NOTE: Tested on Ubuntu 9.04
Boot into Ubuntu
Open a new Terminal Window
Type in the following command: {codecitation style=“brush: bash;"}sudo gedit /boot/grub/menu.lst{/codecitation}
Now gedit will open.
Located the following lines:
## timeout sec # Set a timeout, in SEC seconds, before automatically booting the default entry # (normally the first entry defined). timeout 10
Change timeout 10 to the desired timeout seconds. eg. timeout 4
Save the file and exit.
Now the next time you Boot your PC the timeout change will take effect.
