Yes, this sounds like your computer has one of those OEM system recovery
partition configurations that uses a wacky boot flag setup.

I am betting that you now have more partitions than that, but the first
2 partitions should be the ones that the manufacturer used. What I
would try is (hd0,0) first, which would be the first partition on the
hard disk -- I'm guessing that is your bootable Windows partition. The
GRUB boot loader counts disks and partitions starting with 0.

OK, when you see the menu with the choices, here's how to edit. You'll
need to quickly hit a key to interrupt the countdown. Once you can see
the two listings (Fedora and Other), use your arrow keys to move to the
"Other" line. Then hit "e" to edit that line.
Now look for the line that lists "rootnoverify (hd0,1)" -- and hit "e"
to edit that line. Change it to read "rootnoverify (hd0,0)" instead,
and hit "Enter" when done. Then you should be able to hit "b" to boot
the stanza. There is a short help menu at the bottom of the screen if
you get stuck.
Let us know how that works!
