How to Migrate Windows 10 to SSD without Reinstalling OS?

How to transfer an OS to SSD? Actually, it is not as difficult as a lot of people think as long as a piece of professional third-party app could be available to help. In this article, we are going to show you some necessary clone processes to transfer Windows from HDD drive to SSD properly with a diskpart manager. 


Before you clone Windows 10 to SSD without reinstalling OS, there are some things you need to note for this migration or clone job.

  1. Prepare an SSD as the target disk. Please note the disk space of SSD can’t be smaller than the used space of the source disk.
  2. Possess a cloning tool. In the software market, many kinds of cloning tools are provided. Here we will show you the best SSD cloning software for Windows 10 – MiniTool Partition Wizard.


How do I reinstall Windows 10 on my SSD?

Save your settings, reboot your computer and you should now be able to install Windows 10.

  • Step 1 – Enter your computer’s BIOS.
  • Step 2 – Set your computer to boot from DVD or USB.
  • Step 3 – Choose the Windows 10 clean install option.
  • Step 4 – How to find your Windows 10 license key.
  • Step 5 – Select your hard disk or SSD.

Why Migrate Windows 10 to SSD

Now two pieces of best SSD upgrade software Windows 10 has been introduced. Some of you probably want to know the reason for transferring your OS to SSD. Here let’s analyze this question in two aspects and help you learn OS migration to SSD well.

 Why Use SSD for OS Disk

If your computer is struggling to load some large files or documents and run many applications at the same time or you want to speed some things up a little, upgrading your old HDD drive to a solid state drive (SSD) is the surest way. Why?

It is because of the merits of SSD. Compared to HDD, SSD has many advantages, for example, it doesn’t have noise and moving parts, it is less likely to get damaged. Above all, the read-write speed of SSD is very fast. In order to speed up your computer, using an SSD as OS disk will be a good choice.

 Why Do OS Migration

Suppose you have installed Windows 10 on an HDD, but now you want to boot your computer from SSD for the best performance. In this case, usually, the simplest way is to perform a clean installation on the SSD. Nevertheless, this way is not the best solution. What’s the reason?

In a word, OS fresh installtion is very time-consuming and troublesome since you need to install applications once again and data saved on C drive will be lost.

If you wouldn’t like to make a fresh OS installation on an SSD, there is a way to move the already installed Windows 10 to SSD without reinstalling OS. You can choose to migrate Windows 10 to SSD.

Note: After reading so much information, some of you may ask: how to install an SSD without reinstalling Windows? As for this topic, you can also connect the SSD to your computer and then use MiniTool software to move Windows 10 to SSD or clone HDD to SSD to do this work.

Step one: Grab Macrium Reflect (free edition)

We’ll be using the application Macrium Reflect to clone your hard drive to your new SSD. When you double-click on the installer, you’ll actually see a screen that looks like a downloading tool rather than your typical application installer. That’s correct. I’m not sure why Macrium Software goes this route instead of just offering up the entire app as a download, but there you go.

You shouldn’t have to change any options on this screen. Just click the “Download” button and follow all the prompts when it has completed. Once Macrium Reflect loads up, and assuming your new SSD is connected to your desktop or laptop, you’ll see a screen that looks something like this:

For the purposes of this article, I’ll be wiping my F:\ drive (“Tiny Game Drive”) and pretending I’m cloning my primary drive, C:\, over to it. (I accidentally deleted my screenshot that showed F:\ as empty, so let’s play pretend for a moment.)

Step four: Finishing up your drive install

Now that you have a clone of your original drive, don’t do anything on your primary drive that puts data on your computer you’d otherwise want to save, because that won’t appear on your cloned drive. I recommend placing a text file on your desktop that says “THIS IS THE OLD HARD DRIVE,” or something more witty than that, and then power down your computer.


If you’re replacing your old hard drive with your new SSD, disconnect your old hard drive from your desktop or laptop (likely a SATA and power cable) and plug in your new SSD right where your old drive used to be. You shouldn’t have to tweak anything else in your system’s BIOS—it should boot directly to your primary Windows partition on your new SSD. (Or, at least, mine did.)

If you’re keeping your old hard drive around, reconnect it to another SATA port on your desktop system. Check to make sure your computer doesn’t accidentally boot to it instead of your new SSD by seeing if the total size of your c:\ drive (in bytes, in its “Properties” screen) matches the capacity of your new SSD, not your old hard drive. That, or look for the “THIS IS THE OLD HARD DRIVE” text file on your BIOS, assuming you didn’t skip that step. If you’re booting to your old hard drive instead of your new one, you’ll have to change your system’s boot order in your BIOS.


Assuming that your computer is correctly booting to your new SSD, pull up Computer Management (via the Start Menu), click on Disk Management, find your old hard drive, right-click on its various partitions, and select “Delete Volume” for each one. If this option is grayed out, you might need to use a third-party app like Paragon Hard Disk Manager (the free version) instead. Same concept, it’ll just allow you to delete your old volumes and re-partition the drive as a big fat chunk of empty space.

