I had already given up when the post arrived that was seemingly so simple until
I investigated the files and found them not to have anything in common with the
actual menu entries.
Will drop the issue again.

Now I am trying to figure out how to get the GParted Live installed on my hard
disk and be part of the boot menu so I do not have to go through the hoops of
running Windows just in order to boot an USB stick with GParted Live..

During server idle time this morning I managed to copy *all* the partitions from
my main disk to a USB3 connected drive of the same size, EXCEPT for the Ubuntu
Desktop, which I can boot to and which I used to run GParted.

Would be nice to have GParted Live installed on the boot menu from a separate
partition....
