If you have a Fedora live disk you can boot to that and use the chroot method to install grub from your Fedora install on your disk. A bit more complicated but good tutorials out there.
Things are always complicated when you do several distros on a single disk. A bit easier if separate disks. You might consider investing in a USB-SSD caddy case and SSD so you can boot external if you only use the function occasionally. Or if you have a DVD drive bay there are SSD drive by converters for that - loose the DVD drive but have a second "hard disk". I did this on my newest laptop to avoid trying to install W8 and Linux on the same drive. It worked out fine.
