I have this problem as well. The only thing to do is backup your stuff, fdisk and delete your Windows partition. That way when the Windows installer loads up it'll find unformatted space to install itself on. This has got to be the dumbest thing ever, though, that an OS with security updates can't recognize the same OS without the security updates.
