Thanks Tim. You make it sound so simple.

I searched for "chroot to mounted disk to update initramfs" and found 
several detailed descriptions of the process.

Thank you so much.  I will give it a shot today and report back.

Thank you again Tim. It worked.

I found an excellent overall guide in the debian wiki that could be 
applied to fix any number of issues with a dead system:

Here are the exact steps I took, just in case it can help anyone else 
with problems similar to ours.
