[olug] anyone know how to fix the bootloader on EFI systems?

[Lou Duchez]

Well I screwed up.  I ran grub2-install on an EFI system, and apparently 
one shouldn't do that.  Now my system won't boot without the help of the 
Fedora installation media, and even then I can only get it to the grub 
command line, or (with the right set of gyrations and some good fortune) 
single-user mode and access to the entire LVM file system.

Any suggestions on how to fix the MBR (which is, I believe, where the 
problem lies)?
