How to Set A Password to Computer Hard Drive
If your computer and hard drive support hard drive password, I recommend you set a password to your hard drive to keep others away from your computer. It is a better way than Windows login password to protect your computer from hacking. Windows password can be reset or recover easily, see Windows 10 Forgot Login Password Reset without Disk or Microsoft account.
Tips: If your computer and hard drive don't support hard drive password, you can use Bitlocker to encrypt data on your computer, see How to Set a Bitlocker Password to Hard Drive.
