And FWIW, this format also indicates that you do not have a '/boot' partition 
or label, instead /boot is a subdir of /

If your 'boot' was a separate partition, then the "/boot" portions of the 
paths used for vmlinuz and initrd would not be there in the grub stanza.

This (hdn,n) in the (hd0,0) means that its the first bios drive, and the first 
partition on that drive.  In other words you have a partition used as /boot, 
possibly even labeled as '/boot' (doesn't care here) and its the first 
partition on that drive.  If your /boot was partition 3 on the 2nd bios 
drive, then this would become "root (hd1,3)"

Your second example would mean that your linux partition (you are dual booting 
perhaps) is the 3rd partition of the drive the bios knows as the first drive 
found and the rest tells me you don't have a separate '/boot' partition 
simply because the full path, not a relative one, is specified.
