If the <strong>Choose an option</strong> screen or the <strong>Use a device</strong> option don't appear, refer to the [[instructions on starting Tails using the Boot Menu key|doc/first_steps/start/pc#boot-menu-key]].
If your Windows has no <b>Boot Menu</b> option available, make sure that your <span class="upgrade">intermediary</span> Tails USB stick is plugged in and choose your USB stick directly in the list of devices.
<span class="windows upgrade-windows">In the future, we</span><span class="standalone">We</span> recommend that you only plug in your Tails USB stick while Windows is shutting down. Otherwise, a virus in Windows could infect your Tails USB stick and break its security.
Such an attack is possible in theory but very unlikely in practice. We don't know of any virus capable of infecting Tails.<span class="standalone">See our [[warning on plugging Tails in untrusted systems|doc/about/warnings/computer#software]].</span>
