It seems that you accidentally installed windows 7 onto your Recovery partition. While not ideal this can be remedied. You could attempt to install Windows again, but this time, delete all partitions and create a new one with the unallocated space and install again. It should be possible to delete the old partition and extend the one you currently have Windows 7 installed to, although I remember that this is usually difficult to do. If you do not wish to reinstall Windows again, I will be asking gregrocker, our resident expert on such matters, to take a look at this thread just in case.
