Ok I have a 250gb external USB HD. I hope somebody knows how to partition this thing. The problem I have is I already have files on it. I have about a 100 gb left. I want to partition the empty space and then put windows on that side and then use it to boot from on my laptop. the laptop only has usb 1.1 and I don't know if that will be fast enough. I can upgrade to 2.0 with a card easily. Anybody got any ideas. Thanks.
