Hello there ! I use Windows 7 on a 1tb western digital drive . I installed Windows 10 on a usb stick . Booted from it and saw my 1tb drive . Now I want to install a clean copy . I try to format it and I get a error: 0x8004242d . But I can't even still download windows on the drive . I tried a different hard drive . Was able to format junk on it but couldn't install Windows on it ! If someone can answer this question , then your a expert . Thank you . I've tried everything
