Confirmed on a fresh installation of Ubuntu 14.10 on Lenovo Y480.
Error Code is:
/EndEntire
file path: /ACPI(xxxx)/PCI(2,if)/Sata(1,0,0)/HD(2,xxxxx)/File(\EFI\Microsoft\Boot)/File(bootmgfw.efi)/EndEntire
Problem is persistent after apt-get update && apt-get upgrade && update-grub2 && grub-install /dev/sda.
Disable SecureBoot is a valid walkaround.
Consider shim works pretty well on Fedora 20 and OpenSUSE 13.2, I suggest this is a Ubuntu-specific bug.
