I get this feeling a lot... trying to help users on this forum...
Can you try booting the Installer LiveUSB, but at the grub where it asks if you want to "try or install Zorin" tap the e key to enter the grub editor.
You should see that option listed at the bottom of the Grub Menu...
After tapping the e key, scan the page looking for "quiet splash"
Once you find it, add the grub parameter pci=noaer to it so that it looks exactly like: "quiet splash pci=noaer"
Exit the editor and continue the boot... see what happens...
Repeat the installation procedure, including the e, to open editor, the noaer parameter.
Once you get to the screen that says,
"Install Zorin alongside" etc... you should see a last option below: "Something Else."
Select Something else.
This will open the partition manager. Once at that point, can you take a photo of the screen and post it here?
arrow key down and then over to "quiet splash" and add the parameter: "quiet splash pci=noaer"
tap ctrl+x to exit, then the y key to say yes to save, then the enter key.
The terminal will revert to normal. That will make that grub parameter permanent.
Reboot and test...
No downsides to performance, no. It merely quiets the error reporting, since the error is corrected (as you can see in your screenshots.)
However... You may prefer to use pci=nommconf - as this disables the PCI memory mapping. This one can potentially cause a loss of performance if the computer is left running for a time, though. For some it is several days... for others a matter of hours.
So, I usually aim for the noaer.
Ok, thank for the explanation. I update the system and see after that. Errors still here, don't mind for now.
Also I'm having issues when rebooting, it stays on boot logo and nothing, I have to force shutdown.
There are many things that can cause that... it would be best to start a new thread on that issue.
Possible causes can be MEI module
Nvidia Graphics
The EFI boot...
Solutions may be using a different Kernel. Blacklisting the MEI module. Or using the noefi grub parameter...
