Setting up Windows 8 on an SSD after installing it on a previous Windows 7 installation on an HDD
You're planning to upgrade to Windows 8.1 and add an SSD while replacing your existing HDD. Since you already have a prebuilt system with Windows 7, you'll need to remove Windows 7 before installing the new OS. There are guides available that walk you through uninstalling Windows 7 step by step. Once done, you can proceed with installing Windows 8.1 and setting up the SSD.
Get a .iso file from Windows 8 and create a bootable USB drive from it.
