Grub2 doesn't find it's config file after clean Kubuntu installation

[JR]

I've installed the latest Saucy Kubuntu image (amd64) on a new machine last friday. This is my first time with a efi system - and I don't have any experience with that. It seems the Kubuntu installer correctly added the Kubuntu boot entry to the efi boot manager.

My system has 2 Harddisks, a SSD and a normal one.
I boot from the SSD.
I've chosen manual partitions:
  * the efi partition
  * a boot partition with ext2
  * the root partition with btrfs

after rebooting, i get into the grub-shell.

after that, I need to type

configfile (hd2,gpt2)/grub/grub.cfg

and grub starts as normal. I'd prefer having grub finding it's config file by itself. I even don't know how to force this config file manually.

I forgot to mention: in the grub-shell, when i enter 'set' I see a prefix that uses hd0,whatever, but I think it should be hd2

I've no idea, why it is hd2 in grub, because I think I only have hd0 and hd1 (linux also shows /dev/sda and /dev/sdb), so I'm not sure if the actual bug is grub using hd2 instead of hd0 or using a wrong path.

Interesting to say: in my last reboot, i had to use hd4 instead of hd2, but there was no hardware change.

Same for me: Kubuntu 13.10 (stable, amd64), hdd+ssd, boot partition (+system) on ssd.
After a (complete!) fresh installation the notebook boots into the grub console instead of booting the system.
To boot kubuntu I have to type

   configfile (hd0,gpt1)/EFI/kubuntu/grub.cfg

Everything else runs fine ootb, just grub is not finding this config file on its own.

Found the solution:
Entering "set" in the grub console shows the prefix points to "EFI/ubuntu" instead of "EFI/kubuntu". Boot the system, copy the folder "/boot/efi/EFI/kubuntu/" to "/boot/efi/EFI/ubuntu/" and everything works fine.

This is definitly an error in the default installation configuration - should be fixed as fast as possible!
I have no idea where the grub configuration is placed.

Status changed to 'Confirmed' because the bug affects multiple users.

I just tried a fresh download of kubuntu on my UEFI system and ran into this bug. Solution provided here worked.
