I've already enabled Virtualization capabilities in the BIOS, but it still prompts me to do it.

[NEPTLIANG]

ERROR: Please Enable Virtualization capabilities in your BIOS settings...

Do you have VTx enabled from the BIOS ?

[scarycrow-dave]

I have VTx enabled in Bios, and I still get prompted, any ideas how to fix.

[sebassem]

It appears that the check for BIOS is not returning consistent results across different models , can you please share the output of both commands below in an elevated PowerShell session ?

• Get-ComputerInfo -Property HyperVRequirementVirtualizationFirmwareEnabled,hypervisorpresent
• (Get-WmiObject win32_computersystem).hypervisorpresent

[scarycrow-dave]

PS C:\WINDOWS\system32> Get-ComputerInfo -Property HyperVRequirementVirtualizationFirmwareEnabled,hypervisorpresent
HyperVRequirementVirtualizationFirmwareEnabled HyperVisorPresent

---

                                                        True

PS C:\WINDOWS\system32> (Get-WmiObject win32_computersystem).hypervisorpresent True

[Dreamer451]

I have the same issue and yes, virtualization is enabled in my BIOS. The output of the first command:

• HyperVRequirementVirtualizationFirmwareEnabled = True
• HyperVisorPresent = False

The second command results in False. This is on an HP OMEN an188nr.

@scarycrow-dave thanks for sharing the output , you should not get this message if the second output if true which is the case as you shared , one more check please to confirm that virtualization is correctly enabled on your machine . Please run the below to enable the sandbox feature and validate if it was enabled successfully or you got an error message

Enable-WindowsOptionalFeature -FeatureName 'Containers-DisposableClientVM' -All -Online -NoRestart

[scarycrow-dave]

PS C:\WINDOWS\system32> Enable-WindowsOptionalFeature -FeatureName 'Containers-DisposableClientVM' -All -Online -NoRestart

Path : Online : True RestartNeeded : False

[sebassem]

PS C:\WINDOWS\system32> Enable-WindowsOptionalFeature -FeatureName 'Containers-DisposableClientVM' -All -Online -NoRestart

Path : Online : True RestartNeeded : False

Thank you , will submit a fix shortly

The script is currently checking to see if a Hypervisor is already present. That will return True if you have Hyper-V already installed (so the computer supports virtualization). But that does not tell you if your computer supports Virtualization when it returns False.

If it returns false for hypervisor present, you'll need to check to make sure these are true so you know virtualization is supported.

Thank you , we are trying to check if virtualization is enabled or not ,VirtualizationFirmwareEnabled returns false or empty value if hypervisor is enabled

[rdjr71]

Yeah, the presence of a hypervisor changes what you get when you query the CPU. I would check for hypervisor=false, if false then do the additional 2 checks to make sure they are true.
