We just bought a new server that<br>supports the Conroe CPU model, and I am trying to install Server 2012 R2<br>without luck. I keep getting error code 0x000000C4. The problem is while<br>Windows is still to load into its pre-installation environment it cashes<br>and then immediately resets. This is a continuous loop. I have found a way<br>to install Server 2012 R2. Move the cluster away from the Conroe Family (in<br>my case Penryn).
