[ubuntu] Can't boot into Windows 7 partition after dual boot installation

m trying to set up a dual boot on a UEFI ASUS GV75 laptop. I have 2 drives a SSD with the windows EFI partition and windows OS on it, I also have a SATA drive with data and some programs installed on it.

I removed the SSD from my computer before I installed ubuntu.
I want to install Ubuntu on the SATA partition. I use Windows to shrink the SATA drive. I boot to the ubuntu disk and set up my partitions (a 300 mb partition for Ubuntu EFI, a 25 GB partition for swap space, and a 300gb EXT 4 root partiton).

Ubuntu installs fine, and I am able to boot to ubuntu, so I put the SSD back in my computer. But when I try to boot to Windows the computer just reboots, then boots into Ubuntu. I don't know how the Windows boot manager got messed up since I took out the SSD before installing Ubuntu.

After som eresearch I found this guide: http://ubuntuforums.org/showthread.php?t=2116610 (particulary the 6th post), but after running boot repair, the ubuntu boot loader added the windows boot manager, but when I select it it gives an error saying that the boot manager is missing, and still fails to boot into windows.

So I'm at the point now where I did a restore on my computer and am back to just windows 7, but I would like to get ubuntu and windows working in harmony together. Any suggestions?

Thanks.
