Do I have to run grub-install as well?  If I do, what is install_device?  I

Yes, you do. Run:

grub-install /dev/sda

Hi Tony,

Not sure if you've already found it, but there are some useful step by
step commands here:https://help.ubuntu.com/community/Grub2. I found
them useful in a similar situation.
