Up until about 6 months ago, I was a MS user. I knew and understood the operating system, but I got sick of all the bullshit associated with it and needed a switch. I've been through about 12 - 15 different distros, looking for the right one for me, and I haven't had ANY problems installing them. I find that if you actually ummm....READ the instructions and follow them, it is quite easy.
Even if doing a text-based install is too difficult for a XP user, who'se obviously attracted to the bright colors and flashy graphics, much as a mentally retarded person would be, I've found that the blag! distro has a very nice GTK based installer, that does everything for you, right down to creating the swap partitions. Just a few simple clicks. Come to think about it, VectorLinux does it too. Boy, I think Knoppix and OverClockix were really easy to install.
FreeBSD gave me some problems, but after a quick scan of the online install guide, I found out about the automatic partitioning of that too.
What I'm trying to say is, if you have been trying for FOUR years, four f*king years, you have some serious problems. There is a good chance that you shouldn't even own a computer right now, do to the inherant safety hazards that you pose to yourself and others with your ignorance.
