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
grub-install script. That script will translate the Linux device node such as
/dev/sda into a Grub device such as
(hd1). 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 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.
