I am trying to get software for a laptop we got for free but needs software on it. This laptop has no internet acess yet because of this. I have downloaded the file to my current desktop but how do I make a bootable USB if I do not have Ubuntu on my pc? Do I need to make bootable DVD for this application?
You don't need to have Ubuntu on your PC. Download unetbootin, and make a bootable media from the downloaded ISO file. After that you can install it to the laptop.
