Yes but the first time I looked at it a couple days ago I could not
figure out how to change it.  Turns out it is a GUI (3 icons near lower left
of main display, each represents a disk, highlighting them display desc,
draging them changes order, a slider allows seeing 4th disk etc.  My
"intuition" for such GUI's is pretty poor, I grew up used MSDOS, command
line etc for too long. )

I still wonder what "Ubuntu" that boots what looks like the Ubuntu 1310
Live disk version.  There must be a way to find the UUID of the
drive that / resides on.  Looking in /etc/fstab for this installed
version tells me.

Now that I've got it booting ok I should be satisfied but here are a few
more curious details in cse anyone is interested.  FRed


After changing the boot sequence, the bios boot menu still listed "Ubuntu"
at the top but does not boot the Ubuntu Live look-alike. (Selecting the
DVD drive does boot the Live DVD in that drive.  Putting "Ubuntu" back at
the top of the boot sequence did not boot Live look-alike either.  Now
it seems to boot into the installed Ubuntu 14.04 even with "Ubuntu" back
at the top.  It does however during boot up display error / warning message
(briefly) that includes "No caching page found"

Searching I found at
http://ubuntuforums.org/showthread.php?t=2224353

 [SOLVED] Won't boot after clean install of 14.04

 OK, I started digging around online to find an answer to this one, and
 found that the error message (no caching page found...or something
 like that) appears only when some form of external storage is plugged
 in when booting up. And then I just happened to remember that I have
 an external hard drive I had connected to the system all the time. So
 I tried unplugging it...and VOILA, my system now boots up!
