Not sure if I understood everything. I created the USB bootstick with the latest 5yr "warranty" versión.
Then, I reebooted and selected the 1st option: start or install.
I then selected boot from USB.
Then I got the BIOS Error screen for some second.
After that, the yellow screen from the UEL below, but with white instead of green.
I have succeeded in using your "SGX to "enable" pretty quickly.

Thank you very much for your help and your kind words in particular.
I might try again later on, but for now, I need to get my PC moving again.
Strange that it did not work out with the old ASUS laptop either.
I will bookmark this post to be able to get back to it.
Funny enough, creating the Win10 bootstick was a piece of cake (as well) and the installation went smoothly (apart from the "1 m." updates and restarts).
Strange, with the...
