Ubuntu repairing Windows 7 better then Windows itself!!

Situation : trying to install a "strange " OS on my computer i demaged the loader so Win 7 could not start anymore.
Follow the instrucion, it seems easy to repair : use the windows dvd repair function. It SEEMS to work beautifully, it recognize correctly my problem (startup problem), it says the problem is solved but.. it isn't.
now.. what to do? Simple!
Install Ubuntu 9.10 (alfa!!) and magically the boot loader make windows 7 works!!!!
Thanks again Linux!!
