This tutorial will show you how to install Ubuntu 12.04 using a Live CD along with Windows 7 x64.
We assume you are currently running Ubuntu 11.10 installed using Wubi. We also assume that you have Windows 7 x86 installed in C:/ drive which have 50 GB free Space. (Total size of C:/= 70 GB)
First thing first, You need to check your computer's hardware compatibility. Burn the Ubuntu 12.04 ISO using Nero or K3b to a CD (Yes burn on a CD, Not on a DVD). After burning completes boot your computer using it. Check apps are working correctly or not. Make sure all hardware is compatible. Check whether the display is working good or not. How the blue-tooth is working etc. After you finish proceed to the next part:
This tutorial is under construction.
The first thing we need, is to make some space to install Ubuntu 12.04 side by side of Windows. We can either install Ubuntu 12.04 on a primary partition (sda2) or in a logical partition (sda5). (Remember some OS needs to be installed in the Primary partition(sda1), though here is no problem in installing Ubuntu 12.04 LTS on a Logical partition. It works fine.)
Freeing up some space:
We can free up some space either by shrinking the primary drive (C:/) to a minimum of 32768 (32 GB) or deleting a logical drive or some portion of logical drive (F:/).
Now if you wish to install Ubuntu on a primary partition then you will need to shrink the C:/ drive within Windows to make some room for Ubuntu 12.04.
To do this: Login to Windows. Open Disk Management.
