Why need to migrate Windows 7 from HDD to SSD?

Migrate OS

Nowadays, many Windows users would like to transfer the OS from HDD to SSD. That’s mainly because the SSD is faster and more reliable than an HDD. Replacing the HDD with a SSD should be the most cost-effective way to give your computer a fresh start and give you a smoother experience.

How to migrate Windows 7 to SSD free without reinstalling

Moving or transferring Windows 7 from HDD to SSD is quite different from copying personal data (videos, pictures, images, documents, etc). It is a little complex, but a proper OS migration tool can make it easy. Here we would like to recommend you using the free partition manager: AOMEI Partition Assistant Standard. Its “Migrate OS to SSD Wizard” is designed to let you migrate Windows 7, Windows 8, Windows 10, Windows 11 to SSD in a stepwise manner that anyone can implement easily.

★Prior to OS migration, please do:
Connect the SSD to the Windows 7 computer via a proper method and make sure it is organized successfully by the PC.
Move some big programs from system drive to another one and shrink the Windows 7 partition to make it smaller if you want to migrate Windows 7 to a smaller SSD drive.
Back up everything important on the SSD drive since they will be erased during the migration process.

Now, download the software to see how to migrate Windows 7 to SSD step by step.

Further tips: Migrate Windows 7 to SSD without third-party software

If you don’t want to finish the migration by using any third-party software, then you try the Windows 7 itself “backup & restore” function. It allows you to make a system image backup and restore it to the SSD drive. However, only volumes formatted with NTFS can be protected. If the partition that you want to backup or set up as a backup destination drive is formatted with FAT32, you can convert FAT32 to NTFS without data loss. Following are detailed steps of creating a system image, creating bootable media and restoring the system image.

The restoring operation would overwrite the selected partition. Backup files to safe places like external hard drive or cloud storage.

▶ Part 1. Create a system backup image

Step 1. Click Start, choose Control Panel. In Control Panel, select System and Security.

Step 5. You can check the backup location and the size of the backup image. Confirm the settings via clicking Start backup.


Step 6. The image files are saved in “WindowsImageBackup” menu on the SSD.

▶ Part 2. Create a bootable media

Step 1. Download and install Windows 7 USB/DVD Download Tool.
