How to enable virtualization in BIOS: Intel VT-x and AMD SVM
Enable virtualization in the BIOS of ASUS, MSI, Gigabyte and ASRock boards and laptops: Intel VT-x and AMD SVM. How to check it and why Hyper-V gets in the way.
- Virtualization is a CPU feature: Intel calls it VT-x, AMD calls it SVM. You turn it on in the BIOS.
- To check: Task Manager → Performance → CPU → the “Virtualization” line.
- In the BIOS it sits in the CPU settings: Advanced → CPU Configuration, OC on MSI, Tweaker on Gigabyte.
- A loader needs virtualization on and Hyper-V off: otherwise the Windows hypervisor grabs it first.

An Android emulator says “enable virtualization”, a loader quits with a VT-x error, and the product instructions list “Intel VT-x / AMD SVM: enabled”. It’s all the same CPU setting, and you turn it on in the BIOS in a couple of minutes.
What virtualization is and why you need it
Hardware virtualization is a CPU feature: Intel calls it VT-x (Intel Virtualization Technology), AMD calls it SVM or AMD-V. It lets a program start its own small hypervisor — a layer that runs below Windows.
Android emulators, virtual machines and some loaders and spoofers rely on it. Having it on doesn’t affect game performance, and it isn’t dangerous: it’s an ordinary feature that many PCs ship with enabled.
The confusion starts with Hyper-V. That’s Windows’ own hypervisor, and it runs on virtualization too. When it’s running, it takes virtualization for itself, and the loader gets refused.
- BIOS: VT-x / SVM turn on
- Windows: Hyper-V and Core Isolation —turn off
- Loader gets virtualization
How to check whether virtualization is on
- Open Task Manager: Ctrl + Shift + Esc.
- Go to Performance → CPU.
- Find the Virtualization line at the bottom right. If it says “Enabled”, there’s nothing to change in the BIOS.
If it says “Disabled”, virtualization is turned on in the BIOS.
How to get into the BIOS
The easiest way is from Windows: Settings → System → Recovery → Advanced startup → Restart now, then Troubleshoot → Advanced options → UEFI Firmware Settings.
Or press the setup key right after power-on: on ASUS, MSI, Gigabyte and ASRock it’s usually Del, on laptops F2, on HP Esc and then F10. The full key table is in the article about Secure Boot.
Where virtualization lives in each maker’s BIOS
First switch the BIOS to advanced mode: on ASUS and MSI that’s F7. The option has different names on Intel and AMD.
| Maker | Intel | AMD |
|---|---|---|
| ASUS | Advanced → CPU Configuration → Intel Virtualization Technology | Advanced → CPU Configuration → SVM Mode |
| MSI | OC → CPU Features → Intel Virtualization Tech | OC → Advanced CPU Configuration → SVM Mode |
| Gigabyte, Aorus | Tweaker → Advanced CPU Settings → Intel Virtualization Technology | Tweaker → Advanced CPU Settings → SVM Mode |
| ASRock | Advanced → CPU Configuration → Intel Virtualization Technology | Advanced → CPU Configuration → SVM Mode |
| HP (laptops) | Advanced → System Options → Virtualization Technology | same |
| Lenovo (laptops) | Configuration → Intel Virtualization Technology | Configuration → AMD SVM Technology |
| Dell | Virtualization Support → Enable Intel Virtualization Technology | same |
Set it to Enabled, press F10 and confirm saving. Once Windows loads, check the Virtualization line in Task Manager again.
It’s on, but the loader still complains
Most often Hyper-V is holding virtualization. The check is simple: run systeminfo in a command prompt. If the very end says “A hypervisor has been detected”, the Windows hypervisor is running.
You turn it off through Windows features and the bcdedit /set hypervisorlaunchtype off command. Step by step, together with Core Isolation, which also turns it on, it’s covered in the article about Core Isolation and Hyper-V.
The option is missing or greyed out
- The laptop hides the setting. On some Acer and HP models the Advanced section only opens after you set a BIOS administrator password (Supervisor Password).
- An old BIOS version. Update the BIOS from the board maker’s site: in newer versions the option sometimes moves to another section.
- The CPU doesn’t support it. That only happens with very old or the cheapest models. Check your CPU model on Intel’s or AMD’s site.
Before the first loader launch, check the other settings too: Defender, Secure Boot and Core Isolation. The checker shows all of it in half a minute:
FAQ
Yes. It’s an ordinary CPU feature, and many PCs ship with it enabled. It doesn’t affect in-game FPS.
Virtualization (VT-x, SVM) is a CPU capability you enable in the BIOS. Hyper-V is the Windows hypervisor that uses that capability. For a loader you turn the first on and the second off.
Switch the BIOS to advanced mode (F7 on ASUS and MSI), look in the CPU section, and update the BIOS. On Acer and HP laptops the section sometimes opens only after you set a BIOS administrator password.
The setting didn’t save. Go into the BIOS again, set it to Enabled and save with F10. On some boards a full shutdown helps instead of a restart.
