This didn't work for me. First, there were 6 folders, not 5, for the IndianSummer release. Perhaps the [BOOT] folder should not be copied? Second, when I opt to use the UEFI boot option for the USB drive, the following error continuously scrolls on my screen:
error: no such device: /boot/grub/x86_64-efi/2014-11-23-04-45-08-00
