The Boot Loader is the first screen that appears when starting Tails.

You can use the Boot Loader to modify the boot options. Boot options are special parameters that can be useful to troubleshoot or work around hardware support problems. For example, our list of known issues with graphics cards document boot options for different graphics cards.

The Troubleshooting Mode of the Boot Loader 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.

Depending on the computer, the Boot Loader might be either GRUB or SYSLINUX.

Using SYSLINUX

This is what SYSLINUX looks like:

Black screen ('SYSLINUX') with Tails
logo and 2 options: 'Tails' and 'Tails (Troubleshooting Mode)'.

If your Boot Loader looks different, refer to our instructions below on modifying the boot options using GRUB.

To modify the boot options in SYSLINUX:

  1. Press Tab when SYSLINUX appears.

    A list of boot options appears at the bottom of the screen.

    SYSLINUX with
a list of options starting with '/live/vmlinuz' at the bottom

  2. Modify the boot options as needed.

    To add a boot option, press Space and type the boot option that you want to add.

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

  3. Presiona la tecla Enter (de retorno).

Using GRUB

This is what GRUB looks like:

Black screen ('GNU GRUB') with Tails
logo and 2 options: 'Tails' and 'Tails (Troubleshooting Mode)'.

If your Boot Loader looks different, refer to our instructions on modifying the boot options using SYSLINUX above.

To modify the boot options in GRUB:

  1. Presiona e cuando aparece GRUB.

    A new screen appears with more options.

    GRUB with a list of
options starting with 'setparams Tails'

  2. Modify the boot options as needed.

    To add a boot option, navigate with the arrows of the keyboard to the end of the line that starts with linux and type the boot option that you want to add. The line is most likely wrapped and displayed on several lines on the screen but it is a single configuration line.

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

  3. Presiona Ctrl+X, F10, o Fn+F10 para iniciar Tails.
