说明
grub-install installs the GRUB bootloader to a disk device or EFI System Partition. The installation method differs between BIOS/legacy and UEFI systems. For BIOS systems, GRUB is installed to the Master Boot Record (MBR) or a BIOS Boot Partition on GPT disks. For UEFI systems, GRUB is installed to the EFI System Partition (ESP), and the --bootloader-id option sets the name shown in the UEFI boot menu. After installation, run grub-mkconfig to generate the configuration file.
