I'm not sure if the other answer provided a solution for you. If you 
still have the problem, try this:

IIRC, the Ubuntu live system automatically mounts the available 
partitions somewhere (otherwise mount it manually). Find out where your 
main partition is really mounted. As I don't have the Ubuntu live image, 
I don't know where it is and I'll use /mnt instead of the real path. 
Then use the command

sudo grub-install --boot-directory=/mnt/boot /dev/sda
