Change the GRUB Menu Timeout on Fedora 14, Fedora 15
When your system boots, you will see the GRUB menu, or if you’ve enabled the menu to show by default. The only issue for this is that the default timeout. So you may want to change this timeout. Increase or Decrease the time,both are simple.
Open up the /boot/grub/grub.conf file in any text editor. For this you need Super User Permission
i am using Gedit
Now find the section:
and now replace the 0. The timeout value is in seconds so replace it some other value
as i want it for 5 seconds, so i used
And save the file, and when you reboot you will have that many seconds to choose the menu item you want.
