I would like to fix the issue by re-editing the GRUB configuration file using Fedora 16 LiveCD.

I proceeded as follow:

mount my system partition [OK]
become super user [OK]
sudo gedit the /etc/default/grub to restore it as it was prior [OK]
(Somehow I had to "sudo" although I already was super-user, that's confusing).
sudo grub2-mkconfig -o /media/MYPARTITION/boot/grub2/grub.cfg

The last step however returned the file system is read only. So I failed to restore the configuration of GRUB2 :(

How should I proceed?

Playing around with the GRUB2 configuration, I did something wrong, which caused the system to fail booting.
