Physical Windows 2016 server crashed after patching

After Patching a physical Windows 2016 server, reboot and stuck at loading screen with error "Fatal Error C0000034 Applying Update Operation".

I following many suggestions online, but nothing seems to be working.

Now the server is looping and stuck at same screen but without error code anymore.

I also tried to do an upgrade to Windows server 2019, but it won't allow me to do upgrade from iLO mount ISO, need to be able to boot into Windows to do upgrade. 

Any suggestions?

I tried to find Microsoft support number to call for help but can't find any.

Anyone know what is going on with the server? or how to fix it?
