hey ,
these are the lines which you should refer and change your the grub.conf file
># NOTICE: You have a /boot partition. This means that
># all kernel and initrd paths are relative to /boot/, eg.
># root (hd0,5)
**** change your to some thing like this
># kernel /vmlinuz-version ro root=/dev/hda7
># initrd /initrd-version.img
