How to enable VT-x in OS on 13th gen NITRO V15 i5?

🔧 VT-x Not Enabled Even After Activating in BIOS (Acer Nitro V15 - i5 13420H)

Hi everyone,

I'm experiencing an issue where VT-x (Intel Virtualization Technology) remains disabled in Windows, even though it's clearly enabled in the BIOS. I'm using a Nitro V15 with an Intel Core i5-13420H (13th Gen), and I’ve already confirmed the CPU supports VT-x.

The tool LeoMoon CPU-V shows:

✅ VT-x Supported
❌ VT-x Enabled

I’ve done the following steps:

✅ BIOS Check

Enabled Intel Virtualization Technology (VT-x) in the BIOS.
Saved and exited BIOS (even toggled off → reboot → on → reboot again).

✅ Disable Hypervisor on Windows

Ran the following command as Administrator in Command Prompt:

bcdedit /set hypervisorlaunchtype off

Then restarted the computer.

Confirmed via bcdedit that:

hypervisorlaunchtype      Off

✅ Disabled Optional Features

Went to "Turn Windows features on or off" and unchecked:

Hyper-V
Virtual Machine Platform
Windows Hypervisor Platform
Windows Subsystem for Linux

Then rebooted.

✅ Disabled Virtualization-Based Security (VBS)

Opened Settings > Privacy & Security > Windows Security > Device Security
Clicked Core Isolation Details
Turned off Memory Integrity
Restarted the PC

✅ Checked System Info

Opened msinfo32 and saw this line:

"A hypervisor has been detected. Features required for Hyper-V will not be displayed."

That means the Windows Hypervisor was still active earlier — but now, after the above steps, this message should be gone.

❌ Problem Remains

Despite all of the above, LeoMoon still shows:

❌ VT-x is not enabled

❓Question

What else can be preventing VT-x from being activated, even after disabling Hyper-V and enabling virtualization in BIOS?

Any help would be greatly appreciated!

Thanks!

Welcome @miking,

Check that the firmware of your Nitro V15 is updated with the latest available version (1.26 or higher):

It's in 1.26

If you have VTX enabled in bios even if the settings doesn't set, and you have the last bios version 1.26 installed on your Nitro ANV15-51 then install a Virtual Box software and see if it installs and works, as that is all that the VTX setting in bios enables which is virtualisation.

To enable VT-x in the operating system on an Acer NITRO V15 with a 13th gen processor, you'll need to enable it in the BIOS/UEFI settings. This process generally involves restarting your computer, entering the BIOS/UEFI setup during boot, navigating to the relevant settings (usually under Advanced or CPU Configuration), finding the virtualization option (Intel VT-x or AMD-V), and enabling it.

Here's a more detailed breakdown:
1. Restart your computer:
Power off and then power on your Nitro V15.
2. Enter BIOS/UEFI:
During the boot process, press the appropriate key (usually F2, F10, Delete, or ESC) to enter the BIOS/UEFI setup. This key may vary depending on the Nitro V15 model, so consult your laptop's manual or search online for specific instructions.
3. Navigate to Advanced/CPU Configuration:
Use the arrow keys to navigate to the Advanced settings, System Configuration, or CPU Configuration menu.
4. Locate Virtualization Technology:
Within the Advanced/CPU Configuration menu, find the option for Intel Virtualization Technology (VT-x), AMD-V, or a similar term.
5. Enable Virtualization:
Select the virtualization option and enable it (usually by pressing Enter and selecting Enabled).
6. Save Changes and Reboot:
Save the changes you made in the BIOS/UEFI settings (often by pressing F10, selecting "Save and Exit," or similar) and allow the system to reboot.
Important notes:
Check your specific model:
The exact BIOS/UEFI interface and naming conventions for virtualization options may vary slightly depending on the Nitro V15 model. Consult your laptop's manual or Acer's support website for specific instructions.
AMD-V (for AMD processors):
If your Nitro V15 has an AMD processor, look for the AMD-V option instead of Intel VT-x.
After enabling:
Once VT-x is enabled in the BIOS, you can verify that it is also enabled in your operating system by using the sysdm.cpl command prompt.
