I used the following parameters : boot=live config noswap nopersistent noeject nosplash locales=fr_FR.UTF-8 keyboard-layouts=fr keyboard-variants=oss live-config.username=root vga=791 I also tried with those ones : boot=live config noeject locales=fr_FR.UTF-8 keyboard-layouts=fr keyboard-layout=fr vga=791 with the same result, still in qwerty. Thanks again
