Before you start, it is very important to have a parameter backup of your machine. This will help restore your machine in the event that it loses memory or if you need to perform a hard reset. The white USB that comes with your new machine contains the parameter file, so please make sure to save that file. If for some reason you don't have the file, please follow the instructions in this video to create a parameter file of your machine.
