I just upgraded from 11.10 to 12.04 and I have to use an older version of the kernel when I start my computer. When I restarted my computer for the first time it wouldn't bring me to the login screen. Then I restarted it and tried an older version of the kernel and it worked! Does anyone know what the problem would be?

I get the 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."
How do I use a different kernel? Please keep answer simple, I am not very technical. Thanks

Download the Xubuntu ISO (http://cdimage.ubuntu.com/xubuntu/releases/precise/release/) as that uses the non-pae kernel.
Good Luck

Try adding "nomodeset" to the Grub command line.
Install Grub Customizer (http://ubuntuforums.org/showthread.php?t=1664134&highlight=grub+customizer+drs305) and add the nomodeset next to the "quiet splash" in the Grub kernel boot line.
Good Luck

Thanks plucky, worked great. I found out I can also run "sudo apt-get install ubuntu-desktop" in terminal after installing Xubuntu to end up with standard Ubuntu 12.04.
