There are several reasons that you would like to fix your Master Boot Record (MBR). And may be one of those is same as mine, overwritten by Microsoft Windows during re-installation.
- Boot from CD/DVD and get into rescue mode of find a Linux live CD
- Check grub.conf, usually is in /boot/grub or /grub, depends on distribution.

- Write to MBR
First, get into GRUB shell
[user@computer ~]$ grub
Then you have to find which partition is installed with your “grub” directory, if you don’t konw:
grub> find /boot/grub/stage1
