i have tried a variety of methods in a attempt to create a "live" USB containing a portable windows, i purchased a Corsair Flash Voyager GS USB 3.0 128GB Flash Drive for this. Unfortunately i have been unsuccessful. If anyone has a good method for this please share it Here is a list of the tutorials i tried: http://lifehacker.com/how-to-run-a-portable-version-of-windows-from-a-usb-dri-1565509124 - This resulted in a bootable USB meaning it was able boot, but it could not initiate the windows 8.1 installation process on a PC or mac http://www.howtogeek.com/196817/how...-go-usb-drive-without-the-enterprise-edition/ - This resulted in a USB containing windows 8.1 but it was unable to find a bootmannager. https://twocanoes.zendesk.com/hc/en-us/articles/203443727-Migrate-Windows-8-to-an-External-Drive- - This migration was supposed to clone the existing bootcamp on to the USB, it took all night. it was able to find the USB and boot, however as it attempted to start windows it halted and tried to repair windows, which it could´t because the USB didn't contain the necessary files.
