How do I migrate Windows 10 to a new HDD/SSD without cloning?


My two computers are with their own Microsoft account and run Windows 10 Home 64-bit. Now, I'd like to change my disks on these two PCs, one would be to simply replace the present HDD with another 1TB HDD, while the other would be to upgrade to a 2TB SSD with a GPT scheme. I don't want to clone the whole disks, how do I move just my OS to my SSD?

Assume you installed Windows 10 on an HDD and wish to boot your machine from an SSD or a larger HDD. The most common method is to make a clean installation. However, a new OS installation is time-consuming and inconvenient since you must reinstall apps and data kept on the C drive.

There is a method to move the previously installed Windows OS to SSD without reinstalling or cloning if you want to maintain all current data on the system drive. You have the option of moving Windows from HDD to SSD or another HDD.

The thing is if you want to do a foolproof OS migration, a professional moving tool is necessary. Since your PC needs not only a C drive to boot but for some other hidden files, it’s quite difficult to move OS manually.

Here, we recommend you AOMEI Partition Assistant Professional to make an easy and safe OS migration. The “Migrate OS to SSD” feature can migrate all data in the Windows installation files and folders, boot files, and configurations from your computer to a new drive.
