DELL T430 Server - Microsoft Windows 2012 - HYPER-V

We had just bought two DELL Server PowerEdge T430. it comes with Microsoft Windows 2012 Server Pre-install and also it came with the CDs. The CDs had no CDKEYs, they had only tracking ID.   The windows had been activated automatically..

We had add Hyper-V and create 3 Virtual Servers.  We are not able to Activate Windows Server 2012 on the Virtual Servers,

We get the error Code: 0xC004F07C

The Software Licensing Service determined that the version of the Computer BIOS is invalid.
