Startupmanager - A very usefull tool for grub configuration on debian flavors of linux

Startup-manager is a GUI tool to configure settings for Grub, Grub 2, Usplash and Splashy. It provides a menu interface which allows you to set boot menu options such as the default operating system, Which kernel you want to boot into always, menu timeouts and displays  etc. Startup-manager accomplishes this by translating your GUI inputs into bootloader settings without the need to manually edit the bootloader file (in Ubuntu, normally /boot/grub/menu.lst).

To install the startup-manager application on your ubuntu.


#> apt-get install  startupmanager

Note : Just to ensure the safety, keep a backup of original menu.lst file


#> sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.orig
