My apologies, it's just not my day, as you might have noticed by some of
my other replies :D.

AFAIK all Ubuntu and Ubuntu flavor desktop live media by default come
with gparted, so you don't need to burn a new media. If I should be
mistaken, you just need to run

  sudo apt update && sudo apt install gparted

after booting an Ubuntu {,flavour} live media.
