What you need to do is create a shortcut. Right-click a blank area on the desktop and go to New > Shortcut.

In the wizard that opens, click in the box underneath Type the location of the item, and enter the following:

Shutdown /r /fw /t 1

If you’re not familiar with these commands, /r means restart, /fw means boot to firmware (aka the BIOS) and /t introduces a delay in seconds before the restart begins. In our example above, that’s one second.

Call this new shortcut Restart to BIOS. Right-click your new shortcut on the desktop and select Properties. Click the Advanced button.

In the Properties box, tick the Run as administrator box and click on OK a couple of times to close the windows.
