Something about the SSD you’re about to move to

SSD is short for Solid-State Drive and it refers to a data storage device, which can be used to store data persistently by integrated circus assemblies. According to different interfaces and form factors, SSDs can be divided into 2.5", mSATA, M.2, and PCI-Express.


Which type of SSD you need to choose depends on the available ports on your motherboard. Compared to HDD (Hard Disk Drive), it possesses better performance in reading and writing speeds as well as system security. SSDs are known for fast running speed for games and software that occupies lots of CPU. However, it is usually more expensive than HDD when it comes to the same capacity.

Many well-known SSD manufactures are available on the market, such as Samsung, Western Digital (WD), Corsair, Crucial, Intel, Toshiba, Kingston, etc. Each brand has its own distinctive features and you can choose the most suitable one for your condition by referring to this page: Best SSD in 2019.

Why need to transfer OS to SSD?

Windows OS (Operating System) refers to the environment and command structure within which we can run programs, play games, watch movies, etc. and installed on C drive in most cases. However, moving OS to SSD usually does not mean moving only C drive to SSD especially when there are many other boot-related partitions such as EFI partition and System Reserved partition.

Some users prefer the arrangement of SSD for OS and HDD for storage to fully take advantage of each sort of hard drive. To be specific:

  • To save time and effort. For most of the users, it has been regarded as a hard problem to do the migration, because it would cost a lot of time to reinstall the operating system, updates, drivers, and some other necessary applications.

  • To increase space for operating system. The low disk space error would prompt when there is insufficient space for running programs. OS migration from small partition to bigger SSD is not a bad choice.

  • To upgrade computer’s build. In general, the most prevalent reason of copying OS to SSD is to take full use of SSD and gain better performance.

Once you search on Google, you can find the best solution is to clone OS to SSD with some powerful and reliable migrating tools, which can be regarded as a time saver.

Migrate OS to SSD in Windows 10/8/7 via the best OS migration software

The comprehensive yet easy-to-use migration software - AOMEI Backupper will be highly recommended. It can help move OS to SSD in Windows while keeping the operating system, applications and settings exactly the same as they should be. It's possible to transfer OS to SSD that's smaller than the original drive.

Besides, it supports MBR/GPT partition styles, BIOS/UEFI boot modes, 2.5"/mSATA/M.2/PCI-E SSDs and works in all Windows PC operating system such as Windows 10, 8.1/8, 7, XP and Vista.

With AOMEI Backupper, there are two ways to transfer OS to SSD with different editions. You can choose the one which is most suitable for you. By the way, no matter which way you choose, the following preparations are alike.

Before you do:

  • Uninstall software you aren't using anymore, delete unnecessary files and transfer data that you don't want stored on your SSD. (optional)

  • Check and make sure your SSD has more space than the total amount of operating system, applications and data in C drive you're migrating.

  • Install your SSD alongside existing hard drives in the same computer and make sure it can be detected. For a laptop, if there is no extra room to install SSD, you need a SATA-to-USB adapter to connect SSD, and then plug into a USB port on your laptop. Your laptop should detect your new SSD as an external hard drive.

Way 1: Migrate OS to SSD via Backup-and-Restore on Laptops [Free Version]

This way is to use "System Backup" and "System Restore" to indirectly implement OS migration to SSD. It is more complicated and will cost much more time than Way 2. In the first place, download, install and launch AOMEI Backupper Standard.

Download Freeware

Step 1. Click "Backup" -> "System Backup" to create a full system image.

System Backup

Step 2. After system backup image has been created, click "Restore" and then click Select Task or Select Image File.

System Restore

Step 3. In the backup point page, choose a backup version, and then click "Next".

Select Backup Image

Step 4. Check the box before "Restore system to other location" so that you can migrate OS to SSD. And then, select a backup point to restore and click "Next".

Restore System To Other Location

Step 5. Select the SSD (here is Disk1) which you want to migrate OS to and click "Next".

Select Destination

Step 6. On the operation summary window, you can check the box before "Align partition to optimize for SSD". At last, click "Start Restore".

Preview Restore To Other Location

Nowadays most laptops have extra rooms for installing more than one disk. But if there is only one single room for disks in your laptop and you don't have a SATA-to-USB adapter to connect SSD with laptop, you can create an image of HDD and save it to an USB or network share folder -> create a bootable media -> swap HDD with SSD -> start up laptop with bootable media -> follow the above Step 2 to restore the disk image.

However, we suggest you buy a SATA-to-USB adapter which also can be used to connect your HDD to laptop as secondary drive after restoration is completed.

Way 2: Much Easier Way to Clone OS to SSD Directly [Advanced]

Detailed steps to clone Windows 10 to SSD:

Step 1. Install, launch and register AOMEI Backupper Professional with license code. Then select "Clone" -> "System Clone".

Choose System Clone

Step 2. The source drives (OS drive and boot related drives) is selected by default, and you only need to select the SSD as destination location. If the SSD is not empty, the program will prompt you all partitions on SSD will be deleted. Click "Next" to continue.

Choose Destination Partition

Tips: If you transfer OS to another hard drive, select the HDD here instead of SSD.

Step 3. Preview the operation. At the lower left corner, you can choose whether or not tick the checkbox before "Sector by sector clone". Tick the checkbox before "Align partition to optimize for SSD". Finally, click "Start Clone".

System Clone Preview Sector Checked

The time of OS migration process depends on how much data you have. After complete, click "Finish" to exit. And then, restart your computer and enter BIOS to set boot order. You can still use the old hard drive as a secondary drive for backup SSD and data storage. With this system clone software, the operation of migrating operating system to SSD can be completed through just a few clicks.

Tips: No matter which way you use, the original OS won't be removed automatically after restoration or clone. You can manually delete it or reformat the hard drive after your computer successfully boot from SSD.


You may need to migrate OS to SSD in Windows 10/8/7 out of different reasons, and to ensure cloned drive boot up successfully, two methods of OS migration are introduced.

The backup-and-restore method is recommended for laptop users because it avoids potential problems like cable disconnected, power supply, and so on.

The OS cloning method is more straightforward and convenient for desktop users. Besides, the Professional edition supports cloning hard drive from command prompt, which offers a solution for unattended cloning tasks. Overall, pick one of them based on your own situation.
