I'm trying to do in place upgrade from server 2012 R2 to server 2016 or 2019. After installation part and after first restart I get error
The installation failed in the FIRST_BOOT phase with an error durin BOOT operation
after I click Close system is returned to Server 2012 R2.
How can I do upgrade ? Migration is not an option (server does not have any roles, just sql instance and some custom software.).
