  • I would download the ISO again and recreate the USB image.

    Use the following instructions:

    The Windows 8 Developer Preview is delivered as an .iso image that must be converted into installation media stored on a DVD or a USB flash drive. On Windows 7, the easiest way to convert this file is to use Windows Disc Image Burner. On Windows XP and Windows Vista, a third-party program is required to convert an .iso file into installable media—and DVD burning software often includes this capability.

    Note: The .iso file that contains the developer tools requires a large capacity DVD called a DVD-9, as well as a DVD burner that can handle dual-layer (DL) DVDs. Most modern burners should be able to handle this format.

    Then check the Sha 1 Hash after the file has been downloaded.


    Let us know if this helps.

  • In addition to the information from Chris, I suggest you check the Sha 1 hash to be sure your download is correct.

  • No, but if the sha 1 hash is corrupt, the download could be missing files.

    If the download manager is working correctly, it will not corrupt the file.
     
    When the download is complete, the downloaded file must be byte-for-byte identical to the original. The purpose of the SHA-1 hash is to verify that this is the case. If it is not, then the download is damaged, and you cannot use it.
