Instalar um Bootloader

Estas instruções de instalação the mostra como usar o GRUB para o boot utilizando BIOS (moda antiga) ou UEFI (moderno). Como no boot-update-1.7.2, agora no Portage, os passos são muito similares.

Primeiro, emerge boot-update. Isso também causará que o grub-2 e o efibootmgr sejam emergidos (merged), desde que eles são dependências:

(chroot) # emerge boot-update

Depois, edite /etc/boot.conf utilizando nano e especifique "Funtoo Linux genkernel" como a configuração default no topo do arquivo, substituindo "Funtoo Linux".

/etc/boot.conf deve agora parecer como isso:

boot {
	generate grub
	default "Funtoo Linux genkernel" 
	timeout 3 
}

"Funtoo Linux" {
	kernel bzImage[-v]
}

"Funtoo Linux genkernel" {
	kernel kernel[-v]
	initrd initramfs[-v]
	params += real_root=auto 
} 

"Funtoo Linux better-initramfs" {
	kernel vmlinuz[-v]
	initrd /initramfs.cpio.gz
}

If you are booting a custom or non-default kernel, please read man boot.conf for information on the various options available to you.

Old School (BIOS) MBR

When using "old school" BIOS booting, run the following command to install GRUB to your MBR, and generate the /boot/grub/grub.cfg configuration file that GRUB will use for booting:

(chroot) # grub-install --target=i386-pc --no-floppy /dev/sda
(chroot) # boot-update

New School (UEFI) Boot Entry

If you're using "new school" UEFI booting, one run of the following sets of commands, depending on whether you are installing a 64-bit or 32-bit system. This will add GRUB as a UEFI boot entry.

For x86-64bit systems:

(chroot) # grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id="Funtoo Linux [GRUB]" --recheck /dev/sda
(chroot) # boot-update

For x86-32bit systems:

(chroot) # grub-install --target=i386-efi --efi-directory=/boot --bootloader-id="Funtoo Linux [GRUB]" --recheck /dev/sda
(chroot) # boot-update

First Boot, and in the future...

OK -- you are ready to boot!

You only need to run grub-install when you first install Funtoo Linux, but you need to re-run boot-update every time you modify your /etc/boot.conf file or add new kernels to your system. This will regenerate /boot/grub/grub.cfg so that you will have new kernels available in your GRUB boot menu, the next time you reboot.
