How to Replace Laptop Hard Drive and Reinstall Windows
This part will describe how to install Windows after replacing hard drive. There are several steps to achieve that. Therefore, you should follow the instructions below carefully just in case something goes wrong in the process. Let's come to the details.
Part 1. Backup Data First
Before replacing the laptop's hard drive, one of the most critical things to do is to back up your files, including documents, photos, music, videos, program installation files, and more.
Part 2. Create an Installation USB Drive or Disc
You should create an installation disc or USB flash drive to let your laptop run from it and reinstall Windows.
Visit the Windows website to obtain the ISO file depending on different versions. After replacing your hard drive, you can use the Windows Media Creation tool or a professional tool to create a bootable USB from ISO to reinstall Windows 10. Ensure the disk space on your USB device is adequate.
Part 3. Remove the Old Disk and Install the New Drive
It is time to remove the old drive and replace it with a new one after completing the necessary preparations. Before starting, make sure your laptop is off and disconnected. Then, carry out the following steps:
- Remove the screws to open the laptop case.
- Find the hard drive and remove the disk's power cables and data wires.
- Pull the old hard drive out after removing the screws.
- Simply reverse the steps to install the new drive. Insert the disk in its original place, attach the data and power connections, secure the new hard drive with screws, and close the case.
- The operations vary depending on the manufacturer. You can look up the user manual or in-depth instructions for a specific brand online.
Part 4. Reinstall Operating System
After replacing the old drive, you should reinstall the OS on the new drive first. The steps below show how to install Windows after replacing a hard drive. Take Windows 10 as an example:
Step 1. Insert Windows 10 installation disk into your laptop and boot from it. For that, you can press a specific key to enter the BIOS menu and then change the boot order to run the computer from the installation media.
Step 2. Select your Language, Time, and Keyboard, and click Next.
Step 3. Click Install now.
Step 4. The Windows Setup program will ask you to enter Windows 10 product key. Click on I don't have a product key, and Windows will be activated later on by itself.
Step 5. The Setup program will also prompt you to choose the edition you have a license for. Please be careful to select the correct edition. Then, accept the license terms and click on Next.
Step 6. Click Custom: Install Windows only (advanced) to proceed with the installation.
Step 7. Choose the unallocated drive, click New, Apply, and then Next.
- Instead of seeing an unallocated disk, if numerous partitions are shown, you can pick each one (beginning at the bottom) and click Delete to convert them to unallocated space.
Step 8. You will have new partitions. Choose the primary partition and click Next.
Step 9. The Setup tool will start to install the operating system. This could take a while.
After the installation, you'll go to the Out of Box Experience page, where you can customize specific Windows settings, such as setting up a user account, establishing privacy preferences, installing applications, etc.

Better Choice: Replace Laptop Hard Drive Without Reinstalling Windows
As mentioned, you must reinstall the required apps and the Windows operating system to use the laptop normally. This is troublesome because it is time-consuming. So, is there a way to replace a laptop's hard drive with SSD without reinstalling Windows and its programs?
The answer is in the affirmative. You can clone your old hard drive to a new one to avoid reinstalling Windows and applications. Cloning allows you to move all the data from the old hard drive to the new one, including Windows files, system settings, programs, documents, etc.
To clone your old hard disk to a new one, you must use professional cloning software because Windows does not have a built-in tool with a cloning feature. In that case, EaseUS Disk Copy, a professional disk cloning tool, comes to help.
EaseUS Disk Copy is a multi-functional cloning program for Windows 11/10/8/7. It allows you to clone your system, disk, and partition. And it enables you to clone a hard drive with bad sectors thanks to its sector-by-sector clone technology. In addition, it lets you migrate the operating system from HDD to SSD and SSD to SSD and transfer the C drive to a new SSD without reinstalling Windows and applications.
You can perform the following steps to clone your old hard disk to a new one.
- The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
- All data on the destination disk will be completely erased, so take care.
Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".
Step 2. Choose the other disk as the destination disk.
A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".
Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the source" or "Edit disk layout".
- "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
- "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
- "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.
Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.
Step 4. Click "Proceed" to officially execute the task.
