Como remover entradas desnecessárias do EFI do GRUB?

Question

Como posso me livrar dessas entradas de menu indesejadas do GRUB. Meu Ubuntu e Windows está sendo carregado corretamente, mas essas entradas desnecessárias eu não preciso disso. Desde já, obrigado. É assim que o grub.cfg (/boot/grub/grub.cfg) se parece no meu caso:

Answer 1

finalmente eu sou capaz de resolver este problema ... passei por cada arquivo no diretório /etc/grub.d/ e me livrei das entradas não necessárias e então rodei 'sudo update-grub'. Entrei no 25_custom e limpei todas as entradas nas quais não eram necessárias (para inicializar na hora da inicialização - como todas as entradas desnecessárias da EFI).

sudo gedit  /etc/grub.d/25_custom
sudo update-grub

Por favor, certifique-se de fazer um backup dos arquivos que você está editando. Certifique-se de que você não está armazenando nenhum dos arquivos de backup começando com 25_custom ... se você armazená-lo com a data de 25_custom_today etc .... O carregador de inicialização da EFI ainda lerá as entradas ... Para pessoas que têm HP Laptop - isso definitivamente vai funcionar para você. Obrigado por toda sua ajuda.

Para limpar sua entrada no Grub, você deve decidir qual menuentry remover. Primeiro, vamos editar o script de arquivo personalizado no diretório /etc/grub.d e conter o mesmo conteúdo de seu grub.cfg .

gedit /boot/grub/grub.cfg

Copie todo o conteúdo e vá para o arquivo /etc/grub.d/40_custom

sudo gedit  /etc/grub.d/40_custom

Anexe o conteúdo copiado às linhas fundadas no 40_custom.

Agora, neste arquivo personalizado, basta remover todas as entradas do menu que você não deseja que apareçam no menu do Grub. Certifique-se de remover o nó do menuentry que é delimitado por {}

Agora, quando terminar, salve o arquivo 40_custom e saia do gedit

Em seguida, execute o comando:

sudo update-grub

Este comando criará um novo menu de inicialização no arquivo /boot/grub/grub.cfg que contém os itens de menu personalizados que especificamos.

Você pode verificar, antes de reinicializar, apenas para ter certeza, usando o comando: gedit /boot/grub/grub.cfg. Isso abrirá o arquivo no modo somente leitura.

Se o arquivo for o esperado, vá em frente e reinicie, caso contrário, verifique onde você está com erro.
