There are three methods you can use: use the first option if you don't have a chance when booting the computer to mash any buttons to enter any menus, use the second option if your computer doesn't boot into windows immediately and allows you to mash a button to enter a menu, and use the third option if you're running Windows through Boot Camp on a Mac.
