Hi again lembas,
I figured it out and I managed to remove the username and password request
from grub.
I opened a terminal and entered the following command to see the username and
password credentials:
sudo cat /etc/grub.d/01_PASSWORD
Then I entered the following command to edit the 01_PASSWORD file.
gksu gedit /etc/grub.d/01_PASSWORD
In order to stop grub from requesting a username and password I commented out
all the lines or you can delete the lines. Then save and type:
sudo update-grub2
Hope this helps other people.
Steve
