Hi,
I met a very similar problem (but my Windows version was old Millennium Edition and I had two IDE drives). I found out that it depended on the GRUB boot loader settings. The Fedora installer did create entries for dual booting Fedora and Windows, but the boot menu was hidden. To solve that, I edited the GRUB configuration file (you need to be root for that), that is, /boot/grub/grub.conf: I commented out the "hiddenmenu" line (to comment, add a # at the start of the line). Further, i had to add four more lines:
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1
as described in the GRUB manual, or else Windows did not start.
Hope this helps!
