Welcome to Android Central! Which device? On that screen, you usually need to do a combination button press, like pressing and holding the Vol Down button, then tapping the Power button. But if you tell us your device, we might be able to find the specific instructions for you.

Are you unable to boot up normally, then go to Settings>Backup & Reset​, and select Factory Data Reset from there?
