Kernel won't boot on start up of first time install "this kernels requires an x86_64 CPU

Question

At boot time I get this message:

This kernel requires an x86-64 CPU, but only detected an i686 CPU.
Unable to boot- please use kernel appropriate for your CPU 

Answer 1

It appears you have a 32 bit processor so you need to use 32 bit (i386) version of Ubuntu

http://releases.ubuntu.com/16.04/ download the i386 version

http://releases.ubuntu.com/16.04/ubuntu-16.04.2-desktop-i386.iso

Or you can use 17.04
