////////// RE ADD SWAP PARTITION AS UUID WAS MISSING /////////
1. I added a new drive in Virtual Box.
2. Gparted, created 'Partition Table' then 'New Partition' and formatted as 'linux-swap'.
3. Right Clicked new partition and turned swap on.
4. Checked Swap in use with top command (reported 0).
5. Checked in 'fstab' file and could see old installation entry 'UUID'.
6. Ran 'blkid' to show current UUID of new disk/partion.
7. Used nano to edit the 'fstab' file and update the new 'UUID'. 

swapon --all	// Think turns on swap (same as right clicking drive in gparted)
swapon --summary	// Shows disk in use
