I'm replacing my current hard drive with a new SSD and want Windows to boot from the SSD. I'm unsure whether I should perform a clean Windows installation or clone the old drive. My HDD contains junk, but also important documents, photos, and possibly drivers, so I don't want to lose anything. Cloning seems convenient, but I'm worried it will copy everything—including files I don't need—and fill the SSD. I'm also confused about Windows ISO files, bootable USB drives, and what the "Reset this PC" option actually does. What's the safest step-by-step process for installing Windows on the SSD, keeping my important files, and eventually using the old HDD for storage?

“Reset this PC” reinstalls Windows on the current system and gives you options to keep or remove personal files. It isn’t the same as moving Windows to a new SSD, and it won’t automatically organize the old drive for you. For a completely fresh setup on the new drive, use installation media instead. Afterward, set the SSD as the first boot device in the firmware settings if the computer doesn’t select it automatically.
The safest approach is to back up your important documents and photos first, then install Windows fresh on the SSD. You don’t have to delete anything from the old HDD. Create a Windows installation USB with Microsoft’s Media Creation Tool, shut down the computer, disconnect the old drive temporarily, and install Windows to the SSD. After Windows and the necessary motherboard and graphics drivers are installed, reconnect the HDD and copy over the files you actually want. Keep the old drive untouched until you’re certain everything important has been transferred; afterward, you can format it and use it for extra storage if you want.
Using a blank USB drive is the simplest and safest method. An 8 GB or larger drive is usually enough, and the Media Creation Tool prepares it for you. Disconnecting the old drive during installation also helps prevent accidentally choosing the wrong disk.
Do I definitely need a USB drive for a fresh installation?
