Kali Not able to boot from HDD. [VIDEO]

I installed Kali on my alienware laptop by taking out my internal hard drive and replacing it with another one. Installed it from a dvd and booted it. It worked like a charm. Now I removed that hard drive and put my old on back in its place so I could boot windows from my internal hard drive and have kali on a usb to sata external hard drive, it doesn't work. I can get to the grub, but after that I run into some issues and Kali won't boot. Here's a video hopefully someone will be able to point me in the right direction. I am new to this community and look forward to meeting everyone! All help is greatly appreciated! *removed*
Alright so since my video got removed here's the error I'm getting. unable to enumerate USB device on port... anyone know a fix for this?
