you may be able to stick windows on a USB, google it.
im not sure to be honest ive just always used the copies of windows i have on CD to install.
some links that back up what im thinking:

Using an ISO of the Windows you want to install, extract it into the root directory of the harddrive or USB.
what youre doing is just what you normally do if you burn it to a cd except on a harddrive, and thats making all the install files available from one location.
- For example: if your USB or Harddrive is going by the name G: , then just make sure all the files necessary to install windows appear in that directory. NOT in another folder within the drive, but right out in the open.
Then with the USB or drive plugged into your comp, you start up the computer and go into the boot menu, or bios, or whatever it is your computer uses to change the boot priority, and set it to USB / External Harddrive.
the computer should then read the files as if they are on a cd and go about its business.
