What is System Clone or Migration?
System Clone in AOMEI Backupper is a good feature to clone the entire system partition as well as its all related partitions that are necessary for the system running to the destination location with secure boot.
The System Clone function is particularly useful in the following situations:
Replace the old hard drive with a new one (even for smaller) for better running speed and performance.
Migrate the operating system to another drive, like migrate OS to SSD.
What can you benefit from System Clone in AOMEI Backupper?
As mentioned earlier, System Clone feature will only clone the system partition and all the boot-related partitions, thus you can easily clone system from larger drive to smaller drive or SSD. You just need to make sure the used space on the smaller one is equal to or smaller than the larger disk. And you can enjoy the following benefits during the clone process:
- Clone OS between the same partition style (GPT to GPT or MBR to MBR ) or from MBR to GPT and vice versa.
- Easily extend system partition size with adjacent unallocated space.
- Further accelerate the reading and writing speed of SSD disk as well as its lifespan.
- Clone all sectors of system partition including System Reserved Partition or EFI System Partition, and other system files. It also applies to dynamic system volume.
- Provide two other clone functions, Disk Clone (to clone the entire disk) and Partition Clone.
How to Perform System Clone in Windows 10 with AOMEI Backupper
Firstly, connect the destination drive, SSD, to your current Windows 10 computer. You may need an external disk enclosure or USB-to-SATA cable. This process will clone the entire operating system including system reserved partition and hidden related partitions to the target drive.
Here are the detailed steps to run system clone to SSD:
1. Download this backup software and install it on your computer. Then, click Clone on the left column then select System Clone.
2. The system related partitions are selected by default. Select the connected SSD as the destination location to clone your system drive to.
3. If the selected location is partitioned, a window will pop up to prompt that this partition will be deleted or overwritten, click "OK" to continue. If you don't have a copy of files on the destination disk, please make a file backup first.
4. Then, you will access the Operation Summary window, confirm the disk information and check three other clone features in the following.
Select the "Sector by sector clone" option to copy all sectors of the system partition, which may take more time to complete. Don't tick this feature if the destination disk is smaller, otherwise the cloning process will fail.
The "SSD Alignment" option can also be selected to optimize the performance if the target is an SSD.
The"Make full use of disk space" will be provided if you are moving system to a larger drive, and it is checked by default to make sure no allocated space is left on the target drive after cloning.
5. Click Start Clone to clone system partition to SSD.
After cloning successfully, shut down the computer, remove the source drive from the computer, install the newly cloned drive or SSD then restart the computer. You may need to enter the BIOS/UEFI settings and ensure the newly replaced disk is the first bootable device.
The system partitions do not need to be selected manually as Backupper will select the related system partitions by default.
The destination location cannot be the source disk. Also, make sure the selected drive is large enough to contain the system partitions.
For encrypted system drives, Backupper will use the Sector by Sector Clone method by default.
For systems installed on a dynamic disk, you can use the System Clone feature to clone system drive to a basic disk.
This software also applies to clone all kinds of HDDs and SSDs, such as, clone HDD to Samsung SSD, replace laptop HDD with SSD, clone NVME SSD, etc.
