Ubuntu 12.04 + RAID0 + o Windows 7 não está carregando

Question

Eu tenho um PC com 2 Hd (1Tb cada) no RAID0. Eu tinha um Windows 7 de 64 bits trabalhando por vários meses.

Quando instalei o Windows, deixei uma partição de 100 GB vazia para instalar o Ubuntu algum dia.

Eu estava usando o Linux no Virtualbox, mas esta semana tentei instalar o Ubuntu 12.04 nesta partição de 100 GB.

Eu usei o cd alternativo do Ubuntu, porque o cd 'normal' estava me dando problemas com o RAID0. A instalação do GRUB sempre relatou um erro. Depois de muito trabalho, descobri que precisava instalar o grub na partição /dev/mapper/isw_chjbfeec_DougRaid1 (veja Bootinfo abaixo).

A instalação do Windows criou uma partição de inicialização de 100Mb, então eu precisei instalar o grub nesta partição.

Agora eu tenho o Ubuntu funcionando 100% OK.

O problema é que o Windows não está inicializando! A opção windows está presente no menu grub, mas quando eu escolho a opção Windows, há uma tela preta e depois disso o menu grub reaparece.

Como podemos ver a parte do Windows no grub:

menuentry "Windows 7 (loader) (on /dev/mapper/isw_chjbfeec_DougRaid1)" --class windows --class os {
        insmod part_msdos
        insmod ntfs
        set root='(sda,msdos1)'
        search --no-floppy --fs-uuid --set=root C89C73D19C73B910
        chainloader +1
    }

Eu tentei muitas combinações na linha:

set root='(sda,msdos1)'

mas sem sucesso

Eu tentei alterar o UUID para o /dev/mapper/isw_chjbfeec_DougRaid2 UUID, mas o GRUB relata um erro.

O que devo fazer?

    

Answer 1

Existe um problema com a sua máquina em que o GRUB está instalado no seu MBR, substituindo a instalação padrão do Windows. Se é só isso que você quer que o seu sistema operacional Windows para iniciar, então você pode simplesmente ir para reparar o MBR. Você pode usar o seu disco do Windows para entrar no modo de recuperação e, em seguida, seguir o procedimento abaixo para reparar seu MBR e inicialização.

STEP1: Goto windows recovery mode and open up the command prompt there
STEP2: write the following code to accomplish your target:
        x:\sources>bootrec /fixmbr
        x:\sources>bootrec /fixboot
STEP3: Just restart the computer after that and you will loose the GRUB loader and will directly be booted into windows. 

Agora você precisa reinstalar o grub para fazer seu ubuntu funcionar novamente. Se você tiver alguma dúvida sobre a reinstalação do grub, deixe-me saber nos comentários. Vou editar a resposta com detalhes para ela.

    

Answer 2

A inicialização dupla com a partição de sistema do Windows nunca funcionou para mim e estou acostumado a fazer isso de maneira diferente, mas enquanto os sistemas baseados em UEFI continuam substituindo os sistemas baseados em BIOS, vamos tentar corrigir isso.

Existe uma página wiki em que fixa a inicialização dupla para sistemas baseados em UEFI na documentação do Ubuntu Community. Mas você provavelmente não tem bootmgfw.efi desde que você está usando uma tabela de partição do MS DOS, então isso não funcionará. De acordo com o Wikipedia , o Windows deseja carregar bootmgr primeiro, que deve estar localizado na raiz da partição de sistema do Windows. / p>

Então monte a partição no Ubuntu e faça o seguinte:

grub-probe --target=fs_uuid /path/to/windows_system_patition/bootmgr

Isso deve retornar o UUID da partição de sistema do Windows. Agora modifique sua entrada de menu do Grub 2 para Windows assim:

menuentry "Windows 7 (loader) (on /dev/mapper/isw_chjbfeec_DougRaid1)" --class windows --class os {
        insmod part_msdos
        insmod fat
        insmod ntfs
        set root='(sda,msdos1)'
        search --no-floppy --fs-uuid --set=root UUID_of_Windows_System_Partition
        chainloader (${root})/bootmgr
    }

Substitua UUID_of_Windows_System_Partition pelo UUID que você obteve do comando anterior. Observe que adicionei insmod fat , porque essa partição costumava ser uma partição FAT e o destino do chainloader é o Gerenciador de inicialização do Windows. Também posso ver um w7ldr ao lado de bootmgr em minha VM do Windows 7, que deve ser o Bootloader do Windows 7. Faça uma cópia da entrada de menu acima e substitua bootmgr por w7ldr e tente também. Não se esqueça de executar sudo update-grub depois de fazer as edições, mas você provavelmente sabe disso. : -)

Espero que isso funcione, desejo-lhe boa sorte.
