possibility of transferring the system in a USB Hard Disk

[cofot28]

perhaps @cofot28  believes that  install always happens from sd card ? and is unaware that the downloaded image can be written to sd-card or usb stick or ssd and the Pi booted from any of those for install and subsequent use.?

I must say, it's the first time I can recall that being said in such clear and unambiguous terms.  Are there any steps lurking in the "and the Pi booted from any of those" part.

There's nothing special about the moOde distribution image. It can be installed and run in all the ways the Raspberry Pi OS image can be and with all the same caveats. 

The possibility has been discussed before, cf, http://moodeaudio.org/forum/showthread.p...3#pid24673

It isn't obvious to me that moOde needs a built-in routine to effect this.

Needless to say that I tried through rufus  in Win10 and with Linux Mint corresponding tool and I miserably fail. I should also add that I have no intention to invest seriously in pi4 ecosystem. For my everyday work I have my pc which has at least 5 times more processing power and is much simpler for me to run. I came to the world of Pi only because of it's vertues in audio fidelity. If people like me are part of moode's target groups then my view is that more efforts are needed to simplifyi, providing options within the menus and system, and last but not least plain language manuals for ordinary melomans/audiophiles. Until then I will keep using my moode pi4 set up in association with foobar through uPnP and enjoy music.
