I am having the same problem on ICH9 (Intel 82801 RAID Controller). During alternate Installation, grub fails to install and the Installation falls back to the Menu. Screenshot of the VTerminal 4 (debug) is attached. I´ll provide any further information. At the moment I have my PC in a non-bootable state!
