How to boot Trisquel 6 in recovery mode (answer)

If anybody is wondering how to boot Trisquel 6 in recovery mode:

1. open a terminal
2. type "sudo su" and hit enter
3. type "nano /etc/default/grub" and hit enter
4. add # to the following line (you can find this line at the bottom of the file)

GRUB_DISABLE_RECOVERY=true

so now it should look like:

#GRUB_DISABLE_RECOVERY=true

exit (press ctrl and x at the same time)

enter the y key when prompted to save

5. type "update-grub" and hit enter
6. reboot

You will now have menu entries to boot in recovery mode.
