Ⅰ. Introduction: Why Move Windows 11/10/8.1/7 OS to SSD

If you have bought a new solid-state drive (SSD), it's time for an upgrade. Your computer will boot much faster if you move Windows installation to the SSD, especially if you have an older and slower HDD. Why? That's because traditional hard drives are essentially metal platters with magnetic coatings that store your data, with a read/write head on an arm that accesses the data while the platters are spinning. A solid-state drive performs the same basic function as a hard drive, but data is instead stored on interconnected NAND flash memory chips.

Compared with hard drives, SSDs have many advantages:

  • Much faster data access speed
  • Lower power consumption
  • Better reliability (no moving parts)
  • Shock resistance

Therefore, it's a great idea to move OS to a new hard drive or SSD. By doing so, you can improve your computer's performance by a large margin. 

There are generally two ways to move and install OS to SSD: 

  1. 1. Clone OS disk to SSD with third-party Windows OS migration software
  2. 2. Clean install from a Windows bootable media created by Microsoft

Ⅱ. Migrate OS or Clean Install: Which Suits You Better?

If you're looking for a hassle-free way to move your OS installation to an SSD, cloning is the way to go. This will create an exact replica of your current system on the new drive, including all your personal files and all currently installed programs. 

The second method: clean install Windows 10 from scratch, gives you a completely fresh start. If you choose this route, you'll have to reinstall all your programs and copy over any personal data you want to keep. The upside is that everything will be nice and clean, with no junk files or unwanted programs cluttering up your system. 

To help you make a decision, here are the pros and cons of each method:

1. Clone Windows 10 to SSD

✔ Pros:

  1. 1. Saves time: All your programs and files will be copied over to the new drive automatically.
  2. 2. Keeps everything intact: Your personal files, preferences, and programs will all be exactly the same as they were on your old hard drive.
  3. 3. No need to reinstall Windows: You won't have to go through the trouble of a clean install and set up everything from scratch.

✘ Cons: 

  1. 1. Requires a lot of free space: In order for this method to work, you'll need enough free space on your SSD for an exact copy of everything on your current hard drive. 
  2. 2. Cannot exclude programs and files in the system disk: When you clone a system drive (unless you do a clean before migration), you clone all contents along with the operating system to the destination drive.

2. Clean Install Windows 10 on SSD

✔ Pros:

  1. 1. Gives you a fresh start: A clean install will remove all the files and programs from your current hard drive, giving you a blank slate to work with. 
  2. 2. Ensures compatibility: This method is more likely to ensure that all your programs will work properly on your new SSD. 

✘ Cons: 

  1. 1. Takes longer: You'll have to go through the trouble of reinstalling all your programs and copying over your personal data. 
  2. 2. Requires reinstalling programs, games and moving personal data:  You'll have to do a bit of work to get everything set up again the way you want it. 

So, to sum up,  if you just want to move Windows 10 to your new SSD with the least amount of hassle, cloning is the way to go. But if you're looking for a clean slate, or if you're having compatibility issues with your programs, a clean install might be a better option.

Note*: Why is it important to do 4k alignment if clone OS from HDD to SSD?

The 4k alignment refers to the way data is organized on a solid-state drive, and specifically to the alignment of data at 4-kilobyte boundaries. Data that is not properly aligned can cause performance degradation on an SSD.

Ⅳ. Additional Tip: How to Migrate OS to SSD Without Cloning?

The only way to move OS to SSD without cloning is with the help of the Windows media creation tool. It is a free program from Microsoft that allows you to create a bootable USB drive or DVD with the Windows 10 installation files. This is useful if you want to install Windows 10 on a new hard drive or SSD, or if you want to create a backup installation disk. However, this method has several disadvantages. 

  1. First of all, it takes a long time since you have to reinstall the operating system and programs from scratch. 
  2. Secondly, it's more complicated than using cloning software and there's a greater chance that something will go wrong. 
  3. Finally, you'll lose any personal files or data that isn't backed up, so make sure you have everything you need before starting. 

If you're willing to take on challenges, however, here are the detailed steps: 

Step 1. Go to Microsoft's website and download the Windows Media Creation Tool for Windows 11, Windows 10, Windows 8.1, and Windows 7.

Step 2. After downloading Windows 10, for example., run the tool and select "Create installation media for another PC".

Step 3. Choose your preferred language, edition and architecture (64-bit or 32-bit). 

Step 4. Select "USB flash drive" as the media to use and click "Next".

Step 5. Choose the drive you want to use and click "Next". 

Step 6. Wait for the process to finish and then move on to the next section. 

Step 7. Boot from the USB drive you created and follow the prompts to install Windows 10 on your SSD. 

Step 8. When asked, select "Custom: Install Windows only (advanced)". 

Step 9. Choose the SSD as the location to install Windows 10 and continue with the installation process. 

Step 10. Once everything is finished, you'll have a clean install of Windows 10 on your new SSD!

Ⅴ. How to Boot from SSD After OS Migration or Manual Install

After you move Windows 10 to SSD or perform a clean install, you'll need to change the boot order in your BIOS to make sure your computer boots from the SSD. 

Step 1. Restart your computer and enter the BIOS. This is usually done by pressing F2, F12, DEL, or ESC when your computer first starts up. 

Step 2. Find the "Boot Order" or "Boot Priority" setting and change it so that your SSD is listed first.

Step 3. Save your changes and exit the BIOS. Your computer should now boot from the SSD! 


Still curious about how to enter the BIOS or change the boot order on your particular computer? Try to follow this comprehensive guide on how to boot from SSD, even if you come across tricky issues like cloned SSD won't boot, this guide got you covered.

Ⅵ. Hard Drive Retention Advice After Clone

Once you move Windows 10 to SSD, the old hard drive can be used as a data disk. If your computer only has one hard drive bay, you'll need to use an external hard drive enclosure or USB adapter to connect it to your computer. 

If you're not sure what to do with your old hard drive, we have some advice on what you can do with an extra hard drive. 

  1. 1. Use it as a backup drive 
  2. 2. Give it to someone else 
  3. 3. Sell it online 
  4. 4. Use it as a media server 
  5. 5. Donate it to a school or library 
  6. 6. Use it for storage 
  7. 7. Recycle it  


Unless you set up your mind using only one hard drive in your computer, try to make full use of the old bigger hard drive and the new faster SSD together. Read through the 1+1>2 solution to use HDD and SSD together, and you'll clearly know the benefits in practical use.

Ⅶ. Wrapping Things Up 

Now you know how to move Windows 10 to SSD without reinstalling the operating system or losing any data! This is the easiest and quickest way to upgrade your hard drive to an SSD, and it will make your computer much faster in the process. With the right tool like EaseUS cloning software, it's not difficult to do, and we hope this guide has helped you out.
