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. ** Affects: syslinux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866152 Title: UEFI prevents live version from loading 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/syslinux/+bug/1866152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
