When using the computer for a while, most of us have a plan to upgrade the old hard drive to a bigger one and it seems unavoidable. Then the issue comes. How to transfer OS on the older drive to a new one? Because the existing operating system runs great and we don't want to reinstall it. However, simply copying the operating system to your new disk doesn't work. What your need is a disk cloning or imaging, which can help transfer the full system including boot files and hidden ones that's necessary to your system.
Cloning can transfer all contents as the same as original, while imaging transfers your system as a image file. To clone or image your hard drive, you need a drive cloning or imaging tool. Wondershare LiveBoot Boot CD can help do both. You can choose either of them to transfer your OS.
