High-speed M.2 drive that fits most modern laptops and desktops for a major performance boost.
Cloning kit lets you copy your current Windows setup directly to the new drive without reinstalling.
Before you start: Back up and prepare
Your files are on the old drive. The new SSD is empty. If you install Windows now, you will need your old data to restore it later. The other half of this decision is stuck mouse cursor.
Connect the old drive or have a backup ready. Use Windows File Explorer to copy your Documents, Desktop, and important folders to an external drive or cloud storage.
Once your data is safe, shut down the computer completely. Unplug the power adapter and disconnect the battery if you are working on a laptop.
- Backup: Copy personal files to an external drive.
- Power: Disconnect AC power and internal battery.
- Tools: Have a USB stick ready for the Windows installer.
Safety first: Always disconnect the battery before opening a laptop case to prevent short circuits.
What you need to install Windows 11
You need a few specific items before you start. The most important is a USB drive with at least 8GB of space. You will use this to install the operating system.
You also need the physical SSD. Most modern computers use M.2 NVMe drives, but some use SATA. Check which one fits your computer before buying.
If you do not have a USB stick with Windows already, you can download the Windows 11 installation media from Microsoft’s website and create it on a spare USB drive. Loaders in this spot often ask about fixing post-update sound glitches as well.
- USB Drive: 8GB or larger for the installer.
- SSD: M.2 NVMe or SATA, depending on your model.
- Phillips Screwdriver: For opening the case and mounting the drive.
This M.2 NVMe drive is compatible with most modern systems and offers the speed needed for a snappy Windows 11 experience.

The job at a glance: Time and difficulty
The full process is straightforward but requires careful attention to detail. Here is what to expect.
| Step | Difficulty | Time |
|---|---|---|
| Install new SSD into computer | Easy | 10 mins |
| Create Bootable USB (if needed) | Easy | 15 mins |
| Boot from USB and Install Windows | Medium | 30 mins |
| Restore Files and Drivers | Easy | 20 mins |
Total time is under an hour for most users. The hardest part is usually booting from the USB drive.
Step-by-Step: Install Windows 11 on the new SSD
Follow these steps in order. Do not skip the boot menu step, as this is where most people get stuck.
- Insert the SSD: Install your new SSD into the empty slot on your motherboard.
- Insert the USB: Plug your Windows 11 USB drive into the computer.
- Enter BIOS: Turn on the PC and press F2, F10, or Del to enter BIOS/UEFI settings.
- Set Boot Order: Find the Boot section and move the USB drive to the top of the list.
- Start Installation: Save and Exit. The PC will restart into the Windows installer. Follow the prompts to erase the SSD and install Windows.
If you see a ‘No Bootable Device’ error, double-check that the USB is fully inserted and that you selected the correct drive in the BIOS.
Pro tip: If your computer uses UEFI, make sure Secure Boot is enabled and the USB is formatted as GPT.
Test it: How to tell if it worked
After installation, you will see the Windows 11 setup screen. This is a good sign. For the detail, see our notes on fixing connection instability.
Once you reach the desktop, open ‘This PC’. You should see your new SSD listed as the C: drive. The capacity should match the size of the SSD you installed.
Right-click the C: drive and select Properties. If the health status says ‘Good’, the drive is working correctly. Restart the computer one more time. If it boots straight into Windows without the USB plugged in, the installation is complete.
When to get it repaired instead
Most users can do this themselves. However, there are signs that point to a deeper issue.
If the computer does not detect the new SSD in the BIOS at all, there may be a problem with the slot or the motherboard. This is a hardware fault that requires a professional.
Reinstallation at a service center usually costs in the mid-price tier. If you are uncomfortable opening the case or dealing with BIOS settings, a technician can handle the hardware installation and ensure the drive is properly seated.
Safety first: Do not force the SSD into the slot. If it does not slide in easily, stop and check the alignment.
Frequently Asked Questions
Can I skip the USB installer and just clone my old drive?
Yes. Cloning software copies your existing Windows setup to the new SSD. This saves you from reinstalling, but you must have a SATA to USB adapter for older drives. If you are buying a new M.2 drive, cloning is still possible but requires a specific cable.
Will I lose my files during the reinstall?
You will lose files that are currently on the new SSD. Since the new SSD is empty, you need to restore your files from a backup or your old drive. Always back up your important data before starting.
Do I need to activate Windows 11 again?
If you had Windows 11 on the old drive, the license is often linked to your Microsoft account or motherboard. It should activate automatically. If not, you can use your product key to activate it manually.
The bottom line
For most people, buying a compatible M.2 SSD and installing Windows 11 from a USB drive is the fastest and cheapest path. If you want to keep your exact settings without reinstalling, look into cloning, but the standard reinstall is the most reliable method. Start by backing up your files, then follow the boot order steps in the BIOS.

Frequently asked questions
Can I just clone my old drive to the new SSD?
Yes, cloning copies your entire system, so you don’t have to reinstall Windows. This is faster if you have the right cables. However, if you are moving from a mechanical hard drive to an NVMe SSD, you need a specific adapter to connect the old drive during the cloning process.
How much space do I need on the USB drive?
You need a USB drive with at least 8GB of free space. A 16GB or 32GB stick is a good choice because it gives you room for the installer and any other tools you might need later.
What if my computer doesn't boot from the USB?
This is the most common issue. You likely need to enter the BIOS (usually by pressing F2, F10, or Del at startup) and change the boot order to prioritize the USB drive. Some computers have a one-time boot menu you can access by pressing a specific key, often F12.
Do I need to install drivers after reinstalling Windows?
Windows 11 usually finds and installs most basic drivers automatically, like your network card and basic display. You may need to manually install drivers for specific hardware like a sound card, Wi-Fi adapter, or GPU for best performance. Check your computer manufacturer’s website for the specific driver packs.
