Boot-Repair is a simple tool to repair frequent boot issues you may encounter in Ubuntu like when you can’t boot Ubuntu after installing Windows or another Linux distribution, or when GRUB is not displayed anymore, or when some upgrades breaks GRUB, etc. Boot-Repair lets you fix these issues with a simple click, which (generally reinstall GRUB and) restores access to the operating systems you had installed before the issue. You need to boot from your live stick of Ubuntu again and then run these commands in Terminal:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

Grub Customizer is a GUI configuration tool to allow users to change the Grub 2 settings without using the command line. The application allows the user to add, remove, freeze, rename and reorder boot menu items. It will also allow changes to the Grub 2 configuration settings such as background image and menu timeout. For long-time users familiar with StartUp-Manager, this application performs many of the same capabilities with additional options. It also makes convoluted guides such as my “Grub 2 Title Tweaks” unnecessary for all but the most devoted command-line enthusiasts!

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

But hopefully, if all went well, you should now be logged into your brand new Ubuntu 14.04 desktop at this point.
