My processor is 64-bit - does that mean I need the amd64 image?
I downloaded from http://www.ubuntu.com/download/server. I didn't know it was not for Intel system until I checked the file name this morning. The file name is ubuntu-12.04-server-amd64.iso, so it is for AMD system. The web site does not say anything about system architecture, why doesn't it?
Where could I download one for Intel system?
