F-18 Grub borked, how to fix?

Evidently I had some kind of failure during the installation of fedora 18.

Grub2 was evidently not completely installed.

I was able to mostly fix things by doing a grub2-install followed by
a grub2-mkconifg from the rescue DVD.

My system now boots but there is no graphical boot....

I think the problem is that I do not have a 'grub' file in /etc/defaults...

In one of my Fedora VM's it appears that is where some kernel options
are set.

In particular the 'rhgb quiet' seems to be located there,

How can I create a proper /etc/default/grub file ( or download/.install the rascal)?
