Windows installed and running but can't boot to it from reboot + option key

Not entirely sure what's going on. Installation was horrible--especially when it reboots? It kept going to a blinking question mark folder. I eventually got around that by holding option on start-up and selecting the Windows CD.


So everything installed fine--I'm typing this from Windows right now and installed all the Apple BootCamp drivers.

However, I'm UNABLE to boot into Windows 7 Ultimate from a reboot holding option key and selecting "Windows". I just get a blinking question mark folder.

The only way to get into Windows is to pop in the Windows CD and select that at start-up when holding option.

I also tried booting into Windows from OSX in Startup Manager--but no dice.

I understand the question mark folder means it can't find the OS.

Any way to fix this without having to install everything all over again? Windows is running perfect, but having to boot it from the CD sucks.
