About VirtualBox Unable to select a 64-bit system, the workaround is to turn on virtualization technology in the BIOS

1. Virtualization Technology in BIOS

This article describes how to enable virtualization Technology (VT) in the motherboard BIOS. To run some operating systems, virtualization software and virtual machines, hardware virtualization needs to be enabled. In most cases, operating systems that do not require virtualization technology can function properly in systems with virtualization technology enabled, but some operating systems that require this technology must be enabled for virtualization to run.
All the latest processors and motherboards support virtualization technology, check if your motherboard vendor is supported and know how to enable or disable VT in the BIOS. When virtualization technology is enabled on the motherboard, the operating system can detect it immediately.

2. Where can I find virtualization Technology (VT) in the BIOS?

First boot into the BIOS, the general machine is press F2, my T420 is to press F1, and then enter Security,virtualization, select Enable, such as:

Different motherboard options may vary, please refer to the motherboard manufacturer's help for yourself.

After you change the settings, disable or enable virtualization, it is recommended that you turn off the computer for a minimum of 10 seconds, and then restart the machine (cold boot) to ensure that virtualization technology is turned on normally. If your motherboard is up-to-date, it detects configuration changes after a cold boot. Whenever I change the VT settings on my motherboard, it will automatically postpone the next reboot to take effect.

How do I determine if VT is turned on or off?

1) If your processor is Intel, you can use this free detection tool to verify that you have successfully turned on VT:

Intel Official Detection Tool

As shown, it means that the VT is successfully turned on:

2) AMD's processor can download this tool:

AMD Official Testing Tools

3) Microsoft has also provided a testing tool, you can also try:

Microsoft Official Testing Tools

This tool does not need to be installed and can be run directly.




Indicates that the VT is successfully turned on.
