http://askubuntu.com – I am trying to install Ubuntu 12.04.1 for the first time on my laptop. When I select "Install on disk", it gives me this error message. This kernel requires the following features not present on the CPU; pae Unable to boot - please use a kernel appropriate for your CPU. I get this message both when attempting to install from a USB drive and a CD. Just in case it matters, my laptop is a Dell Inspiron 600m. It has an Intel Pentium M chip. (HowTos)
