How to clone Windows 10 HDD to SSD free without software?

First things first, make sure your SSD is installed properly. If it's a laptop, you might need to replace the HDD with the SSD; if it's a desktop, just plug it in. You can also use a USB-to-SATA adapter if you want to keep both drives connected at the same time.

Before we start cloning windows 10 HDD to SSD, back up any important files from your HDD. It's not often, but there's always a tiny risk that something might go wrong during cloning, and you don't want to lose important stuff. Trust me; I learned this the hard way when a friend's drive got corrupted!

There are several free tools you can use. I've had good luck with Macrium Reflect and EassUS Todo Backup Free. Both have user-friendly interfaces and do a great job at cloning. Just download and install one of these programs.
