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

[Anthony Kava]

Did you find a solution to this? I fear EFI thanks to these things.  It seems like the fix would be to boot a live distro and (re)install a boot loader that works with EFI? grub should work with the right options, I believe.

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)?
