Unable to boot Windows 10 from Bootcamp external HDD

I have installed Windows 10 Pro in Mac OS X El Capitan using Bootcamp, restored the same to external USB 3.0 HDD using WinClone Pro. Now I am getting error when booting to Windows.

Steps followed:

• Disabled SIP in Mac from recovery mode, using the command csrutil disable (this is requested by WinClone)
• Installed Windows in Mac using bootcamp, installed drivers
• Partitioned the external HDD
• Restored the bootcamp installation to external USB 3.0 HDD using WinClone Pro
• Removed the internal bootcamp installation using bootcamp
• Restarted to external bootcamp installation

I am using MacBook Pro (Retina, 15-inch, Mid 2015).

Tried with F8 key, then safemode and it gives like the below:
