fedora 17 can't find windows for dual boot

view story

http://forums.fedoraforum.org – i am new to fedora so my apologies because i sure this has been asked before but i couldn't find it in a search. i have my hd partitioned with half the space for fedora and half for windows. i installed fedora second because i thought that grub usually "plays nice" with windows mbr. however when i enter Code: grep ^menuentry /boot/grub2/grub.cfg | cut -d "'" -f2 into the terminal, it only shows fedora. is there a command for it to search for other OS'? or do i have to figure out the address sda, sda1, etc. and then manually edit the config. file somewhere. many thank (HowTos)
