How to get ubuntu precise running on a computer that does not support APCI

From the following posts I was able to get a computer to first install and then boot after installed due to the APCI errors it was getting.

hit F6 when the cd reaches the purple screen with the human and the keyboard. This should bring up the usual boot menu with all the options for what to do with the live CD. Here press F6 again, and boot options will come up. The “acpi=off” option should allow you to boot. Now you can install if you want to. You will need to also fix the install as changing the installer does not also set the same requirements on the installed os.

Hold “Shift” while booting and you will be able to edit the boot options. Selecting the version you want to boot, and pressing e on it. In these boot options, add “acpi=off” to the end of the line that starts with “linux”. The should enable you to boot into your installation.

Lastly, you need to make this change permanent. Once booted, navigate to /etc/default/ and edit the “grub” file.
Look for the line that says “GRUB_CMDLINE_LINUX=”””
Change it to GRUB_CMDLINE_LINUX=”nolapic”

Now you should be able to boot this box every time.
