Basically after I add the role in the server manager and restart for the first time, the progress bar fills and after that I'm informed that installation failed and that computer is reverting the process. After that it reboots by itself and one progress bar later I can log in. After that I'm taken back to the server manager which shows me the exact same screen which I had before the restart.
After several cycles, the server manager won't start and I can leave the loop, but that doesn't solve my problem with Hyper-V installation.
And if it matters, yes I have hardware support for virtualization and it works fine in other virtual machines.
