I have the same problem with an Acer V5-531. After installing ubuntu 12.04.2 I had to manually install "shim-signed grub-efi-amd64-signed linux-signed-image-generic" and do "sudo grub-install /dev/sda --uefi-secure-boot". I'm able to boot ubuntu either with or without secure boot enabled, but Windows 8 boots only with secure boot disabled, otherways I have this error:
