To install Ubuntu on your computer or laptop, you need three things.
Ubuntu installation image.
A USB Flash drive/Pendrive or a CD.
Step One : Download the Ubuntu Disk Image
Go to Ubuntu download page and download the CD image (.iso) file from there. If you are an Indian user, you can download it from Indian mirror for better speed. The name of the file will be something like ubuntu-11.10-desktop-i386.iso. Also if you have more than 2 GB of RAM, you can also obtain the 64 bit versions from there. If you already have a Ubuntu CD along with you, you can skip to step 4.
Step Two : Download PenDriveLinux Software
Once you have the image, go to PenDriveLinux and download the software. Its a just 1 MB software that helps you to install Linux from your pen drive. Unlike Windows, you can also use your USB/flash drive to install Linux. Or if you don’t have a USB port, and would like to install Linux from CD/DVD, just write the .iso file to a CD using Nero.
Step Three : Extract the bootable image on your pendrive.
Open the PenDriveLinux software that you just downloaded and accept the license agreement. In the select Linux distributions, select Ubuntu 11.10 or the version/OS you would like to install.
Step 4: Tweaking the BIOS to boot from Removable Device/Pendrive
Insert the pendrive or the CD in your drive and restart your PC. If your BIOS setting permits external booting, you will find Ubuntu booting on your PC (a glowing brownish screen). If it doesn’t you need to tweak your BIOS. Restart you PC again and while it is booting, press the Del key (or the corresponding key as mentioned in your motherboard manual). A blue or black screen will appear. Using arrow keys, go to the boot options menu. From there, select the first boot priority to removable device or CD drive. The picture below will help you.
Step 5: Booting Up and Installing Ubuntu

Click on install Ubuntu, and the setup will check if your PC has enough requirements for its installation. You will need at least 4.4 GB disk-space for a successful installation.
