Not booting after Winclone 7

I have followed Winclone 7 and when I try to boot up the windows partition on my external SSD I get what looks like a prompt screen with cursor then a quick flash of a blue screen the reboots into mac operating system. Why did the Winclone not transfer any drivers or the exact same as what my Bootcamp uses for windows 7 pro. I have no issues booting into with internal HD.

External booting can be problematic. Did you see this?


Thanks for the reply, I’m trying to clone Windows 7 Pro to an external SSD to replace my HD in a mid 2012 13” MacBook Pro. The used GB are pretty much the same amount so I’m not sure why it doesn’t boot up.
