Enabling processor virtualization using the BIOS is actually quite simple. Most modern computers should have this option, so there is a good chance that yours has it to. And it will take only few minutes to set it up.
To boot into BIOS, you will need to restart your computer, so make sure that all of your work is saved in the apps you are currently using, and all of them are closed. Restart your computer, and you will see the BIOS screen before the Windows loading screen. You will need to hit the activator key, which in most cases is F2, F5, or F12.
You should see a very basic screen with a blue background and limited list of options to choose from. Most commonly those are Boot, Power Management, Advanced BIOS etc. Search for options that mention virtualization. It should be under Processor, Advanced CPU config. If you don’t see virtualization just click through each menu item and try to find it within your options. Look for terms like Virtualization Extensions, Intel VT-x or VT-x. If you find it you should be able to toggle it on/off or enabled/disabled by pressing Enter.
After you are sure that you have enabled virtualization save your settings and quit BIOS. Your computer will restart with its virtualization option enabled in normal mode.
