Currently, all new programs are getting installed by default on the C drive. I do not have the option to choose where they will be installed. How to change my primary hard drive on Windows 10 from C drive to the larger SSD? Thank you!

In the ever-evolving landscape of technology, adapting our systems to meet growing demands is essential. One such demand often faced by Windows 10 users is the need to change their primary hard drive. While this might seem like a complex task, fear not! This guide is here to walk you through the process step by step, making the transition smooth and hassle-free.

How to Change Primary Hard Drive on Windows 10/11

For how to change default hard drive on Windows 11/10, the following is a step-by-step guide for you.

Step 1: Backup Your Data

Before embarking on the journey of changing your primary hard drive, it's crucial to backup your data. Even though the process we'll discuss is designed to minimize risks, it's always wise to have a backup.

Step 2: Identify Your New Primary Drive

Once your data is securely backed up, it's time to identify and prepare your new primary hard drive. Ensure it has enough space for your files and works with your system. Also, consider the type of port (SATA, PCIe, etc.), and the form factor (2.5-inch or M.2).

Step 3: Transfer the Operating System

The heart of the process lies in transferring your operating system to the new drive. AOMEI Backupper Professional simplifies this step with its intuitive features.

  • Disk Clone or System Clone: You can choose to copy the entire hard drive or only OS. Choose System Clone if the new hard drive doesn’t have enough capacity to hold all data on the old hard drive.

  • Intelligent Clone: This feature detects the used sectors of the source disk and only clones the data in use, excluding any empty sectors.

  • Bootable Clone: AOMEI Backupper ensures that the cloned drive can boot the operating system without needing additional configuration or installation.

  • Supported Devices: A wide range of storage devices are supported, including SATA/IDE HDDs, SATA/NVMe SSDs and USB flash drives, etc.

Follow these steps to learn how to transfer OS from one hard drive to another:

1. Connect the new hard drive/SSD to your computer. Open AOMEI Backupper and click on “Clone,” then select “System Clone.”

2. The necessary system partition(s) will be automatically selected. Choose the target disk you connected and click “Next.”

3. Customize the cloning process as necessary. Finally, click “Start Clone” to begin OS migration.

  • Make full use of disk space: If you are currently cloning OS to larger hard drive, it can extend the size of your system partition by using adjacent unallocated space.
  • SSD Alignment: If you are migrating operating system to SSD, you can check it to improve SSD’s performance and prolong its lifespan.
  • Sector By Sector Clone: It applies to copy all the sectors no matter used or not. If you want to migrate OS to new drive with only used sectors copied, just keep the default intelligent mode.

This process may take some time, depending on the size of your system files, so be patient. Once completed, you'll have a mirrored version of your operating system on the new drive.

Step 4: Replace Old Hard Drive and Boot

If you want to change the main drive, you'll have to remove the old one and install the new drive in its place. Ensure that all cables are securely connected and that the drive is properly seated in the drive bay. Then your computer should boot from the new drive successfully.

Why Need to Change Primary Hard Drive on Windows 10/11?

Before we delve into the intricate details of how to change your primary hard drive on Windows 10, let's first explore why you might want to undertake such a venture. The reasons can be manifold.

Perhaps your existing hard drive is running out of space, causing your system to slow down. It could be that you've invested in a high-speed SSD for improved performance and want to make it your primary drive. Whatever the case, understanding the need for this change sets the stage for a successful transition.

Common Challenges and Solutions

As with any technical undertaking, challenges may arise. Here are a few common issues users might face during the process and their solutions:
