CUDS #1 Changing GRUBs Timeout
, 03 Nov, 2010
In my opinion ten seconds are too long. This is the default time GRUB waits until the first listed entry in the boot menu is selected. Of course you can shorten it by typing ↲ but wouldnt it be more comfortable if your pc started fast without the need of you pressing buttons? That is the reason why I always reduce GRUBs waiting time.
With GRUB (version 1.x) it was very easy to change the configuration files. GRUB2 wants you to verify the changes first before applying them. So firstly we have to edit
/etc/default/grub. The value after
GRUB_TIMEOUT= has to be set to the desired time in seconds. To my mind, a second is enough. Using extended kernel options as well as starting other operating systems so seldom, I just interrupt the time by pressing an arrow key when these cases occur.
As already noticed since version 2 you have to enable the changes written in the config file. This is done by the following command:
Now the whole passive boot time should be noticeably shorter.
