I just went in to edit /boot/grub/grub.cfg and the first thing I seen in the file was this:
# DO NOT EDIT THIS FILE
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
How am I to make changes if the first thing I see is a comment telling me not to make changes or edit this file.

Grub2 is a bit complex. At the end of the linked page there are some links that explain how to edit the config files.
