Thanks! Forgot about bootinfoscript. That actually does the job as I can
see that the grub2 in use is sda5 (karmic) and my sda7 (lucid) is not
from the 'Boot sector info:':

====
sda5:
_________________________________________________________________________

    File system:       ext4
    Boot sector type:  Grub 2
    Boot sector info:  Grub 2 is installed in the boot sector of sda5 and
                       looks at sector 205505817 of the same hard drive for
                       core.img, but core.img can not be found at this
                       location.
    Operating System:  Ubuntu 9.10
    Boot files/dirs:   /boot/grub/grub.cfg /etc/fstab /boot/grub/core.img

sda7:

    File system:       ext4
    Boot sector type:  -
    Boot sector info:
    Operating System:  Ubuntu 10.04 LTS

Thanks!
