What you can do is, choose what default OS you want first.
Then pick up its Live DVD, boot and run live, on terminal, use
sudo os-prober to find out the list of OSes,
get the number /dev/sdaX from your list that indicate your default OS choice,
follow by two commands
sudo mount /dev/sdaX /mnt , replace X with your actual number
sudo grub-install --root-directory=/mnt /dev/sda
