Hyper-V cannot be installed because virtualization support is not enabled in the BIOS - VM Gen2

Question

Hi,

I'm trying to enable the HYPER-V role for a Gen2 VM, in order to deploy an azure stack HCI cluster.

However from Windows admin center does not allow me to install the role.

I try to do it directly from the vm but it tells me the following message**: Hyper-V cannot be installed because virtualization support is not enabled in the BIOS .**

The VM where I have installed the HCI operating system is generation 2, I understand that Genration 2 works with UEFI and Generation 1 with BIOS.

Any recommendation you can offer me. Thank you

Only specific VM sizes are capable of running nested virtualization. Those that support it will be found on this page and are marked with ***. Here is a current list of VMs that support it:

• D_v3
• Ds_v3
• Dv4
• Dsv4
• Ddv4
• Ddsv4
• E_v3
• Es_v3
• Ev4
• Esv4
• Edv4
• Edsv4
• F2s_v2 – F72s_v2
• FX4 – FX48
• M
• Mv2

Hope this helps. Let me know if you have further questions or run into any issues.
