[ubuntu] Invalid EFI file path

Hi,

I was trying to make a dual boot with Windows7 and Ubuntu 12.04, i try to find how to make it works since 1 week, i did all things i find or forums, etc...and test many options. Im totally desperate now...

I have 4 hd:

OCZ 120 SSD 120gb
SAMSUNG 840EVO SSD 120gb
WD Caviar HD 300gb
WD Caviar HD 250gb

I want have installed Windows 7 on OCZ and trying to install Ubuntu on Samsung. The other two hds are just for windows files, donwloads, etc....

Im installing ubuntu from a USB UEFI, after many attemps, i make a clean installation of Windows 7 from UEFI CD.

When i enter ubuntu options i select "something else", i create 3 partitions on Samsung:

4gb swap
100mb efi boot
rest ext4

When im in grub2 and i try to start windows 7, i get the error : invalid EFI file path...

I tried many partitions configurations, checked bios options about DHCI or something similar, tried to make a boot repair but program tells me something is mount, even im in "try ubuntu" option.

At boot options i have Samsung as 1st HD and ubuntu loader as 1st option.

I tried refind boot but doesnt recognize the windows, and now i dont know how to unistall it...

I read a lot of documentation, similar errors and no one works for me.

Now, with both systems as EFI, ubuntu dont launch grub2...

There is the boot repair inform:

Can anyone help me or guide me to make this works?

Thanks in advice and sorry if i forgive something, im new here.
