Wubi is an Ubuntu installer for Windows that lets you install and uninstall Ubuntu from a Windows desktop. Wubi adds an entry to the Windows boot menu which allows you to run Linux. Ubuntu is installed within a file in the Windows file system (a loopmounted partition), this file is seen by Ubuntu as a real hard disk. That way the hard drive does not have to be repartitioned before the Ubuntu installation. The resulting Ubuntu installation is a “real” Linux system, not just a virtual machine. Wubi makes it easy for Linux newbies to play around with Ubuntu.

1 Preliminary Note
I have tested this on a Windows XP Professional desktop.
2 Downloading Wubi
Go to http://wubi-installer.org and click on the Download (Beta) button:
Download Wubi to a folder on your Windows system:
3 Installing Ubuntu
Open Windows Explorer and go to the folder where you saved Wubi. Double-click on the Wubi icon:
Wubi starts. You can now configure your future Ubuntu installation, i.e., you can specify the location of the Ubuntu installation on your Windows partition(s), the size of the Ubuntu installation, the Ubuntu flavour (Ubuntu, Kubuntu, Xubuntu, Edubuntu, UbuntuStudio), the language you want to use on your Ubuntu desktop, and a username and password for the Ubuntu system. Click on Install afterwards:
Wubi downloads the CD iso image of the Ubuntu flavour you’ve chosen. This can take some minutes, depending on your bandwidth:
Afterwards, Wubi asks you to reboot the system. Please do so now:
When the system reboots, you should now see a boot menu from which you can select your Windows system and the new Ubuntu system. Please select Ubuntu and press <ENTER>:
Because Ubuntu isn’t installed yet, you should now see the Ubuntu installer (text mode). It installs your Ubuntu desktop according to the settings you’ve made in Wubi before – no interaction is needed from your part:
After the installation has finished, the system reboots. At the boot menu, please select Ubuntu again:
Now your new Ubuntu desktop system should boot:
Type in your username and password (the ones you specified in Wubi before):
This is how your Ubuntu desktop looks. You can now use it like any other Linux desktop:
There’s even an icon for your Windows partition on the desktop. If you double-click on it, you can browse your Windows partition:
Now let’s see if our Windows desktop is still working. Shut down the Ubuntu system…
… and boot your Windows system:
Windows is booting:
As you see, your Windows desktop is still working as before:
4 Uninstalling Ubuntu
If you like to uninstall Ubuntu, open the Control Center in Windows:
Go to Software:
In the Software window, you see a list of all installed software. Find Wubi and click on the Modify/Uninstall button:
You can now choose if you’d like to back up the downloaded Ubuntu files and the Ubuntu documents (in case you want to reinstall Ubuntu again later on). Make your selection and click on Uninstall:
Wubi is now being uninstalled. Afterwards, you can close the uninstaller and leave the Control Center:
Now when you reboot the system, the boot menu is also gone (because only Windows is left on the system), so your system is in the same state as it was before you installed Ubuntu.
