I have a problem to boot from the usb live x86_64 KDE opensuse-Leap 15.3 download from “https://get.opensuse.org/leap”.
Because I would like to first check that can Leap 15.3 run on my laptop with NVIDA graphic card,
I booted from this live version and installed the official NVIDIA driver using the “easy way” mentioned here “https://en.opensuse.org/SDB:NVIDIA_drivers”.
After the first reboot, the NVIDIA driver was not load. I though there probably be the issue caused related to the secureboot.
So I ran
# mokutil --import /var/lib/nvidia-pubkeys/MOK-nvidia-gfxG0<X>-<driver_version>-<kernel_flavor>.der --root-pw
And then it came something broken with the boot loader!!
Failed to open \EFI\BOOT\MokManager.efi - Not Found Failed to load image \EFI\BOOT\MokManager.efi: Not Found Failed to start MokManager: Not Found Something has gone seriously wrong: import_mok_state() failed : Not found
Because it was just boot from live-usb.
So I cleaned up and rebuilt the live usb for Leap15.3.
After reboot, it still persists the same boot error.
I have checked this thread “update killed bootloader”, and learned that a workaround is to copy MokManager.efi to \EFI\Boot.
But I can not find where the MokManager.efi it is…
Any suggestions/ideals ?
By the way, win 10 is the only operation system on this laptop and is running well with no problem.
Thank you for reading this~~
