Black screen problem after boot

Hello. I tried to install Zorin OS 18 Core. I downloaded the ISO file to a USB drive. I booted my computer from the USB and saw the screen with "Try" or "Install" options. I chose the first one. Zorin OS started, and there was a login screen. I selected "Live Session User," but then a black screen appeared on my monitor. I waited for 2–3 minutes, but it didn’t fix the problem, so I unplugged the computer and started my main operating system. How can I fix this black screen issue?

Welcome to the Forum!

A couple Questions:

  • Did You checked the Checksum of the ISO?
  • What Tool did You used to create the bootable USB Stick with Zotin on it?
  • Are Secure Boot and Fast Boot on BIOS disabled?
  • If Windows is still installed: Is Fast Start-Up in Windows disabled?
  • Is Your BIOS in UEFI or Legacy Mode?

Here are Instructions:

Did You checked in the Ventoy Settings when You have created the USB Stick that it is set to GPT and not MBR?

Then, I would suggest to disabled them.
