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 Qiling Disk Master 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, Qiling Disk Master ensures a successful boot from the target disk SSD. So, it is really worth trying.
Now, you can download the demo version, check out the preliminary work, and start moving only OS to SSD while keeping files on HDD.
First of all, install the SSD on your PC. Then install and boot Qiling Disk Master. Click Migrate OS in the left pane.
Second, select an unallocated space on SSD and then click Next. If there is no unallocated space on the SSD, you can check "I want to delete all partitions on disk 2 to migrate system to the disk (all data on SSD will be erased)" and then click Next.
Third, change the system partition size to your desire value.
Fourth, confirm the virtual result. If everything’s fine, click Proceed to execute it.
Fifth, pay attention to the Note here. It may be useful later.
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.
How do you migrate OS to SSD from HDD while keeping files on HDD? Obviously, Qiling Disk Master answers this question quite well. Easy steps and graphical interface, there is no excuse for denying such a helpful migrating tool. Speaking of helpful, you can use it to create bootable Windows to go USB drive, make Sandisk USB bootable, for example. It can be used to resize partitions and merge partitions, so it will be handy when you want to extend system drive into non-contiguous space. The conversion between GPT and MBR, NTFS and FAT32, logical and primary without data loss are available, too.
