This affects Precise, Quantal and Raring on ga a75 ud4h hardware. This is not a Secure Boot capable system .
Trying to install using EFI mode when Windows installed using GPT already.
 EFI has to be switched off to allow installer or live session to run. Both default and fallback installers not working when EFI is on. No options from grub list boot - get "can not read cd0/files" and "You need to load the kernel first" errors.

Have asked this http://askubuntu.com/q/208405/102029 question and tried to list some observations at http://ubuntuforums.org/showthread.php?t=2149013.

After installing using the workaround of switching EFI off and then creating grub_bios partition to allow installtion bios mode. Then installing of grub-efi needs other modification to existing boot loader for Ubuntu to boot. This is due to firmware hardcoding by vendors. Boot-Repair fixes things to get going but through time system deteriorates and becomes unrecoverable or bootable due to mountall errors.
