Ok então,
Nota que estas alterações funcionam até à próxima actualização do kernel.
Se quiseres fazer algo mais definitivo, é um pouco mais complicado, mas podes ver em

Que eu saiba, o SUM ainda não funciona bem como GUI para o GRUB 2, mas de qualquer das formas, fica aqui o link:

Ok, então vais editar esse ficheiro escrevendo na consola:
$ gksu gedit /boot/grub/grub.cfg &
(Não escrevas o $, isso serve só para indicar que é um comando de consola)
Vai abrir o Gedit, depois de pedir a password do root.
Agora substituis o que lá por isto, que está entre ---SOF--- e ---EOF--- (não incluas estas linhas que contêm estes textos, são só para saberes onde começar e acabar a copiar)
