how to install windows on a new hard drive without disk

Inactive profile

Hi,

A product key is a 25-character code that's used to activate Windows. In most cases, Windows 10 activates automatically using a digital license and doesn't require you to enter a product key.

To resolve your concern about reinstalling Windows 10 on a new hard drive, follow the steps provided on the article Reactivating Windows 10 after a hardware change. You can also check Andre Da Costa's response on this link for more options about your concern.

Let us know how it goes.

If Windows 10 was previously activated on the laptop then you don't need a key, activation will be automatic once connected to the internet.

You do need to be sure that you install the same edition of Windows 10 as was activated previously.

You can use the Media Creation Tool to create boot USB/DVD media.

You can use this on another PC to create the boot media. Just select the option Create installation media for another PC.

Windows 10 Digital License

When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft Activation Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate. You will prompted to enter a product key a couple times through the installation, click I don't have a key and Do this later.

There is no need to know or get a new key, but if you have issues with Digital Licensing or the Activation Troubleshooter, you can utilize an existing Windows 7 or Windows 8/8.1 product key you already own to reactivate if necessary. or use the reset function in Windows 10.
