Cloning is the process of making an exact copy of your old hard drive – including Windows, all your installed programs, settings and personal files – onto a new SSD. Once cloned, you simply swap the drives over and your PC boots up exactly as before, just dramatically faster. No reinstalling Windows, no re-downloading programs, no re-entering licence keys.

Key takeaway: Free cloning software lets you copy your entire HDD to a new SSD in one go, keeping Windows and all your files intact without a fresh install.

What you'll need

  1. A new SSD large enough to hold your existing data (check how much space is currently used on your old drive first).
  2. Free cloning software: Macrium Reflect Free, or the manufacturer's own tool if you bought a Crucial or Samsung SSD (Crucial's tools work with Acronis True Image for Crucial, and Samsung Data Migration works with Samsung drives).
  3. A way to connect the new SSD to your PC temporarily – either a spare drive bay, or a USB-to-SATA cable/enclosure (a few pounds online) if you only have one drive bay, as is common in laptops.
  4. A Phillips #0 or #1 screwdriver for opening your case or laptop.
  5. A full backup of your important files to an external drive or cloud storage, as an extra safety net.

Before you start: Cloning is generally safe, but things can occasionally go wrong (power cuts, faulty cables). Always back up your irreplaceable files separately before you begin, and check your laptop's warranty status if it is still covered, as opening the case may affect it.

Step-by-step cloning process

  1. Connect the new SSD: Plug your new SSD into your PC via a spare SATA port and power cable, or connect it externally using a USB-to-SATA adaptor cable.
  2. Install your cloning software: Download and install Macrium Reflect Free (or your SSD manufacturer's own migration tool) while your PC is running normally from the old drive.
  3. Select the source and destination: Open the software and choose your old HDD as the source drive and the new SSD as the destination. Double-check you have this the right way round, as cloning overwrites the destination drive completely.
  4. Start the clone: Begin the cloning process. Depending on how much data you have, this can take anywhere from 20 minutes to a few hours – leave the PC alone and don't interrupt it.
  5. Verify the clone completed successfully: Most software will confirm the clone finished without errors. If any errors are reported, don't proceed – troubleshoot or try again first.
  6. Power off and unplug: Shut the PC down completely, unplug it from the mains, and hold the power button for a few seconds to discharge any residual electricity before opening the case.
  7. Swap the drives: Remove the old HDD and fit the new SSD in its place, using an anti-static wrist strap or regularly touching bare metal on the case if you don't have one, to avoid static damage to components.
  8. Boot up and check: Reconnect everything, power on, and confirm Windows starts normally with all your files and programs present.

Tip: If your new SSD is smaller in capacity than your old HDD (for example moving from a 1TB HDD to a 500GB SSD), most cloning tools let you resize partitions during the process – just make sure your used data will actually fit first.

Frequently asked questions

Is cloning free to do?
Yes. Macrium Reflect Free and most SSD manufacturers' migration tools are free to download and use for this exact purpose.
What if my laptop only has room for one drive?
Use a cheap USB-to-SATA cable or external enclosure to connect the new SSD temporarily for cloning, then swap it in for the old drive once the clone is verified as complete.
Can I keep my old hard drive as extra storage afterwards?
Yes, once cloned you can reformat the old HDD and use it as external storage via a USB enclosure, or keep it untouched as a backup for a little while just in case.
