DVD drive is connected to the secondary SATA controller during install. Windows reports CD/DVD device driver is missing and needs to be located. The issue is Windows 7 DVD has no drivers for the controller the DVD drive is connected to so Windows install cannot proceed without them.
Load the drivers for the controller the DVD is connected to onto a USB key in point the installer to the drivers and proceed as normal.
Change the controller the DVD drive is connected to and/or load drivers for the other controller if the drive is still not detected.
