I can't install Zorin 15.3 Lite 32 bits

I downloaded the latest version of Zorin 17 Core, used Ruffus and after rebooting the PC I was able to install it on my Notebook via USB.

The problem was that my processor is 32 bits, so asking in the forum https://forum.zorin.com/t/zorin-os-uefi-shell-startup-problem/37542 I found this page https://sourceforge.net/projects/zorin-os/files/ where I downloaded the Zorin 15.3 Lite 32 bits version.
The problem is that I repeat the process with Ruffus, as I did before, I connect the USB to the notebook, I change the boot options, but the pc boots with the operating system as if nothing (in my case I am with Debian 12.5).
I tried other versions and the same, I try again with the Zorin 17 iso image and it works, the problem is with the iso images of previous versions. What can I do?

Zorin 15.3 is no longer supported and at end of life. Ubuntu no longer develops 32-bit software. Since Zorin 16 and 17 are all based on Ubuntu which is 64-bit and they need a 64-bit processor.

Your best bet is to use a Debian based operating system. Debian-proper is a solid choice but not the easiest. There are many derivatives like MX Linux, antiX, and LMDE that make it easier to use Debian. Search Distrowatch.com to see if there are other 32-bit choices. Debian announce recently they will stop supporting 32-bit hardware in the future but I don’t remember when that will happen.
