THANK YOU.
My only problem was that Debian seems to read "findiso" parameter
instead of "iso-scan/filename" as Ubuntu does.
Now I boot Live .ISOs from GRUB2: Debian 7, Debian 8 and Debian 9.
Debian 6 not. After a minute says:
"
BOOT FAILED!
(...)
live-boot will not start a shell. The error message was:
Unable to find a medium containing a live file system
"
I've tried also with debian-8.10.0-i386-lxde-CD-1.iso (not Live: only
installer) but DebianInstaller says "No common CD-ROM drive was
detected" and asks for loading CD-ROM drivers or select CD-ROM module
and device (noone is accepted).
