Creating a bootloader in Madriva?

I have installed Mandriva Linux 2010. I already have Windows Vista. In the bootloader of Mandriva, windows vista is not been shown? how to find it. Can anybody help me please...

if it was an upgade from an previos mandriva install ie 2008 look in the bootloader entery for that it might bring up old bootloader .
redo it with the control center

it is not an upgrade. it is a new installation.

Can you post the output of command

Dear Lakshmipathi,

I managed to create a boot loader. I got both windows and linux. But the problem now is that it is not booting the Linux. It is giving error as "Media Error". I will try to give you more details of the error soon.
