When trying to install Ubuntu 14.04.4 LTS Server from a CD, the error is written:

This kernel requires the following features not present on the CPU: pae сx8 Unable to boot - please use a kernel appropriate for your CPU.

How to fix it?

  • enable the virtual box in the processor settings tab "Enable PAE / NX" or switch to bios - if it is an iron computer, well, or build a custom kernel. there are few details in your question, what is the percentage, virtual or real server, etc. why do you need 14.04 outdated? - strangeqargo
  • This installation is not on the Virtual Box. Real server. In the transition to 16.04 there were problems with installing programs. Motherboard: VIA EPIA-ML - Anton Vidovich
  • Processor: VIA C3 667 MHz - Anton Vidovich

    no way. well, or rather, you need to compile the kernel of ubunt with the CONFIG_X86_LONGHAUL flag, rebuild the distrib with this kernel and hope that everything will take off ( cateee.net/lkddb/web-lkddb/X86_LONGHAUL.html ) - strangeqargo

    I do not advise, in fact, on such a procedure it will be necessary to reassemble the entire system, I suspect. you in gentoo or something like damn small linux, rather - strangeqargo
