I have an old Win XP Professional 32-bit machine. Intel Pentium(R) 4 CPU 2,4 GHz and 1,25GB RAM. When I try to install Ubuntu 14.04 from DVD I get this message: This kernel required an x86-64CPU, but only detected on i 686CPU unable to boot please use a kernel appropriate for your CPU. What can i do?

    I sounds like you've downloaded the 64bit Ubuntu. You need to download and install the 32bit Ubuntu.

  • Mitch is right. My answer is provided that 32 bit is the one you are using and it still doesn't work. Dec 16 '14 at 11:16

Your processor only supports 32bit operating systems.

You need to download a 32bit Ubuntu version as @Mitch stated in the comments.


You may have a setting called Intel Virtualization Technology or AMD V, for those respective boards. Enable this setting.

Where can you enable it from? Its in the BIOS. Browse around, find Virtualization Technology/V and enable it. Restart and try again. You should be good to go.

Hope this helps.
