Run Startup Disk Creator as Root

Solution 1:

The command for the startup disk creator is usb-creator-gtk. Run it as root with gksudo usb-creator-gtk.

In the future, you may find the apropos command useful. It allows you to find appropriate commands.

In this instance, apropos startup gave me:

default.pa (5)       - PulseAudio Sound Server Startup Script
genisoimagerc (5)    - startup configuration file for genisoimage
start-pulseaudio-kde (1) - PulseAudio Sound Server KDE Startup Script
start-pulseaudio-x11 (1) - PulseAudio Sound Server X11 Startup Script
startup (7)          - event signalling system startup
usb-creator-gtk (8)  - Ubuntu startup disk creation tool for Gtk+

Solution 2:

I do not have access to an Ubuntu machine at the moment and "Startup Disk Creator" seems to be an Ubuntu app. In any case, what you can do is run ps to list running processes before and after running the program:

1. List currently running processes owned by your user and save to a file

   ps xo user,command | cut -d ' ' -f 2- > file1
   

2. Open "Startup Disk Creator" from the menu and then run the above command again, saving the output to another file

   ps xo user,command | cut -d ' ' -f 2- > file2
   

3. Now compare the two files, there should only be one difference, "Startup Disk Creator"

   diff file1 file2
   

4. That's it, you now know the actual command used to launch the program and can launch it as root.
