Deleting older dual boot version

Question

I did a fresh install of 16.04 along side 14.04 last summer. I am satisfied with 16.04 and want to remove 14.04 from GRUB and free up the disk space that 14.04 is occupying. What steps should I use?

Is there a separate /boot partition, or is /boot only directory below /? Please post the output of sudo fdisk -l /dev/sda and dfto assist — ridgy, Dec 09 '16 at 15:49
I think editing the question in case there is more than one disk could also be helpful so please include lsblk as well. — ianorlin, Dec 09 '16 at 19:23
