Upgrading your M.2 SSD to a larger drive is essential for expanding storage or replacing aging hardware. Whether you’re moving OS to new M.2 in laptop or upgrading a desktop, cloning ensures seamless data migration without reinstalling Windows. This guide also addresses advanced scenarios like clone NVMe SSD to NVMe SSD and install Windows 7 on NVMe SSD for legacy systems.
Part 1: Prepare M.2 SSD
Cloning a hard drive to an SSD enhances your computer’s performance without requiring a Windows reinstallation or risking data loss. This process applies equally when upgrading to a larger M.2 SSD. To ensure a smooth transition, follow these preparatory steps for your new M.2 SSD:
Step 1. Verify SSD Slot Availability
- Open your laptop or desktop case using a screwdriver.
- Inspect the number of available M.2 SSD slots.
Note: If your device lacks sufficient slots, refer to specialized methods for cloning with a single slot.
Step 2. Select the Correct M.2 SSD
When purchasing a new M.2 SSD, prioritize these factors:
- Ensure the SSD matches the length of your PC’s slot.
- For single-slot systems: Acquire an M.2 SSD USB adapter alongside the new drive.
- Opt for a capacity 2–3 times larger than the original SSD (e.g., 500GB or 1TB models).
Step 3. Install the New M.2 SSD
- For single-slot PCs: Connect the SSD via the USB adapter.
- For multi-slot systems:
- Laptops: Open the M.2 slot → Insert the SSD → Secure with screws → Reattach the cover.
- Desktops: Locate the PCIe-labeled M.2 connector → Insert the SSD → Fasten with the mounting screw.

Step 4. Initialize the New SSD
To prepare for cloning:
- Open Disk Management and right-click the original SSD → Check its partition style (MBR/GPT).
- Right-click the new SSD → Select “Initialize Disk” → Match the partition style to the source drive.
With these steps completed, you’re ready to proceed with cloning your M.2 SSD or transferring data between drives efficiently.

Step 2: Choose Source Disk
Next, select the source disk or SD card you want to clone. The software will display the layout of the selected disk at the top of the list view for easy reference.
Important Notes:
- Sector by Sector Clone: Use this option if your source disk has bad sectors or a damaged file system. It ensures every sector is copied, including damaged ones.
- Skip Bad Sectors: If your source disk has bad sectors, this option allows the software to clone only the healthy sectors, making it ideal for older disks.
Step 3: Choose Destination Disk
Now, select the destination disk or SD card where the cloned data will be stored. Ensure the target disk has enough storage capacity to accommodate the data from the source disk.
Step 4: Start the Cloning Process
Once you’ve selected the source and destination disks, review the settings and click “Start Clone”. The software will handle the rest, ensuring a seamless and accurate cloning process.
Part 3: What to Do After Cloning M.2 to M.2 SSD
#1. Make Cloned M.2 SSD Bootable
- Restart your PC and enter BIOS (press F2/DEL).
- Set the cloned SSD as the primary boot device.
- Disable Secure Boot temporarily if Windows fails to start.
#2. Manage Old M.2 SSD
- Repurpose it: Use the old SSD as external storage via an M.2 enclosure.
- Secure erase: Use tools like DiskPart to wipe sensitive data before disposal.
FAQ About M.2 SSD Clone
1. Can I clone an M.2 SSD with only one slot?
Yes! Use a USB-to-M.2 adapter to connect the new SSD externally, then clone with WittyTool.
2. Will cloning affect Secure Boot?
Temporarily disable Secure Boot in BIOS during cloning, then re-enable it afterward.
3. Do I need to format a new SSD before cloning?
Yes. Formatting ensures compatibility and prepares the drive for data transfer.
