How does your system currently boot? If it goes through a GRUB menu to
boot either windows or Linux, then it is. If so, you don't need to
change it.
Run your install for Fedora 10, and tell it to install the GRUB
bootloader into the new Fedora 10 boot partition. That'll leave the
existing bootloader alone.
Now, after that's run its course, add an entry to your older Fedora 7
grub.conf file to chainload the new partition. After you've done this
the boot sequence will be thus: The system will boot up the same as it
used to, with a GRUB menu for windows or your Fedora 7 installation,
plus an option for your new Fedora 10. If you pick Fedora 10, it'll
chainload over to Fedora 10's bootloader, and 10's GRUB menu, and you'll
have a choice about which kernel to boot Fedora 10 with.

Going by the above information, the chainloader details for Fedora 10
would be:
title Fedora 10
rootnoverify (hd0,2)
chainloader +1
You'd have a similar entry for your Windows boot, but something other
than ",2" inside the rootnoverify command.
