Why Need System Clone in Windows 10?

System clone, also known as system migration, is the process of creating a bootable and intact copy of Windows 10 to another disk. It is quite common among today's computer users, mainly applicable to these scenarios:

  • Low disk space: With time goes by, the free space of a hard disk will become less and less due to the installed apps, temporary files, caches, etc. Sooner or later, you will be warned with low disk space.
  • Poor performance: Computer hardware is updated quickly, an old hard drive that is still functioning can hardly keep up with the demands of new apps and games. Therefore, you may want to replace the system drive with a new SSD to improve the performance.

In these cases, many users choose to upgrade hard drive in Windows 10/11 to a larger drive or an new SSD. And if you don't want to follow the conventional way (install Windows 11 from scratch and migrate the important data over), system clone is the best way to go.

It eliminates the need to reinstall Windows 10 and allows you to quickly use the familiar system on the new disk. All the data you need can also be cloned over together.

How to boot into Windows 10/11 from the cloned drive

When the cloning is complete, you can shut the PC down to replace the old hard drive with the new one, and then boot from it. Note that if your PC has more than one slot, you can also keep the old hard drive connected and do the following:

1. Restart the computer, press the required key (could be DEL, F2, F12, etc.) to enter BIOS. The specific key depends on the manufacturer and model, which you can directly search in Google.

2. Set the new hard drive as the first boot option, then press F10 to save the change and exit.

BIOS Boot Order

If your computer boot from the new drive successfully, it means the system clone is successful. Then, you are free to decide what to do with the old hard drive. You can either discard it or keep it as a secondary storage device. AOMEI Backupper also integrates a disk wipe feature to help you clean a hard drive completely.

Windows 10/11 System Clone FAQs

Can I clone just the operating system to SSD?

A: Yes, you can clone just the operating system to SSD. One way is to create a system image first and then restore it to the target SSD; Another way is to pick a cloning software with the System Clone option and perform the OS migration directly.

Does cloning a drive make it bootable?

A: Cloning a hard drive means creating the exact copy of the original drive, including the system, applications, and settings. If the source drive you cloned includes all the required system files, then the target drive should also be bootable after cloning.

What's the difference between disk clone and system clone?

A: Disk cloning refers to the process of creating an exact replica or copy of an entire hard disk drive (HDD) or solid-state drive (SSD). This includes all the partitions, files, folders, and the operating system (OS) installed on the disk.

System cloning, on the other hand, refers to the process of creating a copy of the entire operating system and the system configuration, including installed applications, settings, and preferences. It focuses on replicating the software environment rather than duplicating the entire disk.

Can I clone a Windows 10 disk onto a larger disk?

A: Yes, you can clone Windows 10 to a larger disk, or a smaller disk as long as it has enough capacity to hold all the existing data. The key to perform system cloning between disks of different sizes is using an adequate migration tool, such as AOMEI Backupper.

Can I clone my Windows 10 system to a different computer?

A: Yes, it is possible to clone a Windows 10 system to a different computer, but it may require additional steps to ensure compatibility. You may need to install appropriate drivers for the new hardware after the cloning process is complete.

In fact, it's suggested to use the System Backup and Dissimilar Hardware Restore feature to do that more securely.

Do I need to activate Windows after cloning my Windows 10 system?

A: If your Windows 10 license is tied to your hardware (OEM), you may need to reactivate Windows after cloning to a new computer or significantly changing the hardware configuration. If it's a Retail license, then there should be no problem. Ensure you have a valid license key or contact Microsoft support for assistance.
