[SOLVED] recovering Windows MBR through ubuntu live cd

[vickey_20]

Recently I brought my friends laptop at home and installed Linux on external HDD. By mistake I have installed boot loader on the internal HDD of the laptop with all the grub information on the external HDD. So windows on the laptop doesn't boot unless I attach the external HDD to the laptop and choose windows from the grub. Now the problem is that I have to return this guy he's laptop back , He's totally non technical and would be shocked to see the Grub error
I googled some pages and found this link How to fix your Windows MBR with an Ubuntu liveCD|ArsGeek
But when I do as it say's I get this error

vickey@vickey-laptop:~$ sudo apt-get install ms-sys
[sudo] password for vickey: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Couldn't find package ms-sys
vickey@vickey-laptop:~$

SO the problem is how do I reinstall the MBR through linux as I don't have the windows recovery disk with me.

You can use SuperGRUB CD/Floppy/USB to re-install Windows Boot Loader.

I only want to put Windows on my friends laptop i.e recover the orignal MBR which I have messed up. Can that be done with it

Man I m stuck !!
I selected the option of windows from super grub and then fix mbr but it just shows some dd line and hangs there.

Could you post exact error message here?

Do you have Windows Installation CD of any version? Windows 98 or XP?

bingo the ms-sys package is available on the this website
Debian -- Package Download Selection -- ms-sys_2.1.0-1_i386.deb
I downloaded the packege on the ubuntu live cd and gave this command
sudo ms-sys -m /dev/sda and it worked like charm now wi(n)dow boots properly.
Thanks for the help anyway.
