> In ubuntu 18.04 you need to select it manually while booting up. Yes, user can select UEFI mode or BIOS at boot time of installation, but somehow UEFI mode installation of opensuse (thumbleweed) works fine, but 1804 is not (on same disk and machine).
Also UEFI mode installation 1804 on that machine displays "message" what it will be "manufactered mode" (as i remembered) and incorrectly defines (displays in partition table) all existing ext4 partition as "efi", and cant install grub on /dev/sdf(1), but tried on /dev/sda with failure message. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767703 Title: Calling 'apt-install grub-efi-amd64-signed' failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1767703/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
