From the https://help.ubuntu.com/community/Grub2

You can change which kernel grub boots to during the computers start-up.

As the computer starts up.

Hold down SHIFT to display the menu during boot. In certain cases, pressing the ESC key may also display the menu.

You should now see the the grub menu. Use the arrow keys to navigate to the advanced options and choose the kernal you want to boot.

Or try the ubuntu community documentation here. https://help.ubuntu.com/community/Grub2/Setup#Configuring_GRUB_2

This is from THIS post by nelaarThen follow the instructions in this post to fix the menu entry.

You can install Grub Customizer by:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

and change the position of entries in the Grub menu. From this you can choose to make the latest kernal as the default entry.

  • Just a side note: grub-customizer broke my grub install (made it black with no boot options) not saying noone should use it as it is known to work, just a word of caution – Mark Kirby May 9 '15 at 7:58
  • grub-customizer is for a desktop. You can not run this from the command line. – DanielaWaranie May 12 '17 at 15:27
