What You’ll Need Before Installation

Before you begin installing Windows 10, make sure you have everything ready.

✅ Required Items:

• A new or empty hard drive (HDD or SSD)

• A second computer to create the installation media

• A USB flash drive (8 GB or larger) or DVD

• Windows 10 installation media (created using Microsoft’s Media Creation Tool)

• A valid Windows 10 license key (optional if previously linked to your Microsoft account)

• Stable internet connection (for updates and activation)

💡 Tip:

If your new hard drive replaces an old one, back up any important files first. You’ll need to perform a clean installation, which wipes all data from the new drive.
