    There is the legacy BIOS (no UEFI at all), needs to boot from MBR disk. Data disk(s) can be GPT.

    Next, the Gen1 EFI, that proprietary type is almost extinct.

    Third, Gen2 UEFI, now common in PCs. It includes a CSM and legacy BIOS INT10 emulation. Can boot Windows 7 in EFI mode, like Gen1.

    Next round of UEFI, Gen3 (mostly found in newer Notebooks and Laptops) lacks the CSM and BIOS INT10 emulation, completely. It drops the Windows 7 compatibility. That's the type of UEFI discussed about, here.

    Please excuse my ignorance. Not even possible to sacrifice UEFI completely to go with pure legacy only! ( Gen 3 UEFI )

    Thanks. ...

    Unfortunately there is no settings for legacy boot in BIOS - only UEFI boot mode... :(

    that's annoying especially if you want to install win7 on that machine but i heard and i read that installing win7 on pure uefi (without CSM and legacy BIOS) is now possible subject certain conditions which one of them is to disable boot logo.

    No. You have to use Windows 10 bootloader and disable legacy VGA drivers (and pre-integrate vendor specific graphics drivers to Windows 7 ISO).
    Boot logo Works.

    indeed, you're right.
    Using windows 8.1 bootloader is also an alternative.

    that is assuming the vendor specific graphics drivers can actually support Win7

    otherwise better to run Win7 thru VMWare
