One of the reasons I bought this computer, is because it came with Windows XP, which I have on my PC.

I can't seem to find Windows XP anyplace, but have something called ubuntu. Is this ubuntu my start up system? Can anyone tell me anything about ubuntu.

Also, do I have to be connected to the internet to access either ubuntu, or XP?

Last question. Can I use a spliter to get internet on both of my computers at once?

Thanks,
Ralph
