Trouble with createinstallmedia when making bootable USB to install Mavericks

I am have been trying to make a bootable USB to install Mavericks on a external partition (so I can continue to use iDVD 😝)


I have downloaded Maverick install app from App Store and I followed Apple's instructions from here Create a bootable installer for OS X - Apple Support


The Install OS x Mavericks drive appears when I hold down Option when booting, but then just hangs at a screen a circle with a line through its center (the international symbol for "No!")


I am using OS X El Capitan on a Mac Mini (late 2012)


Could anyone advise on what I am doing wrong?

I meant, what folders and such do you see on the thumb drive, but that is probably a moot issue. That command above creates a install media thumb drive, which will install Maverick onto your Mac system, when you boot from it.. I am thinking that you want to create a thumb drive that you can boot and work off of, not install Maverick. I do have bootable non-installer thumb drives for the last three versions. Right off I am not able to find my directions for how I did this, but it looks like Eric Root (above) has a link to a utility that will create a stand-alone bootable thumb drive, which i suspect is what you want. I can go look in my other work location for the instructions if you prefer, but you might try Eric's solution first.
