I currently am using a Crucial 64GB SSD for my OS as my boot drive. It is running out of space, so I am getting a Kingston 120GB SSD. To make sure that the transition to the latter goes off without a hitch (and so that I don't have to reinstall anything), how do I go about cloning or imaging my current drive to create a bootable disk using the new one? I'm sort of new to system building, so step by step instructions would be nice. Thanks in advance.
