Can I clone my C drive to SSD without boot failure?

“I'm preparing to upgrade my computer from an HDD to an SSD, so I'm looking for a safe clone tool. Are there any tools out there to clone C drive to a new SSD? I don’t want to reinstall my OS. The computer in question has Windows 10 Home.”

Why do we clone C drive to SSD?

SSD is more and more prevail because of its faster read and write speed, larger storage capacity, and lower hard drive power consumption. For a better computer experience, many users would like to set an SSD as the boot disk. Therefore, moving the current OS and transfer installed programs to SSD to avoid reinstalling becomes a nice choice for PC tech fanciers.

Besides this, if your PC boots slowly, the PC freezes during gaming, C drive has insufficient space, you can try to clone the C drive to a larger SSD for faster speed on the computer.

Before we start to see details about how to clone boot partition to SSD, you have something to prepare:

1. SSD: The SSD you prepared may have a small capacity than your HDD. It’s ok. As long as it’s larger than the used space of C drive is enough.
2. Windows computer.
3. Professional clone software: The reason you might need to select a reliable tool is to ensure the transferred OS can successfully boot as before and the steps should be easy. And don’t forget partition alignment after cloning, otherwise, your SSD might boot slow.
