I've tried formatting the flash drive as FAT as well as Mac OS journaled through diskutility but still cannot successfully create a bootable drive. I'm following the directions here exactly: http://www.ubuntu.com/download/help/create-a-usb-stick-on-mac-osx
Environment: Macbook Pro trying to create a bootable flash drive for a Macbook Pro. 8GB flash drive. Tested ubuntu-12.04.1 as well as ubuntu 12.20 .iso 64-bit downloads. Nothing to repair in disk utility for this hard drive.
Every time I finish step 8 of the tutorial I get "file system not recognized" with the options to "initialize" meaning to reformat my drive, "ignore" or "eject."
When I try to re-inspect the flash drive in disk utility after plugging it back in I see that it has some error when I try to verify it but the "repair" button is disabled.
I just want to boot to ubuntu when my mac first starts up. Oh the pain. http://lifehacker.com/5934942/how-to-dual-boot-linux-on-your-mac-and-take-back-your-powerhouse-apple-hardware
