Tails USB stick

Congratulations, you have installed Tails on your USB stick!

You will now restart your computer on this USB stick. It can be a bit complicated, so good luck! But it might not work on your Mac model, so good luck!

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 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. 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)'.

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. Shut down the computer while leaving the USB stick plugged in.

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

    Shut down the computer.

    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:

    ManufacturerKey
    AcerF12, F9, F2, Esc
    AppleOption
    AsusEsc
    ClevoF7
    DellF12

    MSIF11
    SamsungEsc, F12, F2
    SonyF11, Esc, F10
    ToshibaF12
    others…F12, Esc

    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.

  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)'.

  1. Shut down the computer while leaving the USB stick plugged in.

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

  2. Switch on the computer and immediately press-and-hold the Option key (Alt key) until a list of possible startup disks appears.

'alt' key in the bottom left of Mac keyboard

  3. Choose the USB stick and press Enter. The USB stick appears as an external hard disk and might be labeled EFI Boot or Windows like in the following screenshot:

    Screen
with the logo of an internal hard disk labeled 'Macintosh HD' and an
external hard disk labelled 'Windows' (selected)

    If the USB stick does not appear in the list of startup disks:

    1. Make sure that you have verified your download of Tails.
    2. Try installing again on the same USB stick.
    3. Try installing on a different USB stick.
    4. Try using the same USB stick to start on a different computer.

    If your computer still does not display the Boot Loader, it might currently be impossible to start Tails on your computer.

  4. If your Mac displays the following error:

    Security settings do not allow this Mac to use an external startup disk.

    Then you have to change the settings of the Startup Security Utility of your Mac to authorize starting from Tails.

    To open Startup Security Utility:

    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.

Troubleshooting
