I am trying to install opensuse leap in my laptop with secure boot on. But I cannot get the installation menu. Instead, it is stuck at grub console. Any help would be appreciated.
Unfortunately the Leap 42.1 install DVD has a shim.efi that cannot be recognized by UEFI SecureBoot.
You can disable secureboot just to complete the installation, update the new installed system online (with a new shim.efi BTW) and then re-enable secureboot to your liking.
If your BIOS doesn’t allow to disable secureboot, there might be workarounds but they might be tricky: try searching the forum or report back here…
From within the UEFI “BIOS” you may also have to increase (read maximise) the boot priority of the DVD drive being used to boot the openSUSE Leap 42.1 DVD.
