“I have an old 120GB hard disk drive, and now I want to upgrade hard disk by transferring operating system to another hard drive without reinstalling everything because I am tired of the low disk space problem. It makes storing new data and installing new applications impossible. The most unbearable point is that the computer works at a very low speed. So is it possible to transfer OS to another or new hard drive without reinstalling?”
– Microsoft Community
Of course, the answer is Yes, you can definitely migrate OS to new drive without reinstalling Windows and application you will use in the near future. But Windows won't make this process simple, so you need to turn to third-party software for help. The simplest way is to clone entire OS to a new hard drive or SSD to gain big capacity or better performance.
Many users have reported the disk won't boot after clone, and this isn't the only case you may encounter during the process. Thus, to transfer OS to new hard drive while ensuring secure boot, you need professional OS migration software. Here I strongly recommend you AOMEI Backupper Professional. For details, please keep reading to learn more.
Before transferring OS to another hard drive with AOMEI Backupper, you still need to get the reasons why do this, so that you know exactly what you are doing. There are two main reasons in the following.
1. The system partition or entire disk is out of space. This is a very common reason for all computer users. In general, the disk comes along with your computer is very smaller. In addition, you may install many new programs and add a larger number of new files to your computer. At last, you will get a low disk warning message.
2. The computer runs slowly and you want to get better performance. After using a computer for a period of time, you may find that your computer does not run smoothly as before. Then, you may want to transfer operating system to new hard drive or directly move OS to SSD.

It provides two ways for successfully cloning OS, System Clone and Disk Clone. You can choose the way as per your needs.
✦ System Clone It lets you transfer only OS to new drive, for example, clone OS from GPT to GPT, or between GPT and MBR disk. All system-related drives like system reserved partition or UEFI partition will be cloned simultaneously. Furthermore, system customized settings, personal files and installed programs on the system drive will be copied to the target drive as well. Thus, you could get a similar Windows operating environment. ✦ Disk Clone It allows you to move OS to new drive by cloning entire disk. It uses "intelligent clone" feature by default to help you clone large hard drive to smaller drive, as long as the target space is sufficient for copied stuff. If you want to copy every sector of the selected system drive (usually C: drive) to the target, you can specify a sector-by-sector clone.
With the help of such a powerful cloning tool, you can accomplish the OS moving task effortlessly.
