WS2012 R2 will not allow install Hyper-V

Hello Community

    On one WS2012 R2 there is a Domain Controller with Active Directory, DNS and Hyper-V installed.
   
    On the other WS2012 R2 there is a member server with other software installed on it.

    The question is how can I install Hyper-V on the WS2012 R2 server when the error message says:

        Hyper-V cannot be installed because virtualization support is not enabled in the BIOS

    Thank you
