Eu tentei todos os métodos que vem no google procurar por "ocultar o menu grub no início do computador", mas ainda sem sorte, eu acho que as coisas funcionam de forma diferente no Ubuntu 15.04?
este é meu grub

o que fazer no Ubuntu 15.04 para inicializar imediatamente sem mostrar o menu de inicialização?
mais alguns detalhes: Eu corri sudo update-grub
depois de fazer alterações no arquivo grub. Minha BIOS é UEFI
UPDATE: Eu triplo boot Ubuntu (padrão, já que eu uso 90% do tempo), arch linux, windows (para jogos ocasionalmente). então eu seleciono o Ubuntu na maioria das vezes eu quero inicializar diretamente para ele, mas ocasionalmente se eu quiser inicializar em outro sistema operacional, eu gostaria de " apertar shift key e ver o grub e selecionar o sistema operacional desejado ", é por isso que eu quero esconder o grub
UPDATE2: quando eu definir o timeout do grub para 0, ele se torna 10sec na inicialização, não sei porque ...
