"You might note the absence of a device_path option (e.g.: /dev/sda) in the grub-install command. In fact any device_path provided will be ignored by the GRUB UEFI install script. Indeed, UEFI boot loaders do not use a MBR bootcode or partition boot sector at all." - https://wiki.archlinux.org/title/GRUB But a device_path is likely required by the OP, since legacy BIOS is used and ... it seems my guess is correct: "# grub-install --target=i386-pc /dev/sdX" - https://wiki.archlinux.org/title/GRUB#BIOS_systems
