The seventh attempt failed: I tried again with usb-creator-gtk, the version in the 'proposed' repository. See also comments #117-118 of the bug report https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1325801 The version of usb-creator-gtk from 'proposed' fails to install the bootloader. The version that comes with 14.04.2 LTS could install the bootloader but is affected by bug #1325801.
