How to make a bootable usb from a notebook

Sounds like monkeymike1 wants to have windows installed on a usb drive that will boot on multiple machines. That's not as simple as it might seem because it would need drivers for both machines. Unless both laptops are the same or similar model, there could be problems caused by this since drivers don't like to coexist.

One possible solution would be to have linux on the USB drive and run windows in a virtual machine. If you did that you would want a distro of linux that has a low overhead, something like Xubuntu, Lubuntu, Tinycore, etc. That should solve any driver issue so long as the Linux distro has drivers and some distros are much better about drivers than Windows.
