Configuration files are usually owned by root. For example:
$ ll /etc/default/grub
-rw-r--r-- 1 root root 6801 Jul 18 13:26 /etc/default/grub

In order for a user (yourself) to edit /etc/grub/default you need to use sudo powers. So instead of using:
gedit /etc/default/grub
You must use:
sudo -H gedit /etc/default/grub
At which point you will be prompted for your password.
