Replacing a laptop's HDD to an SSD or a larger hard drive involves three key steps: First, complete the HDD cloning. Then, replace the hard drive. Finally, modify the UEFI/BIOS boot order to boot from the new disk. This article provides a step-by-step guide to the entire process.

 

How to clone an HDD to an SSD or larger HDD?

To quickly clone your laptop HDD to a new drive, you need reliable and efficient software. For this purpose, we recommend Hasleo Disk Clone. It provides core cloning features including partition, disk, and system cloning free of charge, making it a top choice for hard drive upgrades and data migration.

Before you begin, please ensure that: Your target SSD's capacity is larger than the used space on your source HDD; the SSD is compatible with your laptop's interface. We strongly recommend cleaning up junk and temporary files from your old HDD beforehand. This reduces the data volume that needs to be cloned, significantly speeding up the process. Follow the step-by-step guide below to clone your laptop's HDD to an SSD or a larger HDD using Hasleo Disk Clone.

Step 1. If your laptop lacks a second drive bay, connect the SSD or larger HDD externally via a SATA-to-USB adapter cable. Verify that Windows recognizes the drive.

* Tips: Before use, a new hard drive may need to be initialized in Windows Disk Management

Step 2. Download, install, and run Hasleo Disk Clone. Click the "Disk Clone" button. Then select your current hard drive (usually Disk 0) as the source disk and click "Next".

How to replace an HDD with an SSD or larger HDD?

Before proceeding, ensure the cloning operation has completed successfully. Then, follow the steps below to replace the original HDD with the new disk.

Step 1. Shut down the laptop. Disconnect the power supply and all external devices, including the newly connected SSD or new HDD.

Step 2. Position the laptop with the bottom side facing up. Locate and remove the screws on the bottom cover using a small screwdriver. If the battery is removable, disconnect it at this time.

* Tips: Screw layout varies by model. It's highly recommended to find a specific guide for your laptop before proceeding.

Step 3. Locate the original hard drive (typically a 2.5-inch model) mounted on a bracket. Remove the bracket's mounting screws, then remove the hard drive.

Step 4. Install the cloned SSD or larger HDD into the original drive bracket. Then, ensure it is securely connected to the motherboard.

Step 5. Reassemble the laptop, replace the back cover, and tighten all screws.

* Tips:

  1. For laptops with dual drive bays, you can install an SSD or a larger HDD into the empty bay while leaving the old HDD in place. After installation, set the new SSD/HDD as the boot drive in the UEFI/BIOS settings. Depending on your needs, the original HDD can serve as a backup boot drive or a data storage drive.
  2. If the empty bay is an M.2 slot, only an M.2 SSD will fit.
  3. To remove the M.2 SSD: Unscrew the retaining screw at the rear end, then gently pry up and remove the drive. To install: Insert it into the M.2 slot at a 30-degree angle, then press it down and secure it by tightening the screw.

How to boot from the replaced SSD or larger HDD?

Before continuing, ensure your laptop is fully and correctly reassembled. Once the SSD or new HDD is installed, follow the steps below to boot from it.

Step 1. Connect the power supply, turn on the laptop, and immediately press the F2, Del, F10, or Esc key repeatedly to enter the UEFI/BIOS setup menu.

* Tips: For the correct key, please refer to your laptop's manual or the on-screen prompt in the lower-left or lower-right corner during startup.

Step 2. Navigate to the Boot tab, set the SSD or larger HDD as the first boot device, and save the changes.

Step 3. Restart your laptop and boot from the newly installed SSD or HDD.
