Re: Would Like to be a Ubuntu Convert
As I understand it, you want a traditional install, not simply a Live USB with persistence. Provided your external drive is not solid state, that's probably the better approach.
Unetbootin will not directly create a traditional install. It creates Live media (USB/CD/DVD).
In order to do a traditional install, you need to create a Live USB/CD/DVD that is separate from the external HDD where you want the traditional install. Then, boot from the Live media, attach the external HDD, run the installer, and select the external HDD as the destination drive.
Jane, stop this crazy thing!
