You did this, right? I know it isn't quite the same, but sounds very similar.
My computer starts up to a black screen with white text that states "No Boot Disk Attached." What can I do?
This means that the Windows partition is not bootable, usually because of a mistake in formatting the drive. The Boot Camp Setup Assistant creates the Boot Camp partition, but the Windows installer must format it to make it bootable. Boot into Mac OS X and run the Boot Camp Setup Assistant again. Remove the Boot Camp partition and re-create it. Install Windows again, this time using Windows to format the partition. Refer to the "Boot Camp Installation & Setup Guide" PDF document for more details on installing Boot Camp.
