I had a 2008 R2 Standard Server which I upgraded to Server 2012 Standard. I had Hyper-V installed and I'm happy to report the upgrade process was pretty easy. After the install we wanted to try managing the server as a Server Core Install. I ran the Power Shell command: uninstall-windowsfeature server-gui-mgmt-infra which removed the full GUI as well as the minimal server install.
We are trying to add the Minimal GUI or Full Gui back and we get an error message after reboot.
The server reboots and the sever is back to it's core status.
I've also tried to remove the binaries, uninstall-windowsfeature server-gui-mgmt-infra -remove and then re-add them with install-windowsfeature server-gui-mgmt-infra -source wim:e:\sources\install.wim:2 but get the same error.
Allowing it to download them from the Internet also give the same error.
For additional troubleshooting I did a Windows Server Backup and restored to a lab environment. I installed 2012 core on top which installed fine but when I try to add the GUI again I get the same errors.
Server logs are no help and I'm running out of options.
