I suppose you didn't copy the command exactly, probably you had a space 
after the "--b". The shell and commands you run from the shell want 
exact spelling including upper/lower case and spaces within words are 
not allowed. So please try again:

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

where you replace the "/mnt" with the real path of your mounted root 
partition.
