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.

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.
