Using gnome-disk-utility happens only on a stick which was formerly not used with dd and applications based on dd. In this case you must create a new partition table and a new partition with gparted. Any messages concerning sector size must be ignored.
With nautilus (Ubuntu 15.10) you open open the contect menu of the iso-File and select 'Write disc images' or so (I use a German Ubuntu) .
