While I was installing Ubuntu I unplugged my Windows 7 HDD so I wouldn't accidentally partition it. I installed Ubuntu, shut off my computer, plugged back the HDD, rebooted (and using the BIOS boot menu, selected Ubuntu). Ubuntu recognized the HDD with Windows 7 on it, and can mount it fine. However, I cannot get it added to the boot-loader.
I have tried boot-repair with several different settings, and it detects Windows 7, but it doesn't add it to the boot-loader.
