I do not believe that what you are attempting to do will likely prove successful. Installing Windows on a removable USB drive is certainly not a prescribed method and I suspect would require additional supporting third party software like PWBoot and or USBWatch, to make it work.
Even if you manage to jump through all the hoops to get it working I suspect you wouldn't be too happy with the performance issues you would likely encounter.
I wish you the best of luck but suspect that you'll likely need to attach the or a drive more conventionally in order to get your install to work properly.
