Windows 7 RC via Boot Camp - no optical drive

So I've been trying to install Windows 7 RC for the past few hours or so on my late 2009 unibody Macbook. The install went fine, but when Windows loads up, I open My Computer and there is no optical drive present. I've tried reinstalling it several times, and reburning the image, but there is still no optical drive present. My girlfriend also has the same model MacBook, and it does not detect the optical drive after the install either. I have no clue what to do, does anyone have a solution? Thanks

Cliffs:
-Install Win7 with Boot Camp
-Installs fine
-Does not show optical drive in My Computer to install Mac Drivers
