To enable virtual technology in BIOS, you'll need to restart your computer and enter the BIOS settings. This is usually done by pressing a key like F2 or Del during startup. Once you're in the BIOS settings, look for the Virtualization or VT-x option and enable it.
The process can vary depending on your computer's manufacturer and model, so you may need to do some digging to find the exact steps for your machine. But don't worry, it's still a relatively straightforward process. Just save your changes and exit the BIOS settings, and you'll be good to go!
