This is my first attempt at installing Ubuntu (or any Linus distro for that matter). I dloaded both the "live" and the "install" iso files from Ubuntu.com. I have reset my BIOS to boot from the DVD drive. When I restart my computer nothing happens...the system proceeds directly to Windows (XP Pro BTW). I ran md5sum on the "live" version and was given a long string of characters but no error messages of any sort. Is there something that needs to be done to the iso file prior to burning it to CD? Someday I hope to be a Linux newbie, right now I'm still a zygote dreaming of the day I can excise the cancer from my hard drive that is Microsoft Windows.
