I than look at another pdf about dual booting bt5 along with mac osx It says i first have to go to bootcamp and install windows 7 os than later override it with linux but I couldn't download windows 7 so now I'm going to try it out on vmware.
That missing "OS" error will get you on a wild goose chase. When I tried that it took a long time to get done, but anyway, if I recall correctly the utility should format the stick for you and then it'll boot correctly, on a Windows PC that is. On a Windows pc the BIOS could give a problem, but I've never used a Mac for anything but OSX. Anyway, also found a link for installing Ubuntu on USB for a Mac
, follow that link and try that method. It says USB install on unetbootin is broken for USB on a Mac, maybe that is the problem? I don't know if this will help you install Backtrack, but trying never hurts. Also, here
I found that link, might also be useful. Good luck!
