Re: [2.00] grub-install use on UEFI system?

Probably because your kernel doesn't handle EFI properly so grub-install
wasn't able to detect it (/sys/firmware/efi was missing).

Hi Vladimir

- here is an example where /sys/firmware/efi is not missing: http://paste.ubuntu.com/1227221

Because this is not part of efi-directory

Yes, exactly. This is why i don't understand Chris comment.
 

(and RTFM)

AFAIK there is nothing about this subject (grub-install for UEFI) in GRUB 2.00 Manual:
http://www.gnu.org/software/grub/manual/html_node/Invoking-grub_002dinstall.html#Invoking-grub_002dinstall

Thanks in advance for any input. (GRUB with UEFI problems are more and more frequent on forums.)
