The answer is yes. When installing an SSD on a laptop, you are suggested to replace the computer's hard drive and reinstall the operating system in some forums. But the whole process is somewhat time-consuming and painful.

  • It requires a Windows bootable USB drive or installation disk to install Windows.
  • The process will be done in a Windows recovery environment, unfamiliar to most computer users.
  • The process will delete files and applications that don't come along with the preinstalled operating system. Thus, it would be best to back up files to an external drive before reinstalling for data security.
  • After Windows installation, you have to set up your preferences and install the programs you want to use.

So complicated! Isn't it? Is there an easier way to install an SSD on a laptop without having to reinstall Windows?

Yes, you can clone your laptop's hard drive to an SSD on your Windows computer. And everything, including the operating system, installed programs, files, preset settings, etc., is kept in the new SSD as it was in the old disk. To this end, all you need is third-party disk cloning software. But which cloning software can you use to clone your HDD to SSD?
