When starting Tails, you can specify startup options to alter some of its basic functioning. The two ways of specifying startup options are the following:

Using the Boot Loader Menu

The Boot Loader Menu is the first screen to appear when Tails starts.

The Troubleshooting Mode 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 errors related to hardware compatibility while starting Tails.

  1. To add a boot option, press Tab when the Boot Loader Menu appears. A list of boot options appears at the bottom of the screen.

At the bottom, a list of options ending with 'vsyscall=none quiet_'

  1. Press Space, and type the boot option that you want to add.

  2. If you want to add more than one boot option, type them one after the other, and separate them by a Space.

  3. Then press Enter to start Tails.

Using Tails Greeter

Tails Greeter is the set of dialogs that appear after the Boot Loader Menu, but before the GNOME Desktop appears. This is how the first screen of Tails Greeter looks like:

Welcome to Tails. More
options? Yes, and No toggle button, and Login button.

To start Tails without options, click on the Login button, or just press Enter.

To start Tails in languages other than English, select the one you want from the menu at the bottom of the screen. You can also adapt your country and keyboard layout. When you do that, Tails Greeter itself switches language.

To set more options, click on the Yes button. Then click on the Forward button.

Here is a list of options that you can set using Tails Greeter:
