You are trying to boot Windows from an external drive connected by USB?
I think it can be done, but only with considerable difficulty and jumping through a bunch of hoops.
Assuming that you want to INSTALL Windows on an removable external drive, it is possible. :)
You can use PWBoot (Portable Windows Boot Project). Just Google it.
That's because it was never meant to do that. Moving it to different hardware causes driver issues. You'll have activation issues too. Windows To Go is the official way to do it. You need Windows 8.1 Enterprise for that though. There are unofficial tutorials on how to create your own Windows To Go drive. Just google it. May or may not work though, as its not sanctioned by Microsoft. Even if you do get it to work you'll likely still run into activation issues if you move it from PC to PC.
USB throttles the OS speed terribly. Not really worth the trouble unless you're using eSata.
But MS cares about the activation, which is why they make it as impossible as they can to install to an external drive unless you use Windows To Go which they designed for that purpose.
How did you make the external bootable exactly? You realize it must boot via USB which will make it horribly slow? An OS is meant to run internally and not via USB.
