Bootable USB for Roadhog?

So I think I have screwed something up trying to make a bootable USB on a road hog? I keep getting this error please see picture...

please help I am having a very hard time updating this console and I need it for a show on wednesday with 3.2 on it...

I had what I thought was the right stuff on the high end bootable USB stick but it said there wasn't enough room to add the road hog system restore release 1.8.2 so I tried to make a bootable disc drive out of a bigger USB stick and then I get the error in the photo? Any ideas? Do I need to do it from a disc drive? Will a apple superdrive work?

thanks
