When a Windows 10 device (laptop or PC) is protected with the BitLocker, then the only way to access its contents or to reset the device (by using the "Reset This PC", "Refresh your PC" features), or to reinstall Windows, is to unlock the operating system drive C: by using the BitLocker Recovery Key or the BitLocker password.
