Hi,
I've just bought a G75 ASUS laptop with a preinstalled win7 in it. I then tried to installed ubuntu 12.04 64 bits and it crashed at first. Nothing would boot on my computer by then. I then downloaded a new image, finished the installation of ubuntu (and GRUB) and ubuntu booted perfectly. In the grub menu, when I try to boot on windows 7, I have the message "Invalid EFI file path", same when I try to boot on the windows recovery partition.
I have 2 physical HDD in my laptop. Here is the output of "sudo fdisk -l" :

Partition table entries are not in disk order
On /dev/sda (a 256 Gb SSD drive) there is 5 partitions in reality. In order (saw using gparted) :
200 Mb fat 32 partition, where I suppose win7 has it's EFI running (flagged as bios_grub)
unkown partition of 128 Mb, really dark this one, I don't know what it's for (flagged as mfstres)
70 Gb OS partition
143 Gb partition to install big applications
a 25 Gb recovery partition (flagged as hidden,diag)
On /dev/sdb, sdb6 is flagged "boot" and this is where my ubuntu is installed.
I tried boot-repair with several different options (even tried to uninstall grub-efi and install grub-pc ; but boot-repair reversed this), tried to disable UEFI in the BIOS, tried to force boot on sda or sdb, tried all I found in multiple forums ; All without success. I still get the same error message when trying to boot in windows.
I don't have any win7 boot disk, only the recovery partition which I cannot access. I am feeling I don't need to do much to make it work, but I can't understand how to correctly connect the GRUB end to the win7 end...
Can someone help me ? What's with that EFI thing ?
