If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the i386 images instead (choose this if you are at all unsure). Please take into account that the AMD64 releases should only be considered for those computers based upon AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). For those who need them, here are the official URLs to download the ISO images for all the most recent Ubuntu releases (desktop & server, i386 or AMD64).
