    Gotcha. However, they are the same in the real environment. I guess he did in VM so he can take the screenshot.

    The schema is the same - but I'm trying to figure out what the physical disk looks like now.
    I'm not sure why I want to know that, because I also know that Windows creates the proper schema on a blank drive. Just curious I guess.

    I'm not certain there is an issue other than perhaps a misundertanding (post# 1)
    GPT Partition Style Probnlem for Clean Install of Windows 10

    Having upgrade Windows 8.1 to W10, I wish to now do a clean install, but cannot install over current installation due to
    it being a GPT Partition style boot. I have heard this can be deleted and replaced with MBR but then will I have to format the partition?
    Win10 can be installed on a GPT drive with UEFI.
    Win10 can be installed on a MBR drive without UEFI.

    If the firmware is UEFI, the disk needs to be GPT.
    If the firmware is BIOS, the disk needs to be MBR (maybe that's changed and BIOS can boot GPT drives)

    There need not be any real consideration about converting GPT to MBR.

    Correct with one addition. From boot menu, they must select the correct boot option.
    Another confusion is: Prior to EFI firmware 2.0. The USB installation media must be formatted with FAT32 for the firmware to recognize.

    Clean install completed! I was trying to install via Legacy mode, I had thought that you had to use this mode anytime you wanted to boot, but I found out installing Windows is different.
    Installation was as simple as installing on my Desktop which had conventional BIOS.
