I made it (with latest debian-gnome 9.3 live), and tested it OK on *another* machine. But on the machine where the problem is, it does *NOT* boot. It does display the key brand/model (instead of "Windows boot manager") but when selecting it, the punishment is as usual : black screen with cursor, game over. No grub message or output of any kind. ॐ -- Michel Bouissou <mic...@bouissou.net> OpenPGP ID 0xEB04D09C _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
