After making sure my 6.8.3 was stable I made a dumb decision to update to 6.9.2
After updating and rebooting the server the Unraid started..
then black screen, beep... BIOS logo and infinite loop from there.
I pulled the USB and moved all the files from the backup folder to root of the USB overwriting the 6.9.2
Booting up I was able to get into the OS without issues.
Once back in OS (6.8.3)
