I am a big Ubuntu fanboy. The Ubuntu (and other *buntu flavors) developers really got the distribution right. I have 3-4 different Ubuntu-related RSS feeds in my reader. One of them told me about Issue 8 of Full Circle Magazine, a free Ubuntu magazine. Inside there was an article on an interesting new project, Wubi, an Ubuntu installer for Windows.
Warr? NO WAI! It's true, the project is an installer which creates a very large file 4-20GB or so that serves as the base for your Ubuntu installation. There's no partitioning and nothing invasive to your comfy little Windows home at all. You download an .exe installer, fill out all the details of your installation, "click the Next button" and away you go.
It adds Ubuntu to the Windows boot menu and lets you choose between Windows and your new Ubuntu installation (defaults to Windows). From there on out you boot into Linux and it's just as if you would have gone through all the work of partitioning, etc.
Here's all the magic which makes Wubi possible. The guide says that when you wish to uninstall Wubi just boot into Windows and remove it using Add/Remove Programs just like you would any other piece of software (
I haven't confirmed this yet, as I have not uninstalled Wubi yet I did a test of this on my box the other day. Uninstallation works as advertised).
This is an excellent way to lower the barrier of entry to Linux for Windows users. No need to hassle with the slowness of a Live CD, or the configuration of a virtual machine -- Wubi rules.
(Here's small screenshot of my success. However, it basically just looks like any other initial Kubuntu screenshot.)
