Product key for Windows is a unique code used to activate or purchase the software.
You already have Windows installed. The video likely suggested activation for a reason, but you don’t need a product key if you already own the software. Just check your settings or contact support for more details.
You viewed a tutorial on HDD installation and noticed Windows requesting a product key. You're unsure why you lack one. After upgrading from Windows 7/8, you should have received a digital key. If you purchased a pre-assembled unit, the key might be stored in the BIOS—though it's possible you can't view it without specialized software. Even with software, Windows will activate automatically once connected to the internet, provided you haven't altered any hardware components such as the motherboard.
This feature applies only to older versions of Windows. When you reinstall Windows, you can bypass the product key part of the setup. The software will activate automatically once you're online, no matter if you've connected a digital key or not.
You're having trouble starting your Lenovo PC from USB, and you can't install Windows. Let's troubleshoot that together.
You're operating in UEFI mode, which requires the GPT + UEFI (Non CSM) setup when installing Windows 10 on a flash drive. Use Rufus with a Windows 10 ISO you can download directly from Microsoft's site—via an Android/iPhone app or a mobile browser emulator instead of the official Media Creation tool. Just keep the same page and avoid using Windows to open it. When the system boots, press F8 or F12 to enter the boot menu and choose your USB drive.
