As a possibility - you don't say how many partitions you have.
I *think* Grub just counts 'actual' partitions. Easiest shown
by an example:
Linux name Grub name
/hda1 Windows (hd0,0)
/hda2 Windows (hd0,1)
/hda3 Extended --
/hda5 Linux (hd0,2)
/hda6 Linux (hd0,3)
/hda7 Linux (hd0,4)
So your Grub command root (hd0,4) will show an
ext2 partition but it's looking at /hda7 not /hda5,
hence can't 'see' your vmlinuz on /hda5.
In the above example you'd need root (hd0,2)
