How to create Linux partition on windows as dual boot system

If you are using windows operating system on your computer and want to install Linux also as dual boot system   but you are new to Linux environment  and dont know nothing about how to partition hard disk ,  this blog is the right place for you .

Lets learn how to install Linux  (Ubuntu 11.10) step by step on you system.

Step 1.  (Preparing the Bootable Linux CD/ Pendrive)
Go to  http://www.ubuntu.com/download/ubuntu/download to download Ubuntu Linux

Step 2.  click here to create a bootable pen drive

Step 3.(Back up you data from Last drive )

I will explain this with an  example
Let's assume that you have 240 GB hard disk in your system .

Drive Letter       Space              Label
C Drive                50 GB               [Window]
D Drive               90 GB               [Data]
E Drive             100 GB               [Movies]

Now move   all the data from E Drive[Movies] to D Drive [Data]


Step 2.(Partitioning the Hard Disk )

Now your  E drive is empty   after moving all data to D drive .
Now we want to make a below partitions for Linux

20 GB drive for Linux  and other software installation and user data
  6 GB Partition for Swap  drive  [Swap drive size should be at least double of your system RAM size, I have 3 GB RAM in my system in this example ]

Go to Control Panel --> Administrative Tools -->        --- > Disk Manager
Divide/ Resize  the E drive into 74 GB + 20 GB + 6 GB sizes = 100 GB (total size of E drive)


Restart the system and boot with Bootable Pendrive / CD

For 20 GB drive select " / "  from mount dropdown  box  and ext3  file format
Example : /dev/sda6 ext3 52428 MB


For   6 GB drive select Swap                                                                          
Example : /dev/sda7 swap 5494 MB




 

why Ubuntu ( Linux ) is better than Windows

Ubuntu ( Linux )  is better than Windows due to  following reasons:

- The hard drive does not need to be de-fragmented
- Hard drive can be encrypted for extra security
- Faster file system (EXT4)
- No viruses, no malware
- Stable stand-by mode
- Fun to use
- Continues to work great even on older hardware
- Excellent support through the Ubuntu user community
- Network friendly
- Ubuntu is free !
- Linux has no registry
- 35,000 plus free excellent  softwares available in linux
- Never needs to be re-booted
- No annoying pop-ups telling you that an upgrade is available. Ubuntu updates all
  installed software in one single action.
- Around 300 different Linux distributions available (like windows have win95, 
   win98,    win2000, winXP, Win7, win8)
-Many windows based software can also be run using Wine utility



Different Linux distributions use different desktop environments ( windows have only one desktop look and feel environment  ). The two big ones are KDE and GNOME.  Other environments  are :

GNOME
KDE
LXDE
FLX
XFCE
Fluxbox
Openbox
Kubuntu
KDE plazma desktop, (http://it-diary.com/linux/ubuntu-linux/install-kde-plasma-desktop-ubuntu-11-10/)
Unity
Classic
GNOME Shell


Razor-qt
Awesome WM
E17
Mate
Cinnamon

 All of the above Desktop Environments are customizable. You can add Panels, launchers, applets, indicators, you have a notification area, etc.

Extra info :

Debian and Redhat distributions ( in short "distros" )  use the same kernel and GNU parts, but differ chiefly in packaging. Debian has its own called Deb and Redhat uses RPM. Packaging is confusing for new users. It is essential to know what it is because that is how your applications are installed.


First we generally don't download Debs or RPMs. We get them from controlled sources that are maintained and secure called repositories.

Repositories are maintained by the distribution and you can use them with confidence that they are free of viruses and malware and are meant to work with your version of their distribution
