Hello. I’ve been trying to get secure boot/disk encryption working on my balena x86 devices. It seems the os installs but as soon as it reboots I get a Secure Boot Violation. How do I debug this?

Looks like the OS doesn’t actually get installed. Half the time I try to install it I just get a black screen and nothing seems to happen. Sometimes it reboots with this error but the OS was never actually installed.

Hi @pinter,

The suggestions that I put in your another thread may be helpful here.

Also, you can use the BIOS to check if the balena keys were enrolled. Not all BIOSes will show you which keys are enrolled, but most will. On the first reboot after provisioning with secure boot, go directly to the BIOS. You should see something like this:

Hi thank you. The best solution was to physically reset the BIOS back to factory and then installation works great.
