generally, when this happens - I look at the grub config that specifies
the logical drive numbers. For example, 
title Red Hat Enterprise Linux AS (2.4.21-15.0.4.EL)
        root (hd0,1)
        kernel /vmlinuz-2.4.21-15.0.4.EL ro root=LABEL=/ 
        initrd /initrd-2.4.21-15.0.4.EL.img


where (hd0,x) looks good, it may be that the drive is actually hd1

so at the grub prompt, choose 'e' to edit and change the drive parameter
and see if it does indeed boot. These boot time changes can be made
permanently later when you figure out what works. Also, bios and logic
don't always work. You can install grub in /dev/sda but the bios may
have it boot off a IDE drive (i.e. /dev/hda) and in that case you need
to grub-install /dev/hda
