Isso pode ajudar. Você precisa manter pressionada a tecla SHIFT no teclado o tempo todo que o seu computador inicializa. Isso irá direto para a sua tela do GRUB se o grub estiver instalado corretamente.
Eu tenho tentado descobrir como resolver meu problema por quase 20+ horas, e ainda não consigo descobrir a solução. Se alguém tiver sugestões, por favor me diga! Também como um lado não, depois de mudar de sistema operacional para o sistema operacional algumas vezes, eu não estou voltando para o ambiente Linux para corrigir o problema até que eu tenha uma melhor compreensão do que estou lidando. Obrigado a vocês antecipadamente por me ajudarem a encontrar uma solução!
Depois de experimentar o Ubuntu 12.04 LTS, onde ele é instalado como um programa no Windows 7, decidi alocar algum espaço de driver para que o sistema operacional o instalasse em meu computador para que ele pudesse ser executado sozinho, e não no Windows 7 .
Antes de instalar o Ubuntu, aloquei espaço para o sistema operacional diminuindo o drive C: em 100 gb, que é onde eu irei instalar o Ubuntu.
Instalei o Ubuntu com a opção "Instalar junto com o Windows 7" selecionada sem problemas. Mas quando eu reiniciei o meu computador, ele carregou o Windows 7 imediatamente sem exibição do menu de inicialização. Eu reiniciei novamente e mais uma vez o menu não apareceu. Então eu imaginei que talvez eu tenha instalado incorretamente, então eu instalei de novo.
Quando instalei o Ubuntu, desta vez selecionei a última opção nas opções de instalação. Isso me levou a uma janela que mostra todas as opções / dev / sda de onde eu vou instalar o Ubuntu. Agora, a coisa que me confunde é que o espaço de 100 gb que eu aloquei é chamado de dev / sda5 ext 4. Havia uma opção de espaço livre, mas que tinha apenas 20 GB de tamanho. Como a opção 100gb / dev / sda5 ext 4 parece o local adequado para colocar o Ubuntu, é aqui que eu escolhi a instalação.
Após a instalação, eu reinicio o computador e, mais uma vez, ele inicializa o Windows 7 imediatamente, sem menu de inicialização, especificando qual SO eu posso selecionar.
Eu verifiquei sob gerenciamento de disco no windows e o espaço que eu aloquei para o Ubuntu em janelas ainda diz que 100 gb não foram alocados. Não deveria dizer outra coisa? Ou isso é normal ou fiz algo errado?
Qualquer conselho seria muito apreciado sobre como posso resolver este problema!
Abaixo, postarei os resultados do script de informações de inicialização:
