Now, let's explore the process of how to clone OS to new SSD. Here are the steps:

Step 1. Open the software and navigate to the Clone tab. From there, choose System Clone.

Choose System Clone

Tip: If you wish to clone all the contents of the system disk, opt for "Disk Clone" instead. This functionality enables you to clone a hard drive to an SSD or clone an SSD to a larger SSD, among other possibilities.

Step 2. Next, choose the new SSD disk as the destination path and click "Next" to proceed. The program will automatically detect the source drives that require migration.

Tip: If the new SSD contains data, the program will display a warning that all partitions on the SSD will be deleted. Proceed only if you have already backed up important files.

Step 3. Take a look at the operation preview, which displays the OS drives that will be transferred to the SSD. It is highly recommended to enable "SSD Alignment" at the lower-left corner to enhance the write/read speed of your new SSD. Finally, click "Start Clone" to begin the process of migrating the OS to the SSD in Windows 10 or any other compatible system.
