On different hardware  GA A75 UD4H this is a very similar issue
regarding using EFI to install Ubuntu.  Have tried from 11.04 and up to
13.04 all with same result ie does not run installer in EFI mode,
noefi does not work for me but running installer using BIOS/legacy mode
does work then installing grub-efi gets Ubuntu booting using EFI mode.
My bug report
(https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1213119) is still
unfinished and not confirmed as bug as of yet.   There are many similar
bugs to  this one and mine. My own research is indicating this type of
problem is more and more likely to be vendor hard coding of firmware.
This is unproven theory and currently stands as speculation.  Just seems
many vendors creating very similar issues regarding the installation of
Ubuntu using U/EFI and that is with or without Secure Boot.

Title:
  kernel does not boot without noefi on commandline

Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” source package in Quantal:
  Incomplete

Bug description:
  The machine is an ASUS Laptop N53SN.
  In BIOS mode, everything works ok, but in UEFI, the kernel does not boot.

  The only way to boot it is to provide the noefi option on the cmdline.
  This machine never booted with any ubuntu distribution in efi.

  Direct boot with linux-efi kernel image, show the same behaviour.

  The only distribution that boots in UEFI is the alpha version of
  Fedora 18.
