Inicializando através do USB e eu tenho que puxar o pen drive e colocá-lo de volta na inicialização

Question

Eu tenho iniciado a partir de USB por algum tempo, e toda vez que eu reiniciar ou iniciar após um desligamento, os scripts de inicialização (grub?) ficam presos. Parece que o drive USB é desmontado em algum ponto do script, e eu tenho que removê-lo fisicamente e colocá-lo de volta. Quando faço isso, tudo continua normalmente. Demorei um pouco para descobrir que tinha que fazer isso, mas agora que sei, acho isso muito irritante. Eu gostaria que ele fosse iniciado sem que eu precisasse fazer nada além de pressionar o botão liga / desliga ou reinicializar a partir do terminal.

Sou um amador e não sei realmente por onde começar este. O que seria útil para a comunidade para responder a essa pergunta?

Para começar, aqui estão os resultados relevantes de dmesg | less :

Eu vi esse comportamento uma vez em uma máquina cuja enumeração de disco não era consistente. O grub.cfg gerado tinha os números de disco incorretos e não funcionava até que o USB fosse removido e reinserido, forçando um novo número de disco, que então funcionava. Dê uma olhada no seu grub.cfg e tente apenas editar os números hd. Quando o USB funcionou, foi dado sde, então tente hd4. Uma vez em execução, você pode tentar uma correção permanente com

sudo update-grub

mas como geralmente é uma questão de tempo, não há garantias de que algo seja permanente. Além disso, você pode tentar outro USB, eu só tive o problema em um dos meus, então talvez fosse lento ou algo assim.
