I confirm that upgrade process (from 14.04 to 16.04) crashed on my laptop LENOVO G410 like Pilot6 said.
I also booted with livecd 16.04, then chrooted to the system. In my case I did also execute
fsck /dev/sda1
That was because my first partition ended up with a lot of INODE problems.
Finally I was able to reboot Ubuntu 16.04 with GUI.
There is more...
I ran dpkg --configure -a
When I tried to do this
apt-get install -f
at the first time I was not able to execute, because there was broken packages. Ubuntu offer the option to open with SYNAPTIC, so I did with Synaptic.
At the end finally
apt-get install -f
again
_____________________________
No part of this problem but at the end of the day I notice 16.04 is tooooo slow to boot.
I did
systemd-analyze blame
I see a lot of packages with execution time bigger than 15 seconds
I double check any swap problem it seems to be everything OK.

Ubuntu 16.04 is working, fortunately I didn't lost any personal file, but it was hard and long to rescue.
