[ubuntu-uk] Partitioning

[David Goldsbrough]

This post is to partly answer my own question at the end of my last post.

These 3 outputs may be useful:-

$ sudo fdisk -l

Note that images will expire 14 days from 12th Feb 2016

I am still left confused as to whether I have a 120GB disk available for
use or 60GB - the outputs and images seem to differ.

As an aside - the cloning process seemed to adversely impact pn my Firefox
settings so I have created a new FF profile and recovered mostly everything
- taught me a lesson to backup FF settings from time to time.

Thanks for all the help.
