Need to Clone HDD to SSD in Windows 10/11?

“Recently, I bought a notebook where genuine Windows 10 is already installed but the hard drive is just 1TB HDD and Windows 10 runs really slowly. I want to clone the hard drive to an SSD in Windows 10 and I don’t have the installation disk cos Windows was already installed. Plz can you help me.”

In this scenario, your PC might have a hidden recovery partition which you can use as an installation disk. You will need to copy all of the boot related files from this partition and burn it to a CD/DVD. If you don’t have a disc, you can create a recovery drive in Windows 10/11. Now, you can use the bootable disk to clone Windows 10/11 to a new hard drive.

Why Clone a Hard Drive in Windows 10/11?

Here are some of the common reasons why users want to clone disks in Windows 10/11 laptop or desktop:

  • Upgrading to a larger capacity drive in Windows 10/11.

Usually, manufacturers will ship PC/laptops with low-quality small capacity hard drives, typically around 500GBs. This ends up annoying the purchaser as the drive runs out of space after just a few months. Normally, the user will then consider either getting a new PC (but this can cost a lot of money) or upgrading their hard drive to a large capacity SSD by using reliable disk cloning software.

  • Cloning Windows 10/11 laptop or desktop hard drive for better performance. 

When you receive the low disk space warning error message, you will usually find that your PC/laptop will run slower and slower to the point you can no longer use it. If you’re a gamer, you’ll find that after a few rounds of your favorite online FPS you need an SSD to avoid lag. Because SSDs can make your computer run much faster, accelerate the read and write speed during data transfer, and generally increase overall user satisfaction with the quality of the system.

Before Cloning Drive on Windows 10/11

Before cloning Windows 10/11 hard drive using AOMEI Backupper, there is something you should pay attention to:

  • Backup important data on destination disk to external hard drive before cloning. All of the data on the target hard drive or SSD will be overwritten during the cloning process. 

  • Check the used space on the original Windows 10/11 hard drive. To clone large hard drive to smaller SSD ( like 500GB to 256GB), you have to make sure the used space on Windows 10/11 hard drive is less than or equal to the target SSD. Otherwise, it will fail due to insufficient space. Ignore this information if trying to clone to larger HDD/SSD.

  • Convert dynamic disk to basic disk without losing data at first. If the target disk is a dynamic disk, you will have to convert it first, then you can perform a disk copy in Windows 10/11 as usual.

  • Screwdrivers: to open the back cover on your laptop or desktop.

  • Prepare a 2.5’’ SSD enclosure and SATA to USB cable to connect SSD if you’re running a Windows 10/11 laptop with only one hard drive slot.

Helpful Tips:

  • Edit Partitions: This feature will allow you to resize the partitions on the target hard drive to take advantage of the increased capacity when you clone a smaller Windows 10/11 disk to a larger one. You will get unallocated space on the larger SSD drive if you uncheck "Add unused space to all partitions" (available in paid editions).

Edit Partitions

  • Sector by sector clone: It will clone all of the space, including bad sectors, on the original hard disk regardless of whether it has data stored on it. This function will take significantly longer than the normal cloning process. If the “Sector by sector clone” option is enabled, “Edit partitions” is not available. Resize partition with AOMEI Partition Assistant to show full capacity on larger SSD if needed.

  • Please DO NOT select the Sector by sector clone option when cloning larger HDD to smaller SSD.

  • If you use AOMEI Backupper to clone MBR to GPT disk, you need to change Legacy to UEFI, and vice versa. Cloning system disk between different partition stype is supported by AOMEI Backupper Professional instead of the free version.

  • AOMEI Backupper includes the extremely useful “System Clone” feature which will clone only your Windows 10/11 operating system, installed programs, and drivers to an SSD or HDD. You will need to upgrade to the premium versions, such as Professional, Server, yet the function can save users lots of time and effort when migrating their systems to a new drive – so we think it’s well worth the upgrade.

  • If you want to clone hard drive to SSD on a different computer without installing this software, it's suggested to create portable version of this software with AOMEI Backupper Technician or Technician Plus. Then, open this software on another computer and clone hard drive with "Disk Clone" feature.

What to Do to Make It Bootable after Cloning Hard drive to SSD?

The cloned drive now is bootbale, and just change boot order in BIOS, or replace the old drive with SSD directly to make it bootable.

To change boot priority, restart your PC and press "F2" key (or "Del", "F12") to enter BIOS. At the "Boot" tab, select the SSD drive as the first boot device. Finally, press "F10" to save changes and exit.

To replace hard drive with SSD directly, shut down your PC and remove all external devices and connections. You'll need screwdrivers in the practical operations. It is suggested to take a picture in advance to help you revert cables connections if you're not familiar with such things.
