Grub is the [[bootloader]] most people will use with Funtoo. Grub is very powerful supporting multiple partition types, filesystems, and operating systems through a modular framework. Grub will generally be installed through the <code>[[grub-install]]</code> script. That script will translate the Linux device node such as <code>/dev/sda</code> into a Grub device such as <code>(hd1)</code>. This has to be done because Grub will only know about devices that your system's firmware knows about. It generates a core Grub image with enough support to read the [[The_Root_Filesystem#.2Fboot_:_Static_files_of_the_boot_loader|boot]] partition. It modifies the Grub [[boot image]] so that it can find the core image and installs the boot image to the master boot record.
