I would like to create an USB Live and I have intel processor which supports 64 bit systems but I dont know which version of Ubuntu best is for me..actually I have downloaded an Ubuntu iso file which is called "ubuntu-12.04.1-desktop-amd64.iso" but the word amd in the name made me confused.I dont remember which link I used .
I will use Universal USB installer so if I choose Ubuntu 12.04 desktop , how can I make sure that I am going to download 64 bit version of it?
and i386 means 64 bit?
thanks
