Dealing with Linux system files means complete suicide For novice users! ^_^ , Specially when it comes to the boot-loader.

When you have Windows and Linux on your system and you wanted to set Windows as your default operating system in the boot loader…..

So, you somehow found the folder with the GRUB configuration files and started editing it. After your done, you proudly re-started your system and was greeted by a boot-loader error! Boom! Now you can’t access any OS in your system!

I think this is the normal scenario when it come to editing the boot-loader. For me, earlier, this was my favorite method! But, actually, you don’t ave to go into that much trouble to edit your boot loader. In Ubuntu, now you can use a small software called the StartUp-Manager to do the job. So, want to try it out? Lets see how to use it.

How to Use the StartUp-Manager

Download: https://launchpad.net/startup-manager/

First to install it, open the terminal (Applications > Accessories > Terminal) and enter the following command :

sudo apt-get install startupmanager

Next go to, Main menu : System > Administration > StartUp-Manager
Now you’ll see a screen as below :

1) Time : The time to display the boot-loader in seconds.

2)The default operating system. The OS which will be loaded if you don’t do anything within the given time frame.

Note : Do not change the other settings if you don’t know what your doing!
