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

[deeegy]

Hello--
thank you to all those who took time to comment and provide strategies to this problem.

I'd like to thank several of the posters here, poster #57's idea solved
the prolem for me.

#I was trying to install 18.04 LTS through USB;
#there was a previous install, and I wanted to keep the files.
#Mid way through 18.04 install, computer crashed

I then had the same problem that was seen in this thread; downloading
and booting into 19.04 proved to be the solution. Installation proceeded
as normal.

must be a bug with 18.04?

Thank you again, and good luck.


I was able to keep my files. plan is to back up and fresh install ubuntu. Don't be like me :/ (back up everything)
