This page describes the basic and advanced techniques to start Tails from a USB stick on PC.

Starting from Windows 8 or 10

From Windows or the sign-in screen of Windows:

  1. Make sure that you have installed Tails using either:

  2. Click on the Start button.

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

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

    If the Choose an option screen or the Use a device option don't appear, refer to the instructions on starting Tails using the Boot Menu key.

  5. 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:

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

(Troubleshooting Mode)' and 'Tails (External Hard Disk)'.

    • The Troubleshooting Mode entry disables some features of the Linux kernel and might work better on some computers. You can try this option if you think you are experiencing hardware compatibility errors while starting Tails.

    • The External Hard Disk entry makes it possible to start from an external hard disk and some problematic USB sticks.

Starting with the Boot Menu key

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:

Edit the BIOS or UEFI settings (advanced users)

To learn how to edit the BIOS or UEFI settings, search for the user manual of the computer on the support website of the manufacturer.

Take note of the changes that you apply to the BIOS or UEFI settings. That way, you can revert the changes if they prevent the computer from starting on its usual operating system.

In the BIOS or UEFI settings, try to apply the following changes:

  • Make sure that the Boot Menu key is enabled, in your BIOS or UEFI options. This option might be called Boot Device List or something similar, depending on the computer.

  • Edit the Boot Order. 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 start from the USB stick before starting from the internal hard disk.

  • Disable Fast Boot.

  • Enable CSM Boot.

  • Enable Legacy Boot, in addition to UEFI. The computer might not start anymore on its regular operating system if you disable UEFI completely or if you only enable Legacy boot.

  • Try to upgrade the BIOS or UEFI. To do so, refer to the support website of the computer manufacturer.
