Bonjour.

Here is exactly what I did (i.e. nothing special)!



This is my Pi 500+ default boot order since the beginning.



This is the boot order I'ld like to use.



This is what "nano" is supposed to write.



But did it?




Nope! This where is the damned bug !!!





So, should I "chown" or "chmod" some file or directory to bypass the problem?

Any idea will be very appreciated.

TIA.
