Can I repair the bootloader for Fedora 17 from Ubuntu 12?

Question

I don't have access to the install media for Fedora right now. Can I restore boot loader for Fedora from Ubuntu 12?

Why do you think you need to restore the boot loader? What error are you getting?
I could not boot into fedora. (Fatal error occurred... blah blah blah.. ! and Kernel Panic"

You can try this:

Boot your Ubuntu.
Open a terminal and mount the Fedora partition: sudo mount /dev/sdXY /mnt/fedora (where sdXY is the partition where you have Fedora installed). Most likely, X will be a (for the first hard drive installed in your system).
Just for good measure, mount /dev and /proc there: sudo mount -o bind /dev /mnt/fedora/dev and sudo mount -o bind /proc /mnt/fedora/proc. I don't know if this is still needed but it won't hurt.
chroot into it: sudo chroot /mnt/fedora. This will give you access to your Fedora install.
Then, run /sbin/grub-install /dev/sdX.

I have solved this issue. What I did is :

First I have copied the grub.cfg from my Ubuntu installation and replace that with Fedoras grub.cfg.
After that I have changed some entries in grub.cfg, like I have replaced the UUID, Name of the initrd file and msdos9 to msdos3.
After that rebooted and got access to Fedora.
After that used Grub Customzer to re-write grub entries for fedora.
