With AOMEI Partition Assistant, you can easily migrate Windows OS drive only to SSD from HDD while keeping files and software on HDD. In this way, you can move only OS to SSD without reinstalling.
Generally, there are two main reasons to explain why people want to move only OS to SSD from HDD or another SSD. First of all, the improvement of the operating system is good enough for him or her. Maybe he or she just wants to keep OS separately running with other installed software. This group of the user who uses SSD for OS only normally has fewer requirements for PC configuration and doesn’t install large-sized games there.
The other one mostly comes from the objective factor, the limitation of SSD size. Even though SSDs come with larger capacity and more affordable prices, it is still far away from the needs of people’s daily use, especially the one who installed large software in particular. Therefore, to migrate OS to SSD from HDD while keeping files on HDD is an inevitable decision they have to make.
Traditional tools in Windows may disappoint its users in this field. If you insist on using Windows internal tools to move OS to SSD, try backing up system (create a system image) and then restoring the image on SSD. Remove HDD to test if it works fine and then format the previous system partition under Windows PE mode. You may think about third-party cloning software as well. As a matter of fact, the success of this migration depends on the system state on your hard drive. Most of them offer the disk clone function, which moves everything from one disk to another. This is no different from backing up the disk and restoring the image.
Fortunately, some professional partition managers like AOMEI Partition Assistant Professional can help migrate OS to SSD from HDD while keeping files on HDD. It allows you to resize the system partition on the SSD before migration, which would be very useful if you have other plans for the SSD. Considering that the destination disk is an SSD, this software will automatically align system partition to fully optimize the SSD drive performance. More importantly, AOMEI Partition Assistant ensures a successful boot from the target disk SSD. So, it is really worth trying.

Third, change the system partition size to your desire value.
Fourth, pay attention to the Note here. It may be useful later.
Fifth, confirm the virtual result. If everything’s fine, click Apply to execute it.
Note: This migration will move the entire C drive to SSD. However, the personal files you created on other partitions like E drive will not be moved and stay on the HDD. To boot computer from the destination disk, you have to enter BIOS to change the boot order.
