Full Installation
There are three main types of full installation you can make (other than via a virtualizer):
As the sole operating system, taking over all hard disk partitions
As part of a dual- or multi-boot setup with its own hard disk partition
Using the Wubi program to run Ubuntu from within a Microsoft Windows virtual disk, without any hard disk repartitioning
The most efficient way to run Ubuntu together with Windows is option 2. But installation can take a very long time to complete because the Ubuntu installer needs to repartition the hard disk to make room for the new operating system, potentially moving hundreds of gigabytes of data around.
Wubi offers the fastest installation possible, because Ubuntu installs in just a few files within your Windows filesystem. Wubi also changes your boot menu options, adding Ubuntu as an alternative operating system that you can select with the cursor keys and Enter at boot time, just as with a full dual- or multi-boot install. Therefore, I will cover Wubi first.
Installing Ubuntu Under Windows
Wubi is a powerful program that creates a virtual hard disk under Windows and runs Ubuntu from there as part of a dual- or multi-boot operating system.
Performing the installation
To perform the installation, as it will not run directly from the DVD, drag and drop the following two files from the distros folder of the DVD onto your Windows desktop:
wubi.exe
