May I just mention one thing, here?
I was attempting to do this very same thing around 2 years ago. Installing Zorin (either 8 or 9, I believe it was at that time) to an external Seagate USB hard drive.
From what I recall, Zorin is a wee bit particular about how it's installed. I did manage to get it working, with help from the Zorin Forum; let me see if I can dig up the link to the thread. It may be of some help to you.
Yep; here we go:-
Turned out my problem was because I had the HDD plugged into a PCI-e USB 3.0 adapter card. I've since discovered that no USB adapter has boot capability flashed into the on-card ROM chip...
Nope; that's not relevant to your problem. Yours is to do with how to actually configure the installer.....which, as I recall, is like the Ubuntu Unity installer, since that's what it's based on.
I'm bowing out; I'll leave you in the capable hands of Nick, who's used to doing this. I haven't used the Unity installer for at least two years......Nick, on the other hand, will be using these types of installer fairly regularly.
Apologies for the red herring!
