Comment 125 for bug 1325801

I never could get Vivid's usb-creator to create a working live USB, always ending with the error "Failed to install the bootloader", so I filed bug #1446646. You might want to compare logs to see if the errors look the same. I've just been too busy to deal with it any further - for all intents and purposes I've just given up on usb-creator ever working properly.
