I have installed Ubuntu 20.04 in my dell 5567 laptop and after installing it is just showing a black screen when I select Ubuntu in the GRUB menu. I have noticed some errors while restarting the system after installation. The errors are showing that hardware error and also firmware bug : ACPI region does not cover the entire command.

When I choose Try Ubuntu, it is opening and I can use Ubuntu like that. Why is it not opening after I installed the OS?
