    Windows 3.1 > Windows 10

    Or you could just > while on the INSTALL screen
    press SHIFT + F10 and bring up a Command Prompt
    Type> Diskpart
    Type> Select disk 0
    Type> Clean

    Close command prompt and continue with installation

    This will also clear your HDD

    Windows 8

    THanks mysery126. I continue to have to boot into legacy mode. I will read into what you were saying more, because I do not completely follow. I am also trying to get my computer to work on "Intel Rapid Start Technology" mode in my sata bios setup. Any clue on how this works? Do I have to reintall my OS on a RAID volume to get that to work (I am throwing out various acronyms I do not fully understand just based on my recent troubleshooting research)? Any help is appreciated. Thanks again

    how do I tell what the partition scheme on my current disk is?

    Also, my SSD shows up in device manager, but not in disk management. Why is that?

    How to determine if a hard drive is configured with the MBR or GPT partition table (see screenshots below).

    Quote from this post: UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style). -> link

    Note: If you want to delete the MBR/GPT partition table entry, you must delete all the partitions until you only see Drive 0 Unallocated Space (see screenshot below). On the Where do you want to install Windows? screen, select a partition and click on the "Delete" option for each partition.

    - Once you have deleted all of the partitions, click on the "Next" button. The installation of Windows will begin. All the required partitions are created automatically during the install.
    - Or, if you know what you're doing, you can click on the "New" button and create a separate data partition.

    Normally, you should be able to delete all the partitions on the Where do you want to install Windows? screen.

    Note: But if you cannot delete all the partitions on the Where do you want to install Windows? screen.

    - Boot the computer using the Windows 7/8/10 installation media.
    - On the first screen, press SHIFT+F10 to bring up the command prompt.
    - Run the following commands at the command prompt.

    list disk (this will give you a listing of the disks on your system)
    select disk # (select the disk you want to clean, for example select disk 0)
    clean (running the clean command will delete all partitions on the disk)

    Even if you are going to use the GPT (GUID Partition Table), you do not need to run the convert gpt command, since you are not creating the partitions at a command prompt.

    - Close the command prompt window and continue your Windows installation as usual.

    Another way: Open Disk Management, click on View, then Top then Disk List.
