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 to transfer the full system including boot files and hidden ones that's necessary to your system.
