Case: transfer OS to another hard drive without reinstalling
"I have an old 120GB hard disk drive, and now I want to upgrade hard disk by transferring the 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 hard drive without reinstalling?"
Why transfer OS to another hard drive?
Speaking of why transfer OS to another hard drive, there are two main reasons.
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 disk warning message.
2. The computer runs slowly and you 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 the entire drive to larger hard drive or directly move OS to SSD.
Best OS cloning software to clone OS to another drive
Transferring OS to new hard drive involves complicated conditions and configurations. Many users have reported the disk won't boot after clone, and this isn't the only case you may encounter during the process.
To ensure secure boot, the most important thing is to choose a proper disk cloning tool, which can transfer all boot required drives and files to the target disk.
The reliable OS cloning software - AOMEI Backupper Professional, has been regarded as the best strategy in resolving the problem of "clone OS to another hard drive". It provides two ways for successfully cloning, System Clone and Disk Clone.
System Clone: It lets you transfer OS to new hard drive with the System Clone feature. All system related drives like system reserved partition or UEFI partition will be cloned simultaneously. Further, system customized settings, personal files and installed programs on the system drive will be copied to target new drive as well. In that case, you could get the similar Windows operating environment.
Disk Clone: It also supports transferring operating system from large hard drive to smaller drive, as long as the target space is sufficient for copied stuff. This technology is set by default. If you want to copy every sector of selected system drive, usually the C: drive, to the target, you can specify sector-by-sector clone.
With the help of such a powerful cloning tool, let’s see how to accomplish the OS moving task in detailed steps.
