Installed Windows alongside Fedora 21 now GRUB isn't functional

I had separate partitions for Root(/)(30GB) and home(450 GB) for my fedora install! I wiped my home partition and re partitioned it to 100GB for a new install for windows and the rest for my home partition. After I installed windows and rebooted my laptop it didn't go into grub rather it directly booted into windows. the 30GB partitioned hasn't been wiped. I read on a forum that such windows install over-writes the windows bootloader over the GRUB and hence booting into Linux is directly possible! Kindly help as to how I can reinstall GRUB and continue using the wonderful Operating System that Fedora21 is! Thanks

Take a look a this answer -> https://ask.fedoraproject.org/en/question/60906/problem-reinstalling-grub2-fedora-21/

In short: Boot with a live CD: From a terminal : $su

grub2-mkconfig -o /boot/grub2/grub.cfg

grub2-install /dev/sda

Replace /dev/sda with the device of the drive you boot.
