To rule out this being a problem with usb-creator, please rewrite the USB
stick directly using dd.  Please note that you must be *very careful* when
using this method: because you are writing to the device directly, if you
get the wrong device name, you can overwrite your system's main disk.

On your existing Ubuntu installation, *before* plugging in your USB stick,
run from the commandline:

 $ ls -l /dev/sdb

this should say:

  ls: cannot access /dev/sdb: No such file or directory

If so, then 'sdb' is the correct device.  If not, repeat for sdc, sdd,
etc.

Plug the USB stick into the computer, and repeat the last command.  If you
have the right device name, it should now show you the device, not an error
message.

Once you have the correct device, run:

 $ sudo dd if=/path/to/ubuntu.iso bs=$((1024*1024)) of =/dev/sdN

where /dev/sdN is the device corresponding to the USB stick.

When that command completes, you will have a USB stick with the unmodified
Ubuntu image.  If that still fails, then there's definitely some problem
with shim (though I don't know what).  If it succeeds, then it's a bug in
usb-creator.

Title:
  Ubuntu doesn't boot from Windows 8 boot menu

Status in “shim” package in Ubuntu:
  Incomplete

Bug description:
  Here are the information and the exact steps I followed:

  - My laptop is ASUS S56CB with Windows 8 pre-installed.
  - Prepared partitions using Windows' own disk management utility.
  - I prepared a Ubuntu 13.04 (64 bit) ISO to boot with a USB.
  - Disabled Fast Boot. When I tried to install Ubuntu in UEFI mode, Secure Boot didn't allow, then I also disabled Secure Boot.
  - Everything went fine and installation started. I continued in the normal way till the partition point.
  - I created an EFI partition, "swap", "root" and "home" partitions and set the bootloader to be installed on the EFI partition. I don't want to use Ubuntu's GRUB loader, so I didn't install GRUB on dev/sda, but on dev/sda5 as the Ubuntu EFI partition was there.
  - Installation finished, and I opened Windows 8. Using EasyBCD, I created a new boot entry and rebooted to see if it would load Ubuntu.
  - When I choose Ubuntu entry, I get this error:

  File :\NST\AutoNeoGrub0.mbr
  Status: 0xc000007b

  If I try starting Ubuntu from UEFI (by pressing Esc while the computer
  boots), I'm able to boot into Ubuntu. However, as I stated it doesn't
  work in Windows 8's boot menu.

  The problem related to Windows 8's boot menu not starting is another
  issue, but the real problem is that Ubuntu cannot be installed in this
  computer without disabling Secure Boot.
