better, restart the computer again on your Tails USB stick.

     1. Navigate with the arrows of the keyboard to the end of the line that
        starts with <span class="code">linux</span>. The line is most likely
        wrapped and displayed on several lines on the screen but it is a
        single configuration line.

     1. Press the <span class="keycap">Backspace</span> key several times to
        remove the <span class="code">quiet</span> option from the command line.

     1. Type <span class="code">debug nosplash</span> to add these options to the command line.

     1. If Tails previously failed to start and displayed the
        following error:

        <p class="pre">Probing EDD (edd=off to disable)...</span>

        Then type `edd=off` to add this option to the command line.

     1. Press **Ctrl+X**, **F10**, or **Fn+F10** to start Tails.
