Grub2 boot loader doesn't appear on boot

Question

Okay, install goes smoothly every time. No issues on that end. I let Ubuntu decide where to place the boot loader. It's usually /dev/sda.

The issue I have is the boot loader. Grub, does not show up when I boot my machine. It automatically boots into Ubuntu without any action from my part. So I do not see a Grub2 prompt.

Should I have installed the boot loader into a different partition to get the Grub menu appear on boot?

Solution

Hold the shift key down as you boot and you will get a menu.

If you want to change that behavior, you need to edit /etc/default/grub

# Graphical
gksu gedit /etc/default/grub

# Command line
sudo -e /etc/default/grub

And comment out GRUB_HIDDEN_TIMEOUT=0 (add a # at the front of the line)

Like this

#GRUB_HIDDEN_TIMEOUT=0

See : https://help.ubuntu.com/community/Grub2#Hidden

Save your edit and then run

sudo update-grub

If you wish, you can install StartUpManager which gives you a graphical method of configuring grub
