Thanks, seems to work. I was wondering how can I edit a menu entry, is that possible in Bodhi?
WIN+Spacebar opens the QuickLauncher, formerly known as RunEverything. Type unetb and you will see the desktop file with the unetbootin icon appear. It should be selected. Now hit TAB and next choose Edit Application Entry. In the dialog window you can make edits.
Good that you reminded me, the only change to make there is the application line. Insert gksudo in front and the app will start asking for your password and will run if correct. Don't forget to hit apply so the desktop entry gets saved.
If you prefer another method, the desktop file is located in ~/.local/share/applications/
