I installed 12.10 on a totally blank computer with a new media and had the same problem.
It has a CF slot, hence I'm installing 12.10 on the CF card from a USB key.
At first reboot after installation, i get the same problem, namely
This is the case no matter if the usb key is inserted or not.
I tried
>ls
(hd0) (hd0,msdos1)
>set prefix=(hd0,msdos1)/boot/grub
>insmod (hd0,msdos1)/boot/grub/linux.mod
error: attempt to read or write outside of disk 'hd0'.

Using snippets from http:// karuppuswamy. com/wordpress/ 2011/09/ 09/how- to-fix- grub-rescue- prompt- without- live-cd- for-grub2/ I am trying to at least boot once and get into a proper shell, and not just "grub rescue", but that's in vain.
I tried (hd0,msdos1) /boot/grub /boot/grub/ linux.mod
>ls
(hd0) (hd0,msdos1)
>set prefix=
>insmod (hd0,msdos1)
error: attempt to read or write outside of disk 'hd0'.
*sigh*
I've always hated grub2.
