trouble booting Ubuntu

[B. Henry]

Please explain a bit more.
Did you install the old ubuntu on to the internal drive, or were you trying to do that when the cable unplugged?
Is there anything on the internal drive at all that you know of? 
You can try typing your user name, pressing enter and then your password at the screen you can not read and see if you log-in to a console. If so, you  
can try running 
sudo update-grub
and see what that does.
I can probably give you a couple more ideas once I know just what you have there, but I'm a bit unclear as to what you have or are likely to have from 
your original post.
I'd make a bootable usb stick with something like vinux5 or ubuntu 16.04 on it if I were you so I could look around and see what is on each disk, and if 
need be do some things from chroot. 
Do you eventually want to be booting from the external drive or your internal drive, or have an OS or two on each?
