Even though spinning hard drives can store a ton of stuff and give you more bang for your buck in terms of gigabytes, they're pretty slow compared to solid-state drives (SSDs), especially if your HDD ...

Windows 10 will load as if you hadn't replaced the drive, so Macrium Reflect is still installed. Launch it and follow the same steps to clone your external drive to the new internal drive.

I would like to get links from you. Actually Macrium Reflect is the only one that works for free out of several popular ones I have tried. All failed to clone smaller disk to bigger disk.

In addition, make sure the drive you are cloning to has enough storage space to take all the cloned data. For instance, you wouldn't want to try and clone a 2TB HDD on to a 256GB SSD now would you?
