I am trying to install a copy of Windows Server 2012 on two machines. Both machines go through the initial "Files loading" progress bar and get to the new Windows Server 2012 logo. However, the installation (on both machines) will immediately fail, and the machine will restart. I am trying to figure out if there's a way to display diagnostic information about the error before or after restarting, but Google is not helping me at all. Is there a key combination I can hit that will display an error log, perhaps?
