Mudar a ordem do boot (Ubuntu)

1 - Abrir o ficheiro que contem a ordem do boot

Code: ~$ sudo gedit /boot/grub/menu.lst

2 - Analisar (a sua configuração deverá ser parecida a esta)

Quote:

kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=e586670d-12df-40fe-896e-7d696797c160 ro quiet splash locale=pt_BR
initrd /boot/initrd.img-2.6.20-15-generic

Já podes gravar e fechar o ficheiro.

Quando reiniciares o computador a ordem do boot já está alterada.
