The windows came with the laptop and i have a genuine key but no disk, is there a way to make a copy of it onto disk?

I have been having trouble with my laptop. A couple of days ago i had the BOOTMGR missing problem but now i have managed to get windows to load up. The problem is now that when windows is running it is very slow and the hard drive light is constantly on. Im no genius @ comps and have no idea what i can do to fix it?

EDIT: I fixed the bootmgr prob by using a windows repair disc as i did not recieve the install disc with the computer.

I have installed Windows 7 on my notebook but it says ‘general VGA graphics adaptor’ in device manager when i know i have an NVIDIA GeForce Go 6400 series graphics card however i can’t seem to get the computer to find this card.
I’ve checked NVIDIAS website and they dont have any drivers for this card nor do any other drivers work for it.
Could someone help please!

I am getting a new laptop for christmas with windows 7 and i wondered if all my peripherals will work?
