I recently move to a new town. Before leaving I shutdown my Unraid server and took the USB drive out for safe keeping. When I got to my new location I put the USB drive back into the machine and if would not boot up. I plugged in a monitor and keyboard to see what was going on and upon boot up, an error message of "selected boot image did not authenticate" comes up no matter what I do to the boot settings in the bios. It worked just fine before I moved, but now I can't get the OS to fire up. I do not have a copy of the USB drive made. I didn't think about it until this happened and I started reading the materials for what to do when this happens.
So my question is, what I can do now to get my Unraid OS to work on my machine. Has anyone run into this? Is there a simple fix to keeping my key, my settings, and my configurations. I don't know if there are some files that I can save off of the USB drive to another computer, then flash the drive and reinstall a new version of Unraid and then place the old key, settings and configuration files back into the folders?
Any help would be greatly appreciated.
