Donc dans Emulation Station, il faut absolument faire Eteindre (via Start ou Select pour aller plus vite) pour que ça sauvegarde tes paramètres avant de débrancher!
@substring It's ok now. As you said, I've redownload the .img file and install it with Etcher and it works.
I think the problem is that when the installation with Etcher is done, Windows ask the user to format SD Card because he can't recognize the new file system. If the user don't take care, he can reformat the SD card.
