Pretty simple straight-forward question yet I cannot find an answer on the net. All I want to do, is use Universal USB Installer, or YUMI or any other image-to-usb loading program to put a distro of Ubuntu Server (an .iso direct from Ubuntu.com) on my USB, boot from it, and install the thing on another drive WITHOUT USING THE INTERNET. It seems that no matter what I do the installation from a USB always attempts to start downloading the package contents, and there's no option to load the contents from the USB (similar to how you load the contents from a CD/DVD when you install it that way). Seriously, what is the difference between burning the .iso to a disc and loading the .iso to a USB? I've downloaded the image specifically so that I don't have to download anything else and install Ubuntu as many times as I want without the internet.
Am I going about this process completely wrong? It's driving me insane
This program will do the trick for most Linux distributions.
