I upgraded Veeam B&R 9.5 from update 2 to update 3 and updated all Hyper-V host servers.
I noticed that if any Hyper-V host server get restarted, it well boot to BOSD with error NMI HARDWARE FAILURE. Whatever I do in restoring any Veeam Agent for Windows (ver. 2.0) backup, it will not solve the problem (still boot in BOSD)!
The Windows Server 2016 Hyper-V DataCenter will only boot in safe mode! I managed to uninstall Veeam B&R services along with Veeam Agent and Hyper-V role, with no success as well (still boot in BOSD)!
