    A iso file is like a zip. Many files and folders on a single file.
    You don't boot from a iso file.
    - You can burn a DVD using a win 7 iso file. It will boot as Legacy or UEFI.
    - To make a Win 7 USB boot able drive:

    Open a CMD window as administrator and type:

    diskpart
    list disk (it will list all drives. Identify the USB drive number)
    select disk n (replace n by the USB drive number obtained with list disk)
    clean
    convert mbr
    create part primary
    select part 1
    format fs=fat32 quick
    assign
    active
    exit (to exit diskpart)

    If you have a Win 7 installation iso file
    On Win 7 use 7Zip to extract all files and folders from the Win 7 iso file to the USB drive.
    On Win 10, mount the iso file and copy all files and folders to the USB drive.

    If you have a Win 7 installation DVD
    On another computer that has ODD, copy all files and folders from the DVD to the USB drive

    To make it UEFI boot able you must add the \efi\boot folder


    To make it universal (all Win 7 versions), go to \sources on the USB drive and delete \sources\ei.cfg.

    To install as UEFI
    Reset BIOS or load defaults.
    Set Disk mode to AHCI, not RAID
    Select OS mode = CSM or Select OS mode = other + UEFI (depends on BIOS).
    Disable fast boot and secure boot

    Windows can be installed in two ways: Legacy-MBR or UEFI-GPT
    To install as Legacy-MBR you must boot the installation drive as Legacy
    To install as UEFI-GPT you must boot the installation drive as UEFI.

    If you have a UEFI BIOS, you should install as UEFI-GPT
    Detach any other drives (SATA or Power cable) from the MB.

    During POST, press F12(?) to launch the boot menu. You will see two options for the USB drive. USB UEFI (Name) and USB (Name). Select USB UEFI (Name).
    Go to install and delete ALL partitions on the main drive till you have one and only one unallocated space and then proceed.
