the right one will show up as "Ubuntu 18.04"
Press Enter, Press ESC
Select "Install ubuntu". Install ubuntu as usual.
