Spec? We go specs. Includes an AMD Ryzen 9, 16GB of RAM, a 1TB SSD, an NVIDIA GeForce RTX 3060 in a 14" display with QHD 1440p resolution and a 160Hz refresh rate.

There’s one important fact you’ll need to keep in mind when cloning drives like this. Your new SSD has to be big enough to hold everything from your older, primary hard drive. If that’s not the case, cloning won’t work.

To free up space, you can delete files you no longer need or can re-download again. You can also install a fresh version of Windows on the new SSD, make that the primary boot drive (via your motherboard’s BIOS), and use your older hard drive as secondary storage for your less-critical files, games, movies, or whatever. You don’t have to have everything on your new SSD, after all.


4. Copying the System Reserved partition

This section explains in detail how to copy System Reserved partition from HDD to SSD using Emergency Boot Kit Partition Manager.

1. Choose “Direct copy: partition-to-partition or disk-to-disk” in the menu of Emergency Boot Kit partition manager:

2. Choose source partition on the HDD and destination partition on the SSD. Both of them must correspond to System Reserved partition about 100MB in size:

3. Wait until the following window appears and click OK:

Note destination partition volume label changed in the “Existing Partitions” list in the menu of Emergency Boot Kit partition manager.


Disk Installation

Once you’ve got the old disk cloned onto the new one, then you should be ready to complete the installation of the new drive! You’ll need to remove the old drive, of course – keep it safe, however.

Fingers crossed this should work without a hitch – but if there are problems in installation, you’ll be glad to have your old disk around. You’ll at least be able to get back into a working computer and diagnose the problem!

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.

Boot Your PC from the New SSD

After finishing the SSD installation, there is another thing you should do and that is you need to tell the computer to boot from it.

Note: For a PC with only one hard drive, this is not necessary. But if you keep two hard drives, you need to do this work.

Reboot your computer to enter its BIOS menu by pressing a specific key. Based on different computer brands, the key is different and it can be Del, F2, F10, F12, etc. For more information, refer to this post – .

Then in the BIOS menu, look for the boot options. Also, they are in a different place depending on the PC. Next, change the first boot sequence to the SSD, save the change and your computer will run from the SSD at a fast speed. Now, the machine will be significantly snappier without having to reinstall a thing.

Migrate Your Windows 10 to SSD Without Reinstalling

I am going to show you two different ways to perform the migration. Both of them are very easy to perform. Either of them should work perfectly.

A Little Heads-up

A Little Heads-up

Before starting the migration process on your Windows 10, the SSD drive of yours needs to be formatted properly. If not, you may face some problems and the migration may not be done perfectly which later may cause some issues.

Furthermore, you might want to keep a backup of your operating system, if something goes wrong in the mid-way, you might lose your valuable data and all of this would be for nothing. So, keeping a backup of your C drive and operating system is a safe measurement.

If your operating system drive occupies a larger space than your SSD capacity then you need to delete some unnecessary files and software to free up some space and make your operating system’s drive to occupy less space.

Method 1: Direct Copy

Copying is the operating system from your old HDD to the new SSD is a comparatively safe, fast, and easy way to perform the migration.

Unlike regular copying performance, copying the operating system can not be done that simply. It can be done with the software iSumsoft Cloner that I have mentioned earlier.

Step 1: Download and install iSumsoft Cloner.

Step2: Open and launch the iSumsoft Cloner. After launching this software, it will automatically detect all of your active drives on your computer including your Solid-State Drive or SSD, and show them on the screen.

Step 3: Click on the Copy option. You can see it on the pane on the left side of the software window.

Step 4: Then you will see “Select a source target”. Go there and select the system partition which is usually the C drive of your HDD. This is the drive on which your operating system is currently installed.

Step 5: After selecting the target source now it is time to set up the destination folder. Go to “Select destination target” and select your SSD partition to which you will migrate or move the operating system from your HDD.

Step 6: Click start and a tips dialogue will pop-up. Click ok and proceed. The copying will start and it will take some time.

Wait till the copying process finishes and you are done.

Step 7: Now restart your computer and access the BIOS settings and set the SSD as your first boot device. Then exit the BIOS Settings and it is done.

Now your computer will perfectly work as it used to work before.

Method 2: Backup and Restore

The previous method was based on a direct copy via the software called iSumsoft Cloner. This is another method to copy your Windows 10 operating system from HDD to SSD without reinstalling. This the backup and restore method using the same software that we have used in the previous method.

Note: This method is a bit complicated and risky compared to the previous method.

In case the first method did not work for you then try this method by following the steps below:

Step 1: Make sure to have a backup of the Windows 10 operating system. Then open and launch iSumsoft Cloner, then click on the Backup option and then select the partition that contains your Windows 10 operating system. Usually, it is the C drive of your hard disk.

Then select a path to save the backup on your computer. Save it on the hard disk so that the backup file does not occupy your limited SSD space.

Then Click Start to start the process. A dialogue box will popup click ok and proceed to start the backup process of your operating system.

Wait for a few minutes until the backup process is finished. You will see a popup saying mission completed.

To make sure the backup is done correctly go to the selected path and you will see a .icg file in the selected location of your hard disk.

Step 2: Now it is time to restore the backup of your operating system to the SDD.

Go to the iSumsoft Cloner and launch the software again. Then select the Restore option from there.

Click Choose and select the backup file you just created in the last step. After that select the SSD partition to which you want to migrate your Windows 10 operating system from “Select the restoration destination”.

After that hit “Start” and a dialogue box will pop up. Hit ok and proceed. Wait for a few minutes for the restoring process to be finished.

Step 3: Finally, restart your computer and enter the BIOS settings. Set the volume from the SSD drive to boot your computer.

When it is done, your computer will work perfectly as if nothing happened.

These are two ways to migrate your Windows 10 operating system from your old HDD to a newly installed SSD without reinstalling the whole operating system. Also, you can do a system restore for your Windows OS so that you can always come back to a previous stable state.

Have a great day.

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.)
