Graphical grub2 Configuration Manager - Grub Customizer

The goal of Grub Customizer is to create a complete and intuitive graphical grub2/burg configuration interface. The main feature is the boot entry list configuration - but not simply by modified the grub.cfg: to keep the dynamical configuration, this application will only edit the script order and generate proxies (script output filter), if required. To get more information about how it works, look here: https://answers.launchpad.net/grub-customizer/+faq/1355.
Version 2.0 introduces the ability to change the grub2/burg setting like the default entry, timeouts, menu visibility, screen resolution, background image and colors (grub2 only) and much more.

Since version 1.5 you can use it to repair and configure grub2/burg using a live cd (and Grub Customizer, which has to be installed as usual at the live system before using it). All the required partitions will be automatically mounted when choosing the root partition and some sub partitions on the "partition chooser" (a dialog which pops up, when you start Grub Customizer inside a live system).

Grub Customizer Installation:
Open a terminal (Applications > Accessories > Terminal) and type following commands:

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

After successful installation you can open the Grub Customizer from Applications > System Tools > Grub Customizer or you can use the command: gksu grub-customizer from the terminal

For those interested in how the application actually accomplishes the tasks, please refer to Daniel's Grub Customizer FAQ.
