I tried to install Ubuntu Quantal AM64 on a EFI - GPT notebook (asus X501U) in dualboot. Ubuntu works fine, but i can't boot windows anymore. HDD is partitioned in this way: sda1 0.2 Gb boot efi sda2 0.128 Gb sda3 60 Gb Windows sda4 210 Gb Data sda5 15 Gb Ubuntu sda6 4 Gb swap sda7 25 Gb recovery image Booting pc, grub2 runs, but if i try to select "windows 7 loader on sda3" i receive this message: "error: invalid EFI file path." If i select "windows recovery Environment on sda7" i receive: "error: impossible find command "drivemap" - error: invalid EFI file path."

I installed dualboot ubuntu many times, but this is the first time on a EFI - GPT system.
