Se eu posso rodar grub no cli, isso significa que meu pc ainda irá inicializar quando eu reiniciar?

Question

Eu executei grub , que funciona bem e grub-emu , que retorna isso:

error: no suitable video mode found.
error: sparse file not allowed.
error: can't find command 'linux'.
error: can't find command 'initrd'.

Press any key to continue...
Failed to boot both default and fallback entries.

E depois mostra:

Issosignificaqueareinicializaçãofuncionará?

Acabeideatualizarogrubporacidente(tentandocorrigirumproblemasemanalemqueomeudiscoraiz torna-se somente leitura ) e estou preocupado que, se eu reiniciar meu servidor, ele não inicializará novamente (qualquer maneira de confirmar ou negar isso)?

update-grub retorna:
