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.
