Windows 10: System recovery

I accidentally installed windows server 2012 r2 evaluation over my C drive instead of in a virtual environment. Is there a way to recover the system to before I did this? I think I may have did a clean install but I remember it saying its saved it as windows.old or something like that. All i have is the server when I boot up with the F5 function.
