Olá pessoas, eu tenho o Linux Ubuntu que comprei junto com o notebook, só que ele vem com UEFI, e instalar sistemas em modo texto (manual) e uma coisa horrivel, mais funciona o 64 Bits no Legacy, eu nunca testei.

O que que o UEFI e a instalação manual têm a ver?

No gentoo uefi da:

Em outro PC. Dell Inspiron 3421

PARTITION TABLE:

/dev/sda1 -> EFI
/dev/sda2 -> /boot
/dev/sda2 -> / - Fedora
/dev/sda3 -> swap
/dev/sda4 -> gentoo


$ grub-install --target=x64_86
grub-install: erro: disco 'hostdisk//dev/sda1' não encontrado.

no UBUNTU A MESMA COISA.

Estava, mais mesmo assim não funciona.

$ mount /dev/sda1 /boot/efi
fora do chroot.

pois dentro do chroot da:
$ mount /dev/sda1 /boot/efi
mount: permission danied.

Montagem de sistemas de arquivos requerem permissões de root '#', parece-me que você tentando como usuário normal '$'.
A linha de comando para EFI é um pouco diferente:

# grub-install --target=x86_64-efi --efi-directory=/boot/efi

Não, eu ja estava no root, mais mesmo assim, não monta, não instala.
Em modo Legacy, ele instala como uma beleza, mesmo em dualboot.
Esse e meu guia:

uso o Gentoo-LIVECD
commandos

$ sudo su
# gparted
# mount /dev/sda4 /mnt/gentoo
# mkdir /mnt/gentoo/boot/
# mkdir /mnt/gentoo/boot/efi
# cd /mnt/gentoo
# links http://gentoo.c3sl.ufpr.br/, navego ate os stages, faço o download.
# tar xvjpf stage3-*.tar.bz2 --xattrs --numeric-owner, mais com stage
Faço os links, copio o repositorio, o resolv.conf
# mount -t proc /proc /mnt/gentoo/proc
# mount --rbind /sys /mnt/gentoo/sys
# mount --rbind /dev /mnt/gentoo/dev
# chroot /mnt/gentoo /bin/bash
# source /etc/profile
# export PS1="(chroot) $PS1"
# emerge --sync
# eselect profile set 1
"""
Faço as configurações do handbook
"""
# genkernel all --makeopts=-j7
coloco no make.conf
GRUB_PLATFORMS="emu efi-32 efi-64 pc"
# emerge --ask grub
# grub-install --target=x64_86-efi --efi-directory=/boot/efi
ai da o erro.

Deixe eu ver se eu entendi...... Você quer desabilitar o uefi no seu pc?
Se for isso: acesse a bios, desabilite o modo uefi e habilite o legacy mode.
