Step-by-step: How to clone your hard drive to another drive

Ready to get started? Here’s a clear, step-by-step guide to help you clone your computer hard drive using AOMEI Backupper—no tech jargon, just simple instructions anyone can follow.

Step 1. Plug in the target drive using a SATA-to-USB adapter, docking station, or install it internally if your computer has space. Make sure it’s properly connected and recognized by your system.

💡 Note: Before proceeding, back up all important data from the new drive using reliable Windows backup software to prevent any loss.

Step 2. Download and install AOMEI Backupper from the official website, then launch the application. Hit “Clone” → Select “Disk Clone” for a complete drive replica.

Step 3. Select your source disk (this is usually your system drive labeled ‘Disk 0’) that you want to clone.

Step 4. Now choose your new hard drive (HDD) or SSD as the destination. Important: This will completely wipe everything on the selected drive!

Step 5. Set up more cloning options:

  • If the destination drive has more capacity than the source, click “Edit Partitions” to allocate unused space.
  • For solid-state drives, enable “SSD Alignment” to prevent slowdowns and help the drive last longer.

Step 6. Click “Start Clone” to initiate the process. AOMEI will replicate all partitions and data to your destination drive.

💡 Note: Completion time depends on source drive capacity, amount of data being transferred, and drive speeds (HDD/SSD).

Step 7. Boot from the cloned drive:

  • Shut down your computer completely.
  • Physically swap the drives (if replacing old drive). For desktops, install the cloned drive in the primary drive bay. For laptops, replace existing drive with the cloned disk.
  • Access your system’s BIOS/UEFI (typically by pressing F2 or DEL at startup) and configure the new disk as the primary boot device.
  • Save changes and exit. Confirm everything is transferred correctly after booting.
