Is it possible to repair Windows Vista nvidia driver by using Ubuntu 12.04?

http://askubuntu.com – I am currently trying out Ubuntu 12.04 on a bootable USB stick. I have Windows Vista Business Professional as my main OS. I reinstalled the nvidia video driver and ended up with a 'black' screen when booting to Wiindows but the video works fine when booted to the USB with Ubunto 12.04. My computer does boot to Win Vista as I can access the public folders via my home network, I just can not see what I am doing on the lcd screen. I can boot to the USB by feel only. I do not see the DELL splash screen. I do not see the windows logo when booting. Just a black screen. This is a Dell Vostro (HowTos)
