In a too passionated attempt to boot Ventoy in secure boot mode. I restored factory keys in the BIOS.
Now when i boot TOS in secure boot mode i get the message:
"Secure Boot Violation"
Invlid signature detected. Check Secure Boot Policy in Setup.
So i have to disable Secure Boot to load TOS
Can anybody export secure boot variables and load them up.
Or does anybody knows if it's save to follow the steps on a F4-424 mentioned in this tread.

I had the same problem after testing unraid on my terramaster F8.
To install unraid I deactivated the following:
Vt-d
Secure boot
Boot TOS first
After I finished testing unraid, I then reactivated everything and put back the original usb disk with the TOS system.

Here is when the secure boot violation came up.

Restoring default setting in the bios did not work.
Restore factory keys ( after having removed the usb disk otherwise these settings stay grey and cannot be changed) did not work either.
There are other option like reset to setup mode and key management, but I would like to not mess things further.

Any help or insight will be appreciated.

Select Linux distributions do support Secure Boot, unRAID is currently not one of them.

You will need to keep it disabled to have a successful boot.

I installed a minimal version of Debian and on top of that Openmediavault. Now i can enable secureboot.
Here is an how to for 64bit and 32bit OS. https://wiki.omv-extras.org/doku.php?id ... it_install
It's the only way to safely use your brand new device.
I have contacted Terramaster but there advise is of no use.
