Issue dual booting Ubuntu with a fresh Windows 7 install

I had an existing Ubuntu installation on one drive, and a Windows 7 installation on another. They were both booting fine from grub. I moved the Windows 7 installation to an SSD. I am able to boot to Windows 7 if I select the SSD as the boot device from BIOS. I am able to boot to Ubuntu if that is the boot device.

I'd like them both to work with grub. I've tried various things, using the help of this community for a lot of it. I've gotten to the point where I see: error: invalid EFI file path. From this site I've leaed that I need to add a grub entry that has among other things this line in it: chainloader /EFI/Microsoft/Boot/bootmgfw.efi, where the path and file referenced exist in /boot/efi. On my system, EFI/Ubuntu exists under /boot/efi, but not EFI/Microsoft. I found bootmgfw.efi on the windows partition after mounting it and copied it to that location manually, but when I boot after that I get a DOS-style window telling me that An error occured while attempting to read the boot configuration data and mentioning EFIMicrosoftBootBCD.

I just want to dual-boot these two drives / OSs from grub. What's going on here?
