Grub2 booting problems with GPT

[zuku]

Hi,
I've installed debian 6.0.3 od adaptec raid5, but after installation my grub2 won't start giving me error: not found and blinking cursor in rescue mode. Here is print from live cd with my partitions:

sing /dev/sda

As you are using hardware RAID 5, I doubt this is causing the problem, I'd imagine the gpt is at fault - did you use the guided partitioning with squeeze? anyway looks as though your mbr partition is set up okay, so I'd recommend using a live cd such as Super Grub Disk or the debian live cd and chroot into your install just like ubuntu and use

grub-install /dev/sda

and of course update-grub if you're using the debian live cd.

Hope it helps!

Thanks for your reply!
So now I can boot to my new system but only using Super Grub2 Disk which decects my boot entries:

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

So after login I've reinstalled grub:

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

but after restart still the same.
