can't write Grub in MBR

[wildnux]

I am trying to install grub in MBR. I have working configuration on my root partion. I tried "grub-install" on MBR but gives me some warning.

/usr/sbin/grub-install /dev/sda
WARNING! You are trying to invoke the unsupported grub-install script
with a parameter. To really do this, call grub-install.unsupported.
You should rather call "yast2 bootloader" or create configuration files
appropriate for the intended target.

Also I tried it from Yast but still MBR has Chamelon boot loader.
(I have chamelon boot loader, I want to overwrite my MBR with current grub configuration on my root partition.)

I tried using grub-install.unsupported but it did not work either. it says:
/dev/sda does not have any corresponding BIOS drive.

I tried grub-editor (kde module) to do the work, but it gives me error:
grub-install returned and unknown error exit code 1.

What am I doing wrong?

That worked like charm. I just typed grub (root) and then followed the instruction.
