Clone laptop HDD to SSD guide 1: How to clone Windows 10 hard drive to a smaller SSD using DiskGenius Free edition?
This guide applies to clone a laptop internal hard drive where Windows 10 is installed to a smaller SSD. After the disk cloning process completes, the laptop will be able to boot from the new SSD directly, and thus you can install the SSD properly in advance. If you do not want to migrate Windows system to new SSD, you can just clone disk following steps in guide 2.

Before cloning Windows 10 to SSD, you may need to do a little preparation works on current hard disk, for example, clean up the drive and remove data that you don't want to move to your SSD. To do this, you can delete useless files, uninstall unnecessary programs or use third-party software like CCleaner to free up disk space.
Step 1 Install and launch DiskGenius Free edition from your computer. Then choose Tools > System Migration, as the picture below:
Step 2 Select destination disk and click OK button.
The pop-up window lists all connected disks except for the system disk, and you should choose the correct disk from the list.
Step 3 Configure system migration process.
