Hi and welcome to the forum.
Your forum profile indicates you have ZorinOS Lite.
Can you tell us, is it Z16.3 Lite or Z17.1 Core that you are attempting to install?
I see you checked the SHA256 of the .iso, so that is a good start. Do have a look at this pre-installation advice, particularly about disabling Secure Boot (BIOS) and Fast Start (Windows). Before you install
I wonder if you chose to include updates and additional drivers e.g. Nvidia as part of your install? If you did, try again with those two items unticked.
