this is what I used to reinstall grub from livecd after installing windows.

1.boot from livecd

2.open terminal

3.Type the following commands in terminal:

sudo grub (press enter)
find /boot/grub/stage1 (press enter)
//the terminal will show you an output here like '(hdx,y)',note down the values of x and y//
root (hdx,y)
setup(hdx)
quit
reboot (or reboot manually)


hope this helps but wait for some expert opinion.
