Lost GRUB while installing windows ? Here is the solution.

GRUB (short for GNU GRand Unified Bootloader) is a boot loader package from the GNU Project. GRUB is the reference implementation of the Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular operating system's partitions.

Here is how:
1. Boot the system from DVD.
2. Choose Repair Installed System
3. System Installation and Update
4. Choose Boot system -> this will give you $ prompt
5. login as root
6. Enter this command: grub-install --recheck <root partition>
7. In most <root partition> is /dev/hda
