Win Server 12 installation

After installlation always I get this message and it does not move forward…what to do?

Windows server 2012 allows you to switch between core version and GUI version, I think you installed the core version where you don’t get a GUI. You can look at this link to get the GUI https://www.prajwaldesai.com/switching-between-gui-and-server-core-in-windows-server-2012/
