 From your grub output it looks like your root partition is sda6 and you 
don't have a separate boot partition.  Thus you could:

sudo mount /dev/sda6 /media

At this point you could do an 'ls /media' to make sure that it contains 
the linux directory tree.  If all is well, do:

sudo grub-install --root-directory=/media /dev/sda6


p.s. I noticed on another thread that you had recently installed a 
second dvd drive.  I wonder if this could have confused grub and caused 
it to fail.
