[how-to] Change the GRUB Menu Timeout on Fedora 17

June 17, 2012

When your system boots, you’ll see the GRUB menu, or if you’ve enabled the menu to show by default. The GRUB menu is displayed for a predetermined number of seconds. However, on Fedora 17, the default timeout is only 5 seconds. So you may want to change this timeout. Increase or Decrease the time, both are simple.

Step 1. Backup the /etc/default/grub file.

# cp  -v  /etc/default/grub  /etc/default/grub.bak

Step 2. As the root user, open up the /etc/default/grub file in your favorite text editor:

# gedit   /etc/default/grub

Now, edit the “GRUB_TIMEOUT” line to set the time:

Next, save the file and exit.

Step 3. In terminal, run the following command to generate settings from /etc/default/grub file.

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

Step 4. Reboot your system.

Good luck for you!
