I am running Windows XP SP2 (32-bit). I want to ask if I can install Ubuntu 10.04 without removing Windows XP? I mean can I keep both OS at the same time like some people keep 2 Windows?
If you download WUBI from any linux website, you can install Ubuntu inside Windows. No need to repartition your hard drive. When you reboot, and bring up your folder directory, it will be in its own folder on your C drive. Just click click and you are into the full version of Ubuntu. No dual boot needed.
But how then can you access your xp data from inside ubuntu?

I am not so familiar with Ubuntu, but here's the documentation you may be searching for - WindowsDualBoot
