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..   Loading /bzimage....ok Loading /bzroot..._   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)
