Make the computer start on the USB stick

This step is the most complicated one as it depends a lot on the model of the computer:

  • On most computers, our basic instructions to get to the boot menu work fine.
  • On some computers, you might have to do more advanced techniques, like editing the BIOS settings.
  • On a few computers, it might currently be impossible to start Tails. But, it is very hard to know without trying.

The goal is to reach the Boot Loader Menu of Tails:

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 a boot menu:

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

    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:

    AcerEsc, F12, F9
    AsusEsc, F8
    FujitsuF12, Esc
    HPEsc, F9
    LenovoF12, Novo, F8, F10
    SamsungEsc, F12, F2
    SonyF11, Esc, F10
    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.

    If the boot menu key that works on your computer is a different one than the first in the list, please let us know. You can write to (private email).

This animation explains how to use the boot menu key:

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

Edit the BIOS settings

If none of the possible boot menu keys from the previous technique work, or if the USB stick does not appear in the boot menu, you might need to edit your BIOS settings.

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. That way, you can revert the changes if they prevent the computer from starting 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 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.

If none of these options work, we are sorry but you might not be able to use Tails on this computer. Feel free to report the problem to our help desk.

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