Dear Patrice, Rog, Wiebe, and Jose, Many thanks for your help! Here is the summary of the outcome:
To boot a (Linux) USB key, one has to put in the "settings": "secure boot" and "Intel platform technology": disabled, and in "configuration": storage - controller mode: AHCI mode. The latter damages the windows partition, and there is a warning, when this change will be applied. Then, boot with F12 works, and 20.04 installation works fine on this machine. The windows partition is no longer bootable, and since I did not buy the media, I was unable to repair this partition (I do not really need windows; I wanted to make a dual boot system by curiosity). So, finally, I also recovered the windows space for Linux. ".ch" is Switzerland. Best regards, François

The USB key was prepared with dd and I checked on another Laptop that it is bootable. When I stop booting with F12 (S540), only the Windows boot device (Windows boot manager) shows up - the USB key is not seen. I played also with the BIOS (F2), but was unable to set it up in such a way that the USB key appears with F12. Could you please give me a hint how to boot the USB key. I would like to make a dual-boot system. Thanks a lot! Best regards, -- François P.
