Hi Matteo ! I follow your links and see a note about msi motherboards (mine).
archwiki suggested two commands : # mv esp/EFI/grub esp/EFI/BOOT # mv esp/EFI/BOOT/grubx64.efi esp/EFI/BOOT/BOOTX64.EFI I applied them and now the computer accepts to bott :-) I send this post from arch in my desktop. Many, many thanks Matteo. -- Philippe
