Restart the operating system again.
Sure thing. It's definitely doable to turn off Windows from a failing hard drive and then bring it back online on the active drive. The situation you described sounds like a classic case of a corrupted or failing partition. You’d need to reinstall Windows using the new drive, which would restore the key. For help, you could reach out to Microsoft support or a tech forum.
If it doesn't work, just call the automated activation number they provide. It's super easy and if that fails, they'll send you a new key.
