How do I move Windows 10 to a new hard drive?

The hard drive on our American Legion Post computer is getting shaky and I'm wanting to get a new drive and install back into the same computer - same motherboard etc. The Windows 10 OS is the upgrade to an existing installation of Windows 7, so I do not have a disk. Is there a way to put this Windows 10 OS on a new drive or do I have to purchase Windows 10?

- Question from

Just like this user, you may want to upgrade hard drive in Windows 10 because the current drive is failing. Upgrading hard drive is also needed in following situations:

◈ The current drive has small capacity, so you want to upgrade to a larger hard drive to gain more storage space.
◈ The computer is running slowly, and you want to replace hard drive with SSD to improve the working speed.

The most important part of hard drive replacement is OS transfer. Some users choose to reinstall Windows after replacing the old hard drive. However, the reinstallation process is really time-consuming and all your data and applications will be erased. You have to reinstall those applications and recover files after reinstalling Windows 10. How frustrating it is!

Is there an easier way of replacing hard drive in Windows 10? Disk clone is the answer.

How to upgrade hard drive to SSD in Windows 10 step by step

▶ Preparations:

1. Connect the target SSD to your computer and make sure it is detected.

▪ If there is an SSD drive bay inside your computer, you can install your SSD there.
▪ If there is no SSD drive bay available, you can connect it externally through a SATA-to-USB adapter.

2. Backup files on the destination SSD, because the drive will be overwritten during the cloning process.

▶ Detailed steps of upgrading hard drive to SSD with AOMEI Backupper:

Step 1. Run AOMEI Backupper. Click “Clone” on the left pane and select “Disk Clone”.

Step 3. Select the destination SSD you have connected to your PC and click “Next”.

Step 4. Tick “SSD Alignment” to improve the reading and writing speed of the target SSD. Confirm the operation and click “Start Clone”.

>> Sector by sector clone: it will clone every sector on the source disk no matter it is used or not, thus costing more time. It requires the destination disk to be equal to or larger than the source disk.


1. Boot from the cloned SSD.

  • If you have installed the target SSD in the SSD drive bay, you can change boot order in BIOS to boot from it.

  • If you have connected the target SSD externally, you can now remove the old hard drive and put the new drive there. A mounting bracket may be needed to fit the size of the HDD drive bay.

  • If the source and destination disks are in different partition types (one MBR, one GPT), you should then change boot mode in BIOS to boot from the cloned drive.

2. If the cloned SSD works perfectly, you can wipe data on the old hard drive to release storage space.

About Windows 10 license after upgrading hard drive

You may care about whether Windows 10 license can be transferred to the new hard drive. There are four different situations for your reference:

1. If you upgraded from a retail version of Windows 7, 8, or 8.1, you can transfer your license only once.

2. If you have a full retail copy of Windows 10, you can transfer as many times as you want.

3. If you upgraded from an OEM Windows 7, 8, or 8.1 license or used OEM Windows 10 license, then the license cannot be transferred.

4. If you upgraded using the Easy Upgrade to Windows 10 Pro Pack from Windows 10, you can transfer the license using Digital Licensing.
