    The DVD Media you purchased should have both. I think you are making reference to what to do if you don't have the DVD Media.

    See the instruction for a straight Windows 7 installation:
    UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Help Forums

    This might make it a bit more clear.

    Can you make a quote.
    The link in quotes above.
    Below is copy paste from the link.

    4) Boot from your UEFI 64-bit Windows 7 DVD or USB using the one time boot menu.

    Note
    If you do not have a UEFI 64-bit Windows 7 DVD or USB, then you can create a UEFI USB using the tutorial below.

    It leaves an opinion like there is no other way to go but one has to boot from UEFI boot media.
    (If a correct statement, then my Lenovo is excluded, because it appeared still to support Legacy boot)
