    It may be possible to troubleshoot and fix the boot problems and operating system/registry problems.
    Sometimes access denied can be fixed.
    Sometimes missing dll files can be fixed.

    If you clean install, it can be performed in the shortest time however the files will be cleaned.
    If you boot rescue the files can be backed up to another drive.

    If you troubleshoot these are the initial steps.
    The next steps will be based on the results displayed from these commands.

    Perform the following steps:

    1) Find a flash drive that you can format: ( > or = 8 GB)
    2) Create a bootable Windows 10 iso (now Windows 10 build 1803)
    Download Windows 10
    3) Insert the bootable Windows 10 iso flash drive into any USB port
    4) Power on the computer and click the applicable keyboard key or modify the BIOS boot order so that the USB external HD is on top
    List of PC brands with their corresponding hot-keys
    5) It may take 5 - 10 minutes for the iso to load while viewing the Microsoft Windows icon
    6) Select the language, time, currency, and keyboard, or click next
    7) Click troubleshoot
    8) Click command prompt > Administrator: X:\Windows\System32.cmd.exe > X:\Sources>
    Type all of these commands.
    Comments are in parenthesis.

    If the drive you are trying to install on is the Windows drive with 4 partitions. You need to delete them all and then click on the unallocated space to install Windows 10.
