Sneaky guy You owe us all a rep @Brink despite the forum rules

FWIW, this is what you get if you try to boot from a thumb drive that has any part of the boot files that do not pass the security integrity check of Secure Boot. For this I used a very common Boot Media, my Macrium Rescue thumb drive. It's only a few days old. Apparently, MR has an unsigned or mis-signed element somewhere in the Rescue Media build. The same MR will boot fine from the MS Boot Manager Menu with Secure Boot enabled, just not the thumb drive.

Very interesting TC .... My Ventoy USB with MR ISO doesn't have this nasty issue: Ventoy iso bootloader EASY installs from usb for any iso os file

If you've never tried Ventoy, it's highly worth a taste IMHO.

Now that's interesting - for Macrium!
What settings on the Bootable Media did you use?

Is it a known issue?

Just the standard MR build option, nothing fancy.

Is it a known issue? I've not heard or seen it discussed before, so it may not even be an issue, in that sense. If I have to boot the thumb, I disable SC.

All this may be getting a bit too far OT.
