to modify the timeout (make boot faster)

grub2 debian boot screen splash image

on newer linux

tested on : (# Debian 8 „Jessie“ Linux DebianGiada 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt7-1 (2015-03-01) x86_64 GNU/Linux):

edit this config file:

vim /etc/default/grub

# modify 1 = wait 1 second until entry 0 is booted
GRUB_DEFAULT=0
GRUB_TIMEOUT=1

# then run under Debian7-8/ubuntu
update-grub2

# centos7
grub2-mkconfig 
grub2-mkconfig -o /boot/grub2/grub.cfg

# to generate new /boot/grub/grub.cfg

on older debian / grub1

„wheezy“? „squeeze“?

checkout this config file:

vim /boot/grub/menu.lst
