Lost Grub boot loader | How to reinstall?

[garg_anoop]

Hi All,
I had a dual boot system to boot Vista and Suse 10.3. Its was working fine but today I had to do system recovery for Vista due to some annoying thing in windows. The recovery [I hate it now] probably deleted Grub boot loader from MBR. So as a result my system does not have a dual boot anymore. It always boots Windows Vista now. This is what I have tried so far to resolve this issue:
Boot system from Suse 10.3 DVD and
1. Try Repair Installed system. Result:It gives an error and finally Prompts with a menu where I can select Installation and system update and other things, which also did not help.
2. Rescue System. Result: Does not help, same as above.

I have almost everything in my suse partition and most importantly I don't want to loose my 10.3.
I was thinking if I could reinstall Grub and things could start working again. If that's the right path then how can i reinstall it?
Please help.

Resolved!!
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

Thanks everyone!!
