Problem booting on GPT partition.

I have a problem after installation debian on 8TB GPT partition (hardware raid5 - adaptec).
After successful installation my system won't boot, and giving me this error:

Code:

Grub loading
Welcome to GRUB!
error:file not found
grub rescue >

I'm able to boot to my system using Super Grub2 Disk because it detect my boot entries:

Code:

(hd1,gpt2)/boot/vmlinuz-2.6.32-5-amd64
(hd1,gpt2)/boot/vmlinuz-2.6.32-5-amd64 (single)

After logged to Gnome I've reinstalled my Grub:

Code:

grub-install /dev/sda
Installation finished. No error reported.

Unfortunately after reboot I have the same error, could you help me?

Here are my partitions:

Code:

That sounds like you haven't built the grub.cfg (correctly). Don't know how Debian does it, but you'll need to run grub-mkconfig - Ubuntu has a wrapper for this (update-grub), I'm sure Debian would have something similar.

update-grub apllied successfully, but stil the same error in grub

Did you get it to work?

What I did was essentially following:

a) ensure you have efi boot partition with boot flag on (formated as fat16/32)

b) install grub-efi (not grub-pc)

c) run:
install-grub /dev/sda
update-grub

d) ensure that grub.cfg (grub64x.cfg in my case) will be copied to your efi boot partition (into a directory like /EFI/grub)

e) Seemingly ubuntu 11.10 still could not handle the correct installation on efi side, so I had to run efibootmgr by hand.
