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 . 2) Removed the Ubuntu32bits partitions, and replaced it by Ubuntu 64bits. Result: http://paste.ubuntu.com/1072125 (see the new /efi/ubuntu/grubx64.efi file). At reboot, the GRUB menu appears and allows to boot Ubuntu.