Another Way: Install Windows 10 on New SSD

If you don’t want to use the original operating system, you can choose to perform a clean install of Windows 10 on the new SSD. Here, Media Creation Tool can be used to perform this work. Just get it from the Internet and create a bootable USB flash drive. Next, boot the PC from the USB drive and start the clean install.

Steps to install SSD in laptop without reinstalling OS

To install SSD for replacing the old hard drive without reinstalling OS and other applications, you need to first transfer all data from HDD to the target solid-state drive, then remove the old HDD and install SSD into laptop to make it boot from the destination disk. The whole process can be divided into the following three steps:

Step 2. Install SSD drive to laptop

Once cloning is accomplished, all data on the original disk has been migrated to the SSD drive. Now, please take below steps to install the SSD drive into your laptop to replace the old hard drive.

2.1. Turn off your laptop; disconnect SSD drive, power cable and other connected cables. Place your laptop upside-down.

2.2. You should see a plastic cut-out panel in the bottom which is covered by several screws. Now remove them using a screwdriver. If your laptop has no cut-out, you need to take the entire bottom off to get access to your old hard drive.

2.3. Unscrew all screws that are used to secure your HDD to your laptop.

2.4. Lift the old drive up about 30 or 45 degrees and pull it out.

2.5. Now, you can install the SSD by doing the reverse of uninstalling the HDD. Please slide the solid-state drive in at an angle and push it correctly into place.

2.6. Then secure it with the screws you removed before. At last, screw the back panel covering the drive back on.

Step 3. Boot laptop from SSD drive

Now, you can enter BIOS environment to change boot order to make laptop boot from SSD drive.

3.1. Reboot the laptop and long press ESC, F1,F2, F8 or F10 during the initial startup screen. Then Boot menu will appear.

3.2. Use the arrow keys to access to the Boot tab. System devices will appear in order of priority.

3.3. To give the cloned SSD drive boot sequence priority over the hard drive, just move it to the first position in the list.

3.4. Save and exit the BIOS setup utility. And your laptop will restart with the changed settings.

If the cloned SSD won’t boot, you can check whether the boot mode (BIOS or UEFI) is proper, and the system files are complete.

Step Three: Clone Your Drive With EaseUS Todo Backup

Now it’s finally time for the main event. Fire up the EaseUS application and click “Clone” on the main screen.


First, select your source disk. This will be  your current Windows system drive. Our system drive consists of three partitions: an active boot partition, the actual Windows partition, and a recovery partition. We want to clone all three, so we’re just going to place a check next to the hard disk to make sure they’re all selected. Click “Next” to proceed.

Now you need to select your SSD as the destination

Now you need to select your SSD as the destination. In our case, that’s “Hard Disk 4”, containing 119 GB of unallocated space. Make absolutely sure you choose the correct drive, or you could lose data!

Place a check by it, and then check the “Optimize for SSD” box, which will ensure you get the best performance possible out of your resulting Windows installation.

Now, before you click “Next”, take a m

Now, before you click “Next”, take a minute to click the “Edit” button next to your SSD.

EaseUS will show you what your resulting drive wil

EaseUS will show you what your resulting drive will look like. In some cases, you may need to do some tweaking here. For example, on my SSD, EaseUS wanted to make the boot and recovery partitions much larger, even though they contain less than a gigabyte of data. I’d rather have that space on my main Windows partition, so I needed to resize these before continuing.

To resize these partitions, first select one, then

To resize these partitions, first select one, then drag the handles that appear between the partitions, much as if you were resizing a File Explorer window.



I then resized my main Windows partition to fill the rest of the empty space.

Depending on your drive’s layout, you may ha

Depending on your drive’s layout, you may have to alter things in a different way. When you’re done, click “OK” to continue. Double-check that everything looks right, and click “Proceed” to start the clone operation.

If you get the following warning, click “OK&

If you get the following warning, click “OK” to continue.

The actual length of the operation will depend on

The actual length of the operation will depend on how big your source drive is, as well as the speed of the storage mediums and your computer. For us, it took about 10 minutes.

If you run into any errors during this process, you may need to use a third-party defragmenting tool on your current system drive—in some cases, system files sitting on the end of a drive can make it difficult to resize.

When the operation is completed, click “Finish”.

As you can see in the following screenshot, our new system drive is already showing up in File Explorer. All that’s left now is to begin using it.



To do this, the next steps are fairly simple. Shut down your computer, remove the old drive and install the new in the same place. Restart your computer and it should boot from your new drive automatically.

If you’re using a desktop computer and want to leave the old drive in place—perhaps as a backup or storage device—then you will need to boot into your system BIOS (usually by holding the Delete button before the Windows boot logo appears). From there you will need to point your BIOS at the new drive as the first one to boot. You can follow our instructions on booting from USB to do this—just select your new hard drive instead of a disc or USB drive in the instructions.

In either case, when you reboot, you should find that your SSD is now listed as the C: drive. (If it isn’t, double-check you performed the above steps correctly.)
