Most computers do not start on the Tails USB stick automatically but you can press a Boot Menu key to display a list of possible devices to start from.

Si Windows 8 ou 10 est aussi installé sur l'ordinateur, vous devez suivre plutôt les instructions pour démarrer Tails depuis Windows 8 ou 10. Démarrer Tails depuis Windows est plus facile qu'en passant par le menu de Boot du BIOS.

The following screenshot is an example of a Boot Menu:

    Plug in the other Tails USB stick that you want to install upgrade from.

    Unplug your Tails USB stick while leaving the intermediary USB stick plugged in.

  3. Switch on the computer and immediately press several times the first possible Boot Menu key identified in step 2.

  4. If the computer starts on another operating system or returns an error message, shut down the computer again and repeat step 3 for all the possible Boot Menu keys identified in step 2.

  5. If the computer starts on Tails, the Boot Loader appears and Tails starts automatically after 4 seconds.
