Cloning a computer hard drive is one of the most efficient ways to upgrade to a larger or faster drive, back up your data, or migrate your operating system without reinstalling everything from scratch. This guide will walk you through the entire process—from choosing the right cloning software to successfully booting from your new drive. Let’s get started!
Preparing for Hard Drive Cloning
Before you begin cloning your hard drive, it's essential to have the right tools and preparations in place. Follow this checklist to ensure a smooth and successful cloning process.
1. A New Hard Drive (HDD or SSD)
The target drive should have enough capacity to store data from the source drive. If you're upgrading to an SSD, consider a high-performance NVMe or SATA SSD for faster speeds.
2. A Connection Method
If your computer doesn’t have an extra drive bay, you’ll need a SATA-to-USB adapter, external enclosure, or docking station to connect the new drive.
3. Sufficient Power Supply
Ensure your laptop or PC stays powered throughout the cloning process to prevent interruptions.

How to Clone a Computer Hard Drive (Step-by-Step)
Below, we’ll guide you through hard drive cloning with AOMEI Backupper.
Step 1: Connect the New Hard Drive and Backup Files
- For Desktops: Install the new drive inside your PC via an available SATA port and power connection.
- For Laptops: If your laptop has an extra slot, install the new drive. Otherwise, connect the new drive externally using a SATA-to-USB adapter or an external enclosure.
🔔Important: If your new drive is not empty, make sure to backup any important files before proceeding. The cloning process will delete all data on the destination drive.
Step 2: Get AOMEI Backupper Installed
Download the program from AOMEI’s official website. Install it on your PC or laptop after downloading.
Step 3: Launch AOMEI Backupper and Select "Clone"
- Open AOMEI Backupper and select “Clone” from the left tab.
- Choose “Disk Clone” to duplicate the entire hard drive, including the OS, partitions, and data.
Step 4: Select the Source and Destination Drives
- Select your current hard drive (HDD or SSD) as the source disk and click “Next”.
- Select your new drive as the target disk where the cloned data will be copied. Click “Next” to proceed.
Step 5: Configure Cloning Settings
- Edit Partitions: If your new drive is larger than the source drive, use this option to adjust partition sizes.
- SSD Alignment: If you're cloning to an SSD, enable this option to optimize performance and lifespan.
- Sector-by-Sector Clone: If you need an exact 1:1 copy, including deleted and unused space, check this option.
Step 6: Let the Program Finish the Cloning Process
After configuring the settings, click “Start Clone” to begin copying data to the new drive. The cloning process will take time depending on the size of your source drive and the speed of your connection.
Step 7: Boot from the New Drive
After cloning, you’ll need to boot your system from the new drive:
👉For Laptops (Single Drive Slot):
- Power off your laptop.
- Remove the old hard drive and replace it with the new cloned drive.
👉For Desktops (Multiple Drives):
- Restart your PC and enter BIOS/UEFI (press F2, F12, DEL, or ESC during boot).
- Set the new drive as the primary boot drive under Boot Options.
- Save changes and restart.
