Does the processor have ARM architecture? If yes, Zorin doesn't support that. You could install Zorin in a virtual machine or use a distribution that supports ARM architecture.
A user tried to install Zorin the following way but I wouldn't recommend that if you are not experienced and he only did it in a virtual machine, so it is not clear if it really would work on bare metal:
It should be possible by installing ubuntu in arm architecture first (there is no LTS build for arm desktop at the moment, only a daily build for desktop 24.04.3 or a LTS arm build for ubuntu server), adding the zorin ppa and installing zorin desktop.
sudo add-apt-repository ppa:zorinos/stable
sudo apt update
sudo apt install zorin-os-desktop
Then reboot.
