You may need to go make the dvd again. Before you make the dvd, make sure you have all the devices connected to you system that you will be using when the dvd is make. The 1TB drive, keyboard, mouse or whatever, then make the DVD. Macrium will then be able to go file all the devices, and add the driver to the boot DVD. Maybe you did that already.. but I am adding this info as that is important.. tks.. cliff M.
