Does your Fedora core install boot and/or run properly? You have what looks like some errors or your written your post wrong. You say your swap is /dev/hda7, but you've got /dev/hda7 setup up as Linux, not swap. Your hexcode should be 82, not 83.

Code:

/dev/hda7 7837 7849 104391 83 Linux

should say..

Code:

/dev/hda7 7837 7849 104391 82 Swap

As far as your chainloading problems, check out this thread I found on another forum. They have some good advice.

Or if your lazy, here is a working grub.conf snippet from a guy with a similar problem,

Code:

title WinXP64
rootnoverify (hd2,0)
makeactive
map (hd2) (hd0)
map (hd0) (hd2)

Windows is strange because it always wants to be the first drive. You need to remap the drives so Windows can boot up. The lines below should boot up Windows.

title Windows Xp

map (hd1) (hd0)
