I try to save /etc/default/grub after making edits, but I don't have permission and only the owner can change permissions. How do I become the owner?

The best way to edit system files is to open them in a text editor with root permisions.

So:

sudo nano /etc/default/grub

or as Radu Rădeanu suggested:

gksu gedit /etc/default/grub

will work perfectly.

You might want to make a backup copy in case you mess up:

sudo cp /etc/default/grub /etc/default/grub.backup

To restore:

sudo rm /etc/default/grub
sudo mv /etc/default/grub.backup /etc/default/grub

It's not a good idea to change ownership of system files.
