i get lost on step 2
rename the downloaded "vmlinuz-3.5.0-17-wt-non-pae_3.5.0-17.28_i386" file to "vmlinuz" and copy it to the USB stick, under the "casper" folder, replacing the already existing "vmlinuz" file.
rename the downloaded "initrd-3.5.0-17-wt-non-pae_3.5.0-17.28_i386.lz" file to "initrd.lz" and copy it to the USB stick, under the "casper" folder, replacing the already existing "initrd.lz" file

Well,

the easiest way to install Ubuntu 12.04 non-pae is through another Ubuntu Official flavor that supports non-pae .

Lubuntu 12.04 supports non-pae processors and Xubuntu 12.04 as well.

This thread in Ubuntu-Forums.org will illuminate you about what happen

I would prefer the Lubuntu and I would stuck with it , as a very light (low-resources) desktop environment but you can do anything you want :-)
I assume the PC is old one , because all of moderns PCs supports the PAE feature. So maybe Unity is a bit heavy (?)

If you want to install Unity .. just apply this command in terminal (lxterminal), after you make all updates

sudo apt-get install ubuntu-desktop

and unity should be there.

Have a good Install !

Thanks

Of course if you want the 12.10 version , you can upgrade through 12.04 . But think about this twice , because 12.10 considered as heaviest that 12.04.

Thanks

If your computer is old enough that it can't support PAE then running Ubuntu 12.10 even with a non-pae kernel you probably would find it too slow to use comfortably.

I would recommend Lubuntu 12.04, Lubuntu 12.10 has PAE kernel so wont work. However 12.04 was non PAE.
