Why Windows To Go cannot boot my computer?

Computers certified for Windows 7, Windows 8 and Windows 10 are required to have support for USB boot. Check to see if any of the following items apply to your situation:
  1. Ensure that your computer has the latest BIOS installed and the BIOS is configured to boot from a USB device.
  2. Ensure that the Windows To Go drive is connected directly to a USB port on the computer. Many computers don’t support booting from a device connected to a USB 3.0 PCI add-on card or external USB hubs.
  3. If the computer is not booting from a USB 3.0 port, try to boot from a USB 2.0 port.
  4. Some computer's BIOS have problems with booting USB drives larger than 32/128GiB. That means on these computer, the system partition and boot partition can't span beyond the 32/128GiB boundary.
  5. There is not enough power on the USB port for the USB drive to work, please connect the USB storage device to an external power supply.
If none of these items enable the computer to boot from USB, please contact the hardware manufacturer for additional support.
