How to install multiple operating system in single computer

Now a days everybody is using more than one Operating System in a single computer based on their requirement. This is called multiboot or dual-boot configuration. Whenever you start your computer, In console you will get option to choose which operating system you want to load. For multiboot or dual-boot you need to install the second OS to separate partition. This is the small geek but a few don’t know how to do that. Now, I’m going to install two operating systems in a single system.

1) Installing First OS

I already installed openSUSE 13.1 on my PC. While installing, i didn’t partition my hard disk properly so/root partition took whole disk space. For multiboot i want a separate partition. So I’m going to resize the root partition using GParted.

2) How to resize active/primary root partition using GParted

Use the GParted to resize active/primary root partition to free disk space.

3) Installation Second OS

Now, I’m going to install Ubuntu 14.04 LTS. Insert your installation media and boot your system.
