Clé USB Tails

Félicitations, vous avez installé Tails sur votre clé USB !

Vous pouvez maintenant redémarrer votre ordinateur sur cette clé USB. Cela peut-être un peu compliqué, alors bonne chance ! Mais cela peut ne pas marcher sur votre modèle de Mac, alors bonne chance !

If you are already in Tails, go directly to step 3: Verify that the other Tails is up-to-date.

Make the computer start on the USB stick

  1. Click on the Start button.

  2. Press and hold the Shift key while you choose Power ▸ Restart.

  3. In the Choose an option screen, choose Use a device.

    If the Choose an option screen does not appear, refer to the instructions on starting Tails using the Boot Menu key.

  4. In the Use a device screen, choose Boot Menu.

    Windows shuts down, the computer restarts, and a Boot Menu appears.

    Plug in your Tails USB stick shortly after choosing Boot Menu and while Windows is shutting down.

    In the future, we We recommend that you only plug 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. See our warning on plugging Tails in untrusted systems.

    The Boot Menu is a list of possible devices to start from. The following screenshot is an example of a Boot Menu:

  5. In the Boot Menu, select your USB stick and press Enter.

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

    Black screen
    ('GNU GRUB') with Tails logo and 2 options: 'Tails' and 'Tails
    (Troubleshooting Mode)'.

    If no Boot Menu appears or if your USB stick is not listed in the Boot Menu, refer to the instructions on starting Tails using the Boot Menu key.

    Starting the computer using a Boot Menu key can be faster than starting the computer on Windows first and then on Tails. We recommend you learn how to start Tails using the Boot Menu key if you use Tails regularly.

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.

If Windows 8 or 10 is also installed on the computer, you can refer instead to the instructions on starting Tails from Windows 8 or 10. Starting Tails from Windows is easier than using the Boot Menu key.

The following screenshot is an example of a Boot Menu:

This animation summarizes how to use the Boot Menu key to start on the USB stick:

The following instructions explain in detail how to use the Boot Menu key to start on the USB stick:

  1. Éteignez l'ordinateur tout en laissant la clé USB branchée.

    Shut down the computer and plug in the Tails USB stick.

    Éteindre l'ordinateur.

    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.

  2. Identify the possible Boot Menu keys for the computer depending on the computer manufacturer in the following list:

    FabricantTouche
    AcerÉchap, F12, F9
    AsusÉchap, F8
    ClevoF7
    DellF12
    FujitsuF12, Échap
    HPF9, Échap
    LenovoF12, Novo, F8, F10
    SamsungÉchap, F12, F2
    SonyF11, Échap, F10
    ToshibaF12
    others…F12, Échap

    On many computers, a message is displayed very briefly when switching on that also explains how to get to the Boot Menu or edit the BIOS settings.

  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.

    If a Boot Menu with a list of devices appears, select your USB stick and press Enter.

    If the Boot Menu key that works on your computer is a different one than the first in the list, please let us know so we can improve the list. You can write to sajolida@pimienta.org (private email).

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

    Black screen ('GNU
GRUB') with Tails logo and 2 options: 'Tails' and 'Tails (Troubleshooting
Mode)'.

    If none of the possible Boot Menu keys from the previous technique work or if your USB stick is not listed in the Boot Menu, refer to the troubleshooting instructions about Tails not starting at all.

  1. Éteignez l'ordinateur tout en laissant la clé USB branchée.

    Branchez l'autre clé USB Tails depuis laquelle vous souhaitez réaliser l'installation.

    Écran avec
le logo d'un disque dur interne nommé 'Macintosh HD' et un disque dur
externe nommé 'Windows' (sélectionné)

    Si la clé USB n'apparaît pas dans la liste des disques de démarrage possibles :

    1. Assurez-vous que vous avez vérifié votre téléchargement de Tails.
    2. Essayez d'installer à nouveau sur la même clé USB.
    3. Essayez d'installer sur une autre clé USB.
    4. Essayez d'utiliser la même clé USB pour démarrer sur un autre ordinateur.
      Si la même clé USB fonctionne sur un autre ordinateur, merci de signaler le problème à notre centre d'assistance.
  4. Reporting the problem to our help desk

    Please send the following information to tails-support-private@boum.org:

    1. Which version of Tails are you trying to start?

    2. How did you verify the USB image?

    3. What is the brand and model of your computer?

    4. What exactly happens when trying to start? Report the complete error message that appears on the screen, if any.

    5. What program did you use to install your USB stick?

    6. Does the USB stick start successfully on other computers? If so, what are the brands and models of those computers?

    7. Have you been able to successfully start another version of Tails on this computer before? If so, which version?

  5. Si votre Mac affiche l'erreur suivante :

    Vos réglages de sécurité ne permettent pas de démarrer ce Mac depuis un disque de démarrage externe.

    Alors vous devez changer les paramètres de l'utilitaire Sécurité au démarrage de votre Mac pour autoriser le démarrage depuis Tails.

    Pour ouvrir l'utilitaire Sécurité au démarrage :

    1. Turn on your Mac, then press and hold Command(⌘)+R immediately after you see the Apple logo. Your Mac starts up from macOS Recovery.

    2. When you see the macOS Utilities window, choose Utilities ▸ Startup Security Utility from the menu bar.

    3. When you are asked to authenticate, click Enter macOS Password, then choose an administrator account and enter its password.

    Startup Security Utility

    In the Startup Security Utility:

    • Choose No Security in the Secure Boot section.

    • Choose Allow booting from external media in the External Boot.

    To still protect your Mac from starting on untrusted external media, you can set a firmware password, available on macOS Mountain Lion or later. A firmware password prevents users who do not have the password from starting up from any media other than the designated startup disk.

    If you forget your firmware password you will require an in-person service appointment with an Apple Store or Apple Authorized Service Provider.
