Step-by-Step Guide: Enabling Virtualization Support in Your System BIOS/UEFI

In the world of computing, virtualization has become a cornerstone technology that enables running multiple operating systems and software instances on a single physical machine. This guide walks you through the process of enabling virtualization support in your system’s BIOS or UEFI firmware. By doing so, you unlock the potential to run hypervisors like VMware, VirtualBox, or Hyper-V seamlessly, facilitating the creation and management of virtual machines.

Checking Virtualization Compatibility

Before diving into the BIOS/UEFI settings, it’s essential to verify if your system supports virtualization technology. Most modern CPUs come equipped with this feature, but it’s always wise to confirm. Access your system’s technical specifications or CPU documentation to ensure that hardware-assisted virtualization is present.

Accessing the BIOS/UEFI Interface

To access the BIOS/UEFI interface, restart your computer and press the designated key during the boot process. Common keys include F2, Del, Esc, or F12, depending on the manufacturer. This key press will take you to the system setup utility.

Locating Virtualization Settings

Once inside the BIOS/UEFI interface, navigate through the menus to locate the virtualization settings. These settings are often found in the “Advanced” or “Security” sections, depending on the manufacturer and BIOS version. Look for terms like “Virtualization Technology (VT-X)”, “Intel Virtualization Technology”, or “AMD-V” and ensure they are enabled.

Enabling Intel VT-x or AMD-V

Modern CPUs are equipped with either Intel VT-x or AMD-V, the hardware virtualization technologies. Enable the appropriate option based on your CPU. Once located, switch the setting from “Disabled” to “Enabled.” Remember to save the changes before exiting the BIOS/UEFI interface.

Enabling Hyper-Threading

Some systems might require you to enable Hyper-Threading to fully utilize virtualization capabilities. This feature enhances CPU performance by allowing each physical core to handle multiple tasks simultaneously. Locate the “Hyper-Threading” or “Simultaneous Multi-Threading” option and set it to “Enabled.”

Saving Changes and Rebooting

After adjusting the virtualization settings and potentially enabling Hyper-Threading, save your changes and exit the BIOS/UEFI interface. Your computer will reboot with the new settings in effect.

Verifying Virtualization Support

To ensure that virtualization support is now active, you can use system diagnostic tools or third-party software like CPU-Z. These tools will confirm whether virtualization extensions are enabled on your CPU.


Enabling virtualization support in your system’s BIOS/UEFI is a crucial step in harnessing the power of virtualization technology. This guide has walked you through the process, from checking compatibility to adjusting settings and verifying the changes. By doing so, you open the door to a world of possibilities, including running multiple operating systems, software testing, and server virtualization. Always remember that BIOS/UEFI interfaces can vary significantly, so the exact steps might differ slightly, but the underlying principles remain consistent.
