F-18 Grub borked, how to fix?

view story

http://forums.fedoraforum.org – 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 rasc (HowTos)
