I have been trying to install Ubuntu 12.04 alongside Windows 7 on my Asus ux52a Zenbook. I get the following error message:

GRUB Installation failed The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot.

I've been trying to follow the instructions at https://help.ubuntu.com/community/UEFI, but I can't figure out how to disable FastBoot and Intel SRT. I can enter setup during POST, but I don't see these options anywhere. Anyone know where to find them?


The option that's critical to disable is not the "fast boot" feature in the firmware; it's the "fast startup" feature in Windows. This feature turns shutdown operations into suspend-to-disk operations, which means that the filesystems are left in an inconsistent state, which is a recipe for disaster when you dual-boot. See this Windows forum page for details on how to disable this feature.

I know less about the Intel SRT feature, so I can't really comment on it.
