I agree with that. It happens all the time. The partition with the Windows boot loader files is very commonly the next partition. Anaconda (the Fedora installer) is a sucker to fall for utility partitions as the Windows partitions. Study the results of these, and you may be able to figure out how to edit the "Other" section of the grub.conf file and correct it...
Then open grub.conf for editing with this...
If you don't see what to do or try something that doesn't work, then post those things here. Someone will probably see something for you to try.
