I am unable to install the zorin operating system and my pc keeps rebooting
Hi Jon. I'm sorry you're having issues. You mind telling us where you downloaded your iso from, did you check the sha256 hash to ensure it wasn't corrupt, which version are you attempting to install, what kind of machine are you installing to, does it have nvme drives, ssd or hdd, do you know what video card is installed, can you boot to the live image?
Just a few things that will help us assist you.
Did you perform the steps in the above link
