What is System Clone and Why Clone Windows 8?

System clone refers to creating an exact copy of the operating system, which is different from a system image that requires restoration before using. When you implement system clone in Windows 8 or other OS, you usually need a target disk to receive the data, and it should be bootable after cloning.

Generally speaking, Windows 8/8.1 system clone could be performed for following purposes:

  • Migrate Windows 8 to SSD for better performance.

  • Move Windows 8 to HDD with larger capacity.

  • Clone system to external hard drive as a backup...

To illustrate further, here’s a practical case:

"Bought a Samsung laptop that has Windows 8 on it. looking to throw a 256GB SSD in place of the 750 HDD. How can I copy over the Win 8 to the SSD and boot from it?"

As you know, SSD is considered as better boot drive than HDD for its higher speed and lower power needs. Many people nowadays would like to clone operating system to an SSD for better performance. Therefore, I’ll take this case as an example to introduce how to clone Windows 8/8.1 to SSD.

How to Do System Clone Easily and Safely?

Before looking for any other method, you may want to try Window built-in utilities. But here’s the case: Windows Backup and Restore only supports creating a system image, which could be restored to a new hard drive, but with a probability of failure. Besides, image and clone are two completely different concepts.

As for File Explorer copy & paste - yes you could manually copy most of personal files, but not system related files. If you want to move Windows 8 to new HDD or SSD and boot from it successfully, this is not an effective way.

In this case, a system cloning software supporting Windows 8/8.1 as well as other OS would be the most labor-saving choice. It could simplify the process as much as possible. The steps are roughly like:

Install system cloning software > Connect the new hard drive (HDD/SSD) to your computer > Perform Windows 8 system clone > Restart and boot from the new hard drive

AOMEI Backupper is a good choice of assistant software because it supports disk/system cloning in all Windows OS with simple operation and high success rate.

☛ In the free Standard edition: There’s Disk Clone feature to clone a system disk to another disk without reinstalling. If it’s an SSD, you could tick SSD Alignment to accelerate its reading & writing speed. And the intelligent cloning mode even allows you to clone larger HDD to smaller SSD.

☛ If you upgrade to Professional edition: You’ll enjoy more powerful features, like using System Clone to migrate only OS to another hard drive, cloning Windows 8 in dynamic disk, or between MBR and GPT system disks without additional conversion.

◆ Connect the target hard drive: 

If your PC has only one drive bay, use an USB to SATA adapter to connect it. Otherwise just install it directly.

◆ Backup the hard drive: 

All the data on the target disk will be overwritten after cloning. If you’ve got some important data on it, please backup the hard drive first.
