Dual Booting LL 2.0 with other Ubuntu (14.04) based distros

EDIT:  I just thought of something that I forgot to ask you before.  Did you have any Virtual Machines created in VirtualBox before you bound the "VirtualBox_VMs" folder to the DATA partition?  If you did, you won't be able to see those anymore.  They will still exist, but you won't be able to access them with the bind in effect.  I can give you instructions on how to find them and transfer them to the DATA partition if you run into that problem.  Let me know if you need to do that.

I did have a couple of virtual machines before but I saved them both to  my external drive in their VirtualBox folder, before doing a clean install of the OSes, followed by binding to DATA partition.  By doing that I seem to have saved myself some extra work, judging from your above comment. 

Yes, I'm really pleased I've got this far with linux, being a complete newbie in April (from Win XP) and without any prior programming experience. I am getting into it, though have to admit I don't always understand what I'm doing, though with time everything will become clearer (as it already is), bit-by-bit. Many thanks for all your careful advice gold_finger, though suspect I'll be in touch again sometime...

Mike
