Booting problem with Centos

- Hey guys heres my situation in my box i have 3 OS 2 windows 1 linux (centos) everything works fine not until i changed one of the windows OS. normally when i boot my PC i will have choices either centos or others which is the 2 windows OS. but now after i changed one of the windows OS im directly directed to the 2 windows option. i figured the new windows OS replacement could have mess up the boot loader for centos. is there a way to repair the centos so that i can boot it again...

Just boot up any Linux Live CD and activate Grub in root console.

If Centro is in say hda3 you can tell Grub the root of Cento is in the 3rd partition of the 1st disk by (hd0,2) and set up its Grub in the MBR.
root (hd0,2)
setup (hd0)
You will find Grub back after a reboot.

Remember Grub counts from 0 and (hd0) is the whole disk meaning the destination is the MBR.

If you are not sure which partition Cento resides then issue at the root console command
fdisk -l
It should be the first partition with type No. 83 in your case.
