It's a long story, but there's a new MBA 4Gb on my desktop, a Superdrive plugged into it, and a Parallels install partly finished. And I'm not a Mac Guru, just asked to play one on television... Win7 64bit is loaded in the drive on CD. It's a good disk, having installed in on the older MBP with not enough memory to run the apps it needed in Win mode. The Superdrive shows as running on SATA 0:2, iirc, and that's somewhat questionable this morning. Win7 fails to boot there, or on any other setting for the Superdrive. The image shows on the Mac desktop, though, so the brand new, ripped from the cellophane this morning drive seems to be working. It's plugged into the USB port on the left... So I'm suspecting a setting in the Parallels install, but banging my head on where to find it now? Help, please, from someone who knows these woods!
