After some futzing around, I have created a flash drive that will load up to a Ubuntu OS. I did this because I want to clone a drive to an external hard drive. I will then be able to place the clone onto another computer. However, I have been unsuccessful in locating a program that performs the clone. Should I be using the "dd" command from a prompt? If so, how do I get to the prompt. Is there another utility that I should have downloaded? Is there a utility available that I can locate with the basic OS? Thanks in advance for your consideration.
