possibility of transferring the system in a USB Hard Disk

[cofot28]

Huh.

I've been flashing uSD cards and USB thumbdrives from moOde/DietPi/Volumio/RPiOS/you-name-it disk images with Belena Etcher in Win10 and Linux Mint for several years with nary a problem. Worked first time, every time.

Well it seems that flashing is the easy part. Then it seems that pi needs also some kind of firmware update to boot from a usb (in my case an ssd with a sata-usb cable. Is it so? In any case when I put it directly even to my latest pi4 8gb nothing happens.

Sorry post deleted, just noticed you are running a pi 4.

Well now that you realise the issue I would ask you to read again my mail of 14 Oct and let me know your thoughts. Currently pi development reminds me the times of Windows 3.1. The only way for ordinary people to use it is if bright people in informatics makes these hardware usable for those ordinary people. Ordinary people cannot turn massively into information gurus. The paradigm of Steve Jobs shows the way.
