google chrome usb stick download ?

[XoxxOx]

google chrome and google have both been uninstalled from my other laptop and now i cant access the internet at all, though the internet does work, i can still sign into msn. I have tried to restore my computer to a point where google was still installed on my laptop but there is a disk OC: error that i cannot seem to fix. I need some help. I want to somehow get google chrome onto my usb stick (im not to sure howto do this as i dont want to copy shortcuts, obviously they are usless) and onto my laptop. Can i even do this? How? Or if you can help me out in any other way or with my other problems please give me a answer/s.
Thanks.
