18.10bootdelldual-bootuefi
I tried to install Ubuntu 18.10 on my XPS 15 9570 earlier. Everything was working fine until I got to the partition selection part of the installation. That’s when the installer crashed and I had to shut down my machine. I think it’s because I had my SATA configuration set to RAID ON instead of AHCI, which is now fixed.
Now when I try to run the installer from my bootable USB I get the following error
Failed to open EFIBOOTmmx64.efi - Not Found
Failed to load image EFIBOOTmmx64.efi: Not Found
Failed to start MokManager: Not Fond
Something has gone seriously wrong: import_mok_state() failed
Hoping someone might have some idea as to what is going on
Accepted Answer
I booted an Ubuntu Live USB stick, went into my hard disk drive’s /boot/efi folder and renamed the file grubx64.efi to mmx64.efi
Reboot the machine and it should work.
