Unable to boot installation USB drive either with Secure Boot enabled or disabled

Hi!

I am not able to boot the openSUSE LEAP 42.1 installation USB drive either with Secure Boot enabled or disabled.
With secure boot enabled, I get the following error message:

With secure boot disabled, I get MokManager error message from GRUB.
The openSUSE 42.1 installation USB drive was created by SUSE Studio ImageWriter.
Is there any suggestions?
By the way, isn’t openSUSE 42.1 already signed? Why would it encounter the Secure Boot issue in the first place?

Thanks!

It is signed so first check the check sums of the ISO you downloaded.

Also you need to be sure you boot the installer in EFI mode and not legacy mode.

I have checked the SHA256 checksum of the downloaded ISO file, it is correct.
Yes, the system was boot in the EFI Mode.

Unfortunately, there are some bugs that crept into EFI support with 42.1. There should be an update soon, but that’s too late for the install iso. Whether the bugs affect you, depends on your system firmware.

The bugs should not be a problem with secure-boot disabled. So I’m not sure what went wrong there. Was there any error message in that case?

Yes. There was an error message related to MokManager, but I can’t remember the whole sentence.
I will boot again and note down the error message later.

This is the error message displayed while booting the installer with Secure Boot disabled:


I have waited for a few minutes, but the message stays there.
Also, the LED indicator light on the USB Drive did not blink at all after the error message was displayed.

I have not come across that.

It is probably saying that there’s a problem with the way that NVRAM is structured. But I’m just guessing.
