I tried to replace Windows 10 with Ubuntu 18.04 LTS on my Lenovo T480-S via a bootable USB. The installation process went smoothly, however once it finished installing I received a notification that I needed to restart my computer. I selected the option to restart and in the process of booting back up i received an error displaying this:
Failed to open \EFI\BOOT\mx64.efi - Not found Failed to load image \EFI\BOOT\mx64.efi: Not found Failed to start MokManager: Not found Something has gone seriously wrong: import_mok_state() failed :Not found
So now i'm stuck without a working OS on my Lenovo. Windows seems to have been removed but Ubuntu will not load. I will mention that during the installation process i selected the option to install third party hardware and LVM. I'm unsure if this caused this problem..Any help would be greatly appreciated!
