    ************************************************** ***********

    Hi all,
    I would like to run a virtual machine on my windows 8.1.
    What I did:
    BIOS:
    When activating VT-d, save&exit, power off, power on,
    Windows:
    login to windows, control panel, add programs and features, activate or deactivate windows features, navigating to hyper-v, hyper-v platform is still greyed out. Virtualbox as well as VMware are reporting, that VT-d is not activated in the firmware.

    Anybody can help?

    Best regards
    Connor

    added info:
    BIOS 1.9,
    Windows 8.1 64-bit,
    Intel Core i7-5820k
