Bem, vamos devagar, e sempre usando o LiveCD, ok?
Primeiro vamos montar a partição do Linux para poder começar alterando o
menu.lstAbra uma seção do terminal/Consola (Aplicações > Acessórios > Terminal ou Consola).
Digite o comando abaixo para não termos que usar o
sudo o tempo todo.
sudo -sDepois tecle enter, afinal esta usando o LiveCD.
Agora vamos montar a tal partição:
mount /dev/sdb5 /mntFaçamos um backup do
menu.lst:
cp /mnt/boot/grub/menu.lst /mnt/boot/grub/menu.lst.bkp.2008.06.06Agora edite o arquivo:
gedit /mnt/boot/grub/menu.lstSubstitua as informação alteradas no arquivo (elas estão em negrito):
# menu.lst - See: grub(Legal, info grub, update-grub(Legal
# grub-install(Legal, grub-floppy(Legal,
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.
## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default 1
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 10
## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu
# Pretty colours
#color cyan/blue white/blue
## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line) and entries protected by the
# command 'lock'
# e.g. password topsecret
# password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
# password topsecret

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below
## DO NOT UNCOMMENT THEM, Just edit them to your needs
## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=e14e2ece-949b-4ef7-bee0-4ceff9975939 ro
## Setup crashdump menu entries
## e.g. crashdump=1
# crashdump=0
## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd1,4)
## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true
## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false
## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash locale=pt_BR
## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false
## Xen hypervisor options to use with the default Xen boot option
# xenhopt=
## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0
## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single
## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all
## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true
## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false
## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false
## ## End Default Options ##

Feito isso salve o arquivo.
Execute o comando abaixo para sair da partição do sistema:
cd /Agora desmonte a partição:
umount /mntAgora vamos ver uma coisa (ainda vamos precisar daquele terminal aberto, não feche ele).
Abra o
gparted (ele deve ser aberto com direitos administrativos, então abra pelo terminal aberto):
gpartedSelecione o primeiro HD (
/dev/sda), clique na única partição que tem (/dev/sda1) usando o botão direito e na opção
Gerenciar Marcadores.
Feito isso desmarque a opção boot dela.
Execute novamente o comando abaixo e retorne aqui, para assim que estiver certo vamos reinstalar o GRUB.
sudo fdisk -lContinue usando o LiveCD, temos coisas ainda para fazer. Caso esteja tudo ok vamos reinstalar o GRUB. Quando reiniciar (vou falar agora, caso esqueça depois) verifique na BIOS se é o segundo HD que esta selecionado para o boot.
