Hi all.
I appreciate the responses with lots of work around advice or using a USB drive, which I already know is an option.
But my point was rather that the MS website link to burn A DVD in English for me, in x64 ( cause all my jobs require 64 bit OS W10 Eng ) does not advise me that the file size I just downloaded will not fit on any std 1 dvd, does not set up the process to burn 2 disks, and is only useful to be mounted and then run from the existing hard drive - that needs to be wiped.
My EXPECTATIONS are not possible here on sp20H2.
That is my whole point.
Solution. Next service pak should be such as will fit on 1 dvd or be set up for burning disk 1 & 2.
Is this really too hard to do in a time when we are flying drones on Mars.
