Há alguma coisa a ser feita para diminuir o tempo de boot?

Desde já agradeço qualquer colaboração.

Um abraço!

Pelo jeito, o gargalo é no HD. Quanto mais antigo, mais lento fica o HD. Se tiver incomodando mesmo, recomendo pegar um SSD.

Grato pela atenção!
Mas a máquina é antiga, está funcionando bem e não acho que vale o investimento.
Obrigado.
