    Most computers do not start on Tails by default. If it does you are lucky. Otherwise, if the computer starts on Debian, Ubuntu, or Linux Mint Windows, Linux, Windows or Linux, refer to the troubleshooting section about Tails not starting at all.

    Troubleshooting: Tails does not start at all

    The following section applies if the Boot Loader Menu does not appear when starting on a USB stick.

    It is quite common for computers not to start automatically on a USB stick with Tails installed. Here are some troubleshooting techniques. You should try them one after the other.

    Getting to the boot menu

    On most computers, you can press a boot menu key to display a list of possible devices to start from. The following instructions explain how to display the boot menu and start on the USB stick. The following screenshot is an example of such boot menu:

    1. Shut down the computer.

    2. Make sure that the first USB stick is plugged in the computer.

    3. Identify the potential boot menu keys for the computer depending on the computer manufacturer in the following list:

      ManufacturerKey
      AcerEsc, F12, F9
      AsusEsc, F8
      DellF12
      FujitsuF12, Esc
      HPEsc, F9
      LenovoF12, Novo, F8, F10
      SamsungEsc, F12, F2
      SonyF11, Esc, F10
      ToshibaF12
      others…F12, Esc
    4. Riaccendi il computer.

      Immediately press several times the first potential boot menu key identified in step 3.

      1. If a boot menu with a list of devices appears, select your USB stick and press Enter.

      2. If the computer starts on another operating system, then:

        1. Shut down the computer.

        2. Press-and-hold the potential boot menu key identified in step 3.

        3. Switch on the computer again while holding the potential boot menu key pressed.

          1. If a boot menu with a list of devices appears, select your USB stick and press Enter.

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

    If none of the potential boot menu keys identified in step 3 work or if the USB stick does not appear in the list, then try the second troubleshooting technique described below.

    Check our list of known issues

    Similar problems might have been reported already for your model of computer in our list of known issues.

    Edit the BIOS settings

    You might need to edit the BIOS settings of the computer.

    Search for the user manual of the computer on the website of its manufacturer to learn how to edit the BIOS settings:

    In the BIOS settings, try to apply the following changes one by one and restart the computer after each change. Some changes might not apply to certain computer models.

    Take note of the changes that you apply to the BIOS settings, to be able to revert them if they prevent the computer to start on its usual operating system.

    1. Edit the Boot Order. Depending on the computer model you might see an entry for removable devices or USB media. Move this entry to the top of the list to force the computer to try to start from the first USB stick before starting from the internal hard disk.

    2. Disable Fast boot.

    3. If the computer is configured to start with legacy BIOS, try to configure it to start with UEFI. Else, if the computer is configured to start with UEFI, try to configure it to start with legacy BIOS. To do so, try any of the following options if available:

    4. Try to upgrade the BIOS to the latest version provided by the manufacturer.

      • Tails Installer, or
      • dd on the command line?

      Note that these are the only supported installation methods.

    6. Have you been able to start Tails successfully on this computer before, from another USB stick or DVD, or with another version of Tails? If so, which ones?

    7. Does the same USB stick start successfully on other computers?

    If your computer fails to start on the USB stick, then it might currently be impossible to start Tails on your Mac model.

  4. Dopo 30–60 secondi, un altro schermo chiamato Tails Greeter compare.

    If the computer display the error message Error starting GDM with your graphics card, refer to our list of known issues with graphics cards.

    If the computer stops responding or displays other error messages before getting to Tails Greeter, refer to the troubleshooting section about Tails not starting entirely.

    Risoluzione dei problemi

    Tails non si avvia

    The following section applies if the Boot Loader Menu appears but not Tails Greeter when starting Tails.

    1. Riavvia il computer sulla prima chiave USB.

    2. In the Boot Loader Menu, choose the Troubleshooting Mode which might work better on some computers.

    3. If the Troubleshooting Mode does not work better, restart the computer again on the first USB stick.

    4. In the Boot Loader Menu, press TAB. A command line with a list of boot options appears at the bottom of the screen.

    5. Premi il tasto Backspace molte volte per rimuovere l'opzione quiet dalla linea di comando.

    6. If Tails previously failed to start and displayed the Probing EDD (edd=off to disable)... error, then type edd=off to add this option to the command line.

    7. Digita 'debug nosplash' per aggiungere queste opzioni alla riga di comando.

    8. Per avviare Tails, premi Invio.

    9. Dei messaggi d'errore dovrebbero ora apparire all'avvio di Tails. Puoi inviarli al nostro team di supporto via email, per esempio facendo una foto all'ultima schermata e messaggio d'errore.

    10. Se il messaggio d'errore è /bin/sh: can't access tty; job control turned off seguito da (initramfs), prova a rimuovere l'opzione live-media=removable dalla riga di comando d'avvio.

      Se rimuovere live-media=removable ti consente di avviare Tails, per favore riporta il problema al nostro team di supporto. Questo contribuisce a migliorare la lista delle chiavi USB problematiche. Quindi prova a installare da un'altra chiave USB.

    Rimuovere l'opzione live-media=removable potrebbe essere pericoloso. Se un avverario ha avuto accesso al computer e ha installato una Tails malevola su un hard disk interno, il computer potrebbe avviarsi sulla Tails malevola invece che sulla chiave USB.

  5. In Tails Greeter, select your language and keyboard layout in the Language & Region section. Click Start Tails.

  6. Dopo 15–30 secondi, ti apparirà il Desktop di Tails.
