Hi Community,

when you install Microsoft Hyper-V role on a new system, it could be that you get the error and you can't install Hyper-V. Mostly the error says that your CPU don't support virtualisation technology.

Error Windows Server 2012

Error Windows Server 2008 and 2008 R2

In nearly all of the cases the issue is that Intel VT or AMD-V is disabled in BIOS or UEFI. To fix this, you should restart your system and enter the BIOS or UEFI. Mostly you find the options in processor settings. You only have to enable it and than you can install the Hyper-V role. For Windows Server 2012 you have also to enable the executional bit (NX-Bit). See some example BIOS and UEFI settings.
