[Bug 1156076] [NEW] Consistently fails with "Failed to install the EFI bootloader"

[Mike Miller]

Public bug reported:

First off, I am running usb-creator on Debian testing/unstable, I built
the packages from bzr trunk (revision 412). Everything seems to be
working except for the install_efi() method. Unless I modify that method
to return early it always fails with the "Failed to install the EFI
bootloader" error message.

The DVD images I download from cdimage.ubuntu.com contain the path

/EFI/BOOT/BOOTx64.EFI

This is also the path on the mounted USB stick after usb-creator
finishes copying the files from the ISO.

In usbcreator/install.py the existence of this file is checked using a
lowercase path. I gather that this check is failing, so it attempts to
create the file. This then fails because the target filesystem is FAT32.
