Restore GRUB with Live CD
For those who use dual Operating Systems (eg. Linux, Windows) you might find this article useful when you come to the time where you need to re-format your Windows Operating System.
In my case, my computer has dual boot with Ubuntu and Windows XP and today I need to format my Windows XP but I don't want lose my entire Ubuntu. Now it's different from in the old day experience, I usually lost every partitions after formatting Windows and I wasn't aware that GRUB can be reinstall to get the boot menu back.
There are serveral ways AND there's an easy way to recover this problem. Just though I'd post it here for my future reference and hoping it might help other as well.
