Upfrading from Ubuntu 14.03 to Ubuntu 16.0

The reason for the question is that upgrading to ubuntu 16 has crashed 
the machine. I cannot get to the files since I cannot log on.  I have 
backups which contain the full home directory including the virtual 
machines.  I need to be able to restore the machine to ubuntu 14.04 and 
then decide whether I try the upgrade again.  I have two laptops 
involved. One of them comes up in a terminal and I can see all of my 
home directories.  This machine has not been backed up for a month.  
There is not much work need to repeat the months work but it would be 
nice to be able back these files up before I proceed any further. Is 
this possible form a terminal session?

If I use a DVD which enables me to try ubuntu before installing will 
this let me get at the files and back them up?

What is meant by a live DVD?

Sorry to be generating so much traffic but at over 80 I find it hard to 
grasp some of the concepts.
