In reply to YoWhadup:Yeah, it is a tad annoying an ISO for 64-bit 20H2, created using the Media Creation Tool, comes to around 4.7GB in size - too-big for a single-layer DVD.You could try a workaround of (1) downloading the regular ISO (which has 'install.wim', not 'install.esd'), (2) extract the specific SKU install-image you want from it (using something like DISM or GImageX) and (3) re-compress the new.
