I currently have Ubuntu 11.10, and I finally decided to upgrade. So I downloaded the .iso file from the site (Ubuntu 13.04, 32 bit), and put it on a 2gb thumb drive. I booted from the thumb drive, and it gave 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.

I saw a post suggesting that I use Update Manager, but I don't want to end up downloading the update, then when its half way through the install process, my computer might crash, and then i would lose all my data etc (I don't know if that is a proper assumption, because I don't know much about Ubuntu)... Can I use the minimal CD talked about it https://help.ubuntu.com/community/Installation/MinimalCD ? I don't want to mess anything up with a stupid mistake, so thanks for the help. (Btw, I have a dual boot with windows XP and Ubuntu 11.10, if that makes any difference). I also understand that this is similar to the question asked in Can't install 12.04 server under Intel Pentium M , but

my processor is: Intel® Pentium(R) M processor 1.10GHz

Ubuntu 12.10 and 13.04 do not support NON-PAE CPU's

PAE releases are available in 13.04 (and 12.10), but you could try Fake-PAE.

13.04 32 bit ISO require your CPU to have Physical Address Extensions, or PAE. "PAE is provided by Intel Pentium Pro and above CPUs, including all later Pentium-series processors (except most 400 MHz-bus versions of the Pentium M)." - If you have a NON-PAE CPU and would like to install Lubuntu 12.10, please see this link or you can use 12.04 instead.1

    Basically, I can install 12.04, but nothing later than that. Did I understand correctly? And how could i use Fake-PAE? – Moose May 02 '13 at 10:05
  • Correct. To use Fake-PAE, just click on the link in the answer. – Mitch May 02 '13 at 10:15
  • I installed fake-PAE, now do i just have to use update manager? (edit: Sorry, i didn't click on the link before asking... :P fail...) – Moose May 02 '13 at 11:53
