Public bug reported:

On a 64bits EFI computer (with GPT disk) with pre-installed 64bits
Windows7. Laptop ASUS N76VZ-V2G-T1002V.

1) Installed Ubuntu 12.04 32bits in dual-boot. Result:
http://paste.ubuntu.com/1069331 (see the 3 efi files on sda1). At
reboot, GRUB menu does not appear, even when setting the EFI BIOS on
/efi/ubuntu/boot.efi  , or /efi/ubuntu/grubia32.efi .

64bits. Result: http://paste.ubuntu.com/1072125 (see the new

allows to boot Ubuntu.
