Public bug reported:
System: Lenovo ThinkPad E590
64-bit core i7 processor
UEFI
Preloaded with Win 10 booting from UEFI
Process attempted to dual-boot Ubuntu 18.04 with Windows 10;
Unable to run Ubuntu 18.04 installer from a flash key.
System gave one long beep, computer restarted.
Disabled Bitlocker under Windows
Disabled Secure Boote in UEFI
Attempted to start from flash key again,
with Ubuntu 18.04 64-bit
Received error message on black screen:
Failed to open efi\BOOT\mmx64.efi
Failed to load image efi\BOOT\mmx64.efi not found
Failed to start Mokmanager
Something has gone seriously wrong
import_mok state failed(): not found
Attempted to force boot Ubuntu 18.04 from flash drive using Supergrub
2-beta.
Supergrub message:
"Sorry but we are booted via UEFI and can not load this OS. Please try booting
SG2D via BIOS compatibility mode. Press ESC to return to main menu."
So it looks like I can't use the 18.04 installer to load Ubuntu on my
laptop under UEFI-- It may be possible to do it under Legacy/BIOS, but
then I can not have a dual-boot system.
