Enabling BIOS virtualization lets hypervisors, emulators, and Windows features access your CPU’s hardware acceleration for running virtual machines.
Running a virtual machine on Windows without hardware acceleration is like driving with the parking brake on. The fix is enabling BIOS virtualization — a firmware toggle that unlocks your CPU’s full performance for Hyper-V, Android emulators, Windows Sandbox, and third-party hypervisors. The whole process takes about two minutes once you know which key to press at startup and which menu label to look for.
How to Enter Your BIOS or UEFI
The fastest way into firmware setup depends on your PC’s manufacturer, but every method lands on the same configuration screen. On Windows 11, the most reliable route is through the OS: open Settings > System > Recovery, click Restart now under Advanced startup, then navigate Troubleshoot > Advanced options > UEFI Firmware Settings > Restart. On Windows 10, the path starts at Settings > Update & Security > Recovery instead.Microsoft’s official instructions recommend knowing your device model before you start, since firmware menus and hotkeys vary by brand.
The classic startup key still works on most systems — tap it repeatedly the moment the screen lights up after powering on. The table below shows which key each major manufacturer uses.
| Manufacturer | Common Key(s) | Notes |
|---|---|---|
| Lenovo ThinkPad | F1 | Tap immediately after power — some models also use Enter then F1 |
| Lenovo IdeaPad | F2 or NOVO button | NOVO button is a small recessed button near the power port; tap it while off to get a boot menu |
| Dell | F2 | F12 opens a one-time boot menu where you can also pick BIOS Setup |
| HP | F10 or Esc | Esc shows a startup menu; then press F10 for BIOS Setup |
| ASUS | F2 or Delete | F2 on most laptops; Delete on desktop ROG and Prime boards |
| Acer | F2 | F2 on nearly all models; some older units use Delete |
| MSI | Delete | Desktop boards almost always use Delete; laptops often use F2 |
| Samsung | F2 | Most laptops use F2; a few older models use Esc |
Enabling BIOS Virtualization on Your PC: Where the Setting Hides
Once inside the UEFI or BIOS menu, the setting you need goes by several names depending on your processor and motherboard manufacturer. The most common labels are Intel Virtualization Technology (also called VT-x or Vanderpool on older Intel boards), AMD-V, SVM Mode, or simply Virtualization Technology. It usually lives under one of these tabs: Advanced, CPU Configuration, CPU Setup, System Configuration, or Security.
On many Lenovo ThinkPad systems, the option sits under Security > Virtualization. On Dell and HP business machines, check Advanced > CPU Configuration. On ASUS and MSI desktop boards, it is often under Advanced > CPU Setup. When you find the right label, highlight it, press Enter, and change the value from Disabled to Enabled.
How to Save Your Changes and Exit
Changing the value is only half the job — exiting without saving is the single most common mistake. Look for the Save & Exit tab or press the hotkey displayed on screen, usually F10. A confirmation dialog will ask whether you want to save changes; select Yes or OK. The system will then reboot with virtualization turned on.
when the PC restarts and you log back into Windows, the yellow text in Task Manager’s CPU view — described in the next section — should read “Enabled” instead of “Disabled.”
Confirm Virtualization Is Working in Windows
You can verify the setting took effect without rebooting into firmware again. Open Task Manager (press Ctrl+Shift+Esc), click the Performance tab, and select CPU on the left. Look at the bottom-right corner of the CPU view — a line labeled Virtualization will say Enabled if everything worked. If it still says Disabled, the change was not saved or the system used a different firmware setting than expected; double-check the menu path and repeat the enable-and-save steps.
If Task Manager shows Virtualization: Not available, your CPU or firmware does not expose the feature — the option may be permanently locked or genuinely absent from the hardware.
Still Can’t Find the Option?
A few systems hide the virtualization toggle deeper than expected, and some older or budget PCs simply lack it. If you have searched every tab — Advanced, Security, CPU Configuration, System Configuration, and the vendor-specific menus — and still see nothing labeled VT-x, AMD-V, SVM, or Virtualization, start by confirming whether your processor supports it. The same Performance > CPU view in Task Manager tells you: “Virtualization: Not available” means the hardware or firmware does not offer it. Some Lenovo and HP business PCs lock the setting under Security rather than Advanced, and a few Dell models place it under Performance or System Configuration.
When the option is genuinely missing, third-party hypervisors can still run — they just rely on software emulation, which is noticeably slower for demanding workloads. A lightweight Type-2 hypervisor like VirtualBox or VMware Workstation Player will still work, but expect lower performance for graphics-intensive or multi-core guest operating systems.
| Setting Label | Where It Typically Appears | Common Manufacturers |
|---|---|---|
| Intel Virtualization Technology | Advanced → CPU Configuration | Dell, HP, Lenovo, ASUS |
| VT-x | Advanced → CPU Setup | ASUS, MSI desktop boards |
| AMD-V | Advanced → CPU Configuration | HP, ASUS, Acer, Lenovo (AMD systems) |
| SVM Mode | Advanced → CPU Setup or CPU Configuration | Lenovo, Dell, MSI (AMD CPUs) |
| Virtualization Technology (generic) | Configuration or System Configuration | Most brands |
| Secure Virtual Machine (SVM) | Advanced → CPU Configuration | AMI BIOS systems, some Lenovo models |
| Intel VT-d (I/O virtualization) | Advanced or Security | Intel systems with I/O virtualization support |
Finish With the Right Windows Features Turned On
Enabling the firmware toggle alone often is not enough for Windows to use virtualization features like Hyper-V, Windows Sandbox, or Windows Subsystem for Linux. After rebooting, open the Start menu, type Windows Features, and select Turn Windows features on or off. Check the box for Virtual Machine Platform and — if you plan to use Hyper-V or Sandbox — check Windows Hypervisor Platform and Windows Sandbox as well. Click OK and restart when prompted. Microsoft’s own support page confirms that both the firmware toggle and the Windows features must be active together for the full virtualization stack to work.
That is it — BIOS virtualization enabled, verified in Task Manager, and the necessary Windows components turned on. Your system is now ready to run virtual machines, emulators, and sandboxed applications with full hardware acceleration.
