well, you have taken the first step on exploring outside windows, well, first you can visit any of the major companies that makes linux.
redhat, caldera, suse, corel
they offer their distro for free to download.
well then, you have to partition your hd, into two pieces, one for linux and one for windows, after that, you need to burn your linux onto a cd and make an iso.
ok here is how i did it. i have suse linux 6.3, and all i did was put the cd in, and restarted the comp, then linux guided me all through a "windows" like guide.
warning warning: make sure to back up all your stuff before doing this, i love a hd that way 🙁 sniff sniff, ohh well.
theres tons of info on this boards as well as all over the net, and linux zealots are always willing to help you, just dont let them convince you to delete your win partition.
disclaimer: this post is a rather cut and dry version of what you are supposed to do.
