The file 352.jpg does exist, the delay in replying was because I
installed from scratch and setup as you suggested - it makes good sense
to me - I now have some 200 gigs of free space on that drive which is
what I wanted. Thanks for your advice and help.

Now if I was to install MINT, all I have to do is make one new partition
for root and tell it to use the home partition that was setup when I
installed Ubuntu as its home partition at the same time. Also making
sure that the new root partition is formatted. Am I correct in saying
this?
