Need to know chipset.

Hi guys

I am having real difficulties in getting Windows back on my machine after having Ubuntu on it.  

When I am trying to install it says it can't find the drivers so I went onto youtube and found out how to download the drivers from Intel RST.  Now I have the problem of finding out what my chipset is without having an operating system on my laptop...How do I find it from the Bios only?

It is really driving me nuts!  Been trying to reinstall Windows for about 2 weeks now... I do have a backup laptop but is nowhere near as good as the one I have.

Thanks in advance
