Wether you want to know it or not, there is an operating system war going on these days. Most of the fight is between the following OSes : Windows 8, Mac OS X and Ubuntu Linux. Ubuntu is an underdog in this fight. It really worth trying it as it look more and more like an easy operating system to work with. Today we will teach you how to multi-boot your current Windows OS along with Linux Ubuntu 13.10
What is multi-booting ?
Multi-booting is the act of installing multiple operating systems on a computer, and being able to choose which one to boot when starting the computer. The term dual-booting refers to the common configuration of specifically two operating systems.
Backup before Installation
It is important to back up your files to an external backup medium before attempting a dual-boot installation (or any other hard drive manipulation), in case your hard drive becomes corrupted during the process. External hard drives, USB flash drives, and multiple DVDs or CDs are all useful for this purpose.
Install Ubuntu after Windows
A Windows OS should be installed first, because its boot loader is very particular and the installer tends to overwrite the entire hard drive, wiping out any data stored on it. If Windows isn’t already installed, install it first. If you are able to partition the drive prior to installing Windows, leave space for Ubuntu during the initial partitioning process. Then you won’t have to resize your NTFS partition to make room for Ubuntu later, saving a bit of time.
When a Windows installation already occupies the entire hard drive, its partition needs to be shrunk, creating free space for the Ubuntu partition. You can do this during the Ubuntu installation procedure.
How to do it
1. Create Separate Partition.
You can create separate partition. If you don’t want to do so you will have the option Install Ubuntu alongside them.
1.1 Go To “Computer Management”.
1.2 Go To “Disk Management”.
1.3 Right Click on Disk you want to Partitioned, Select “Shrink Volume”.
1.4 Enter the amount of space to shrink in MB. Then click Shrink. This will create New Partitioned Disk with disk amount entered by you.
2. Setup Boot Order in BIOS (CD/DVD-ROM /Hard Drive etc.)
Some computers are set to boot directly from the hard drive. This should be as simple as entering the BIOS, enable booting from the CD-ROM drive, and making sure that the CD-ROM is before the hard drive in the boot order.
The most common way to enter the BIOS is to press the DELETE key when the computer is first booted (this seems to be becoming standard). On other systems it could be a different key, or combination of keys like ESC, F1, F2, F10, F12, Ctrl-Esc, Alt-Esc, Ctrl-Alt-Esc, Ctrl-Alt-Enter. You might have to press, press and hold, or press multiple times. The best way to find out the details of that is to look in the user’s manual or search the manufactures website. A few different Bios screens.
2.1 A common power-on BIOS screen (Notice the ‘press DEL/F10/F12/etc. to enter into the BIOS).
2.2 A typical BIOS boot menu screen.

3.3 Make sure that your BIOS (boot order) is set to boot from a CD/USB before a hard drive.
3.4 Choose the Try Ubuntu option in order to check that your hardware (screen, keyboard, internet…) is correctly recognized by Ubuntu.
3.5 When you are ready to install Ubuntu on your hard disk, click the Install Ubuntu button. The installation wizard will appear:
3.5.1 Selecting Language.

– If you want to manually setup your partitioning scheme, select the Something else option.
Click Install now. From this point, the installation cannot be cancelled. Few additional parameters need to be setup. The Where are you? window appears.
