I'd set OS Type to other OS, set secure boot mode to standard, apply the changes and boot into Zorin. Then check the secure boot state with
"sudo mokutil --sb-state".
now it say: SecureBoot disabled.

Then you can install the nvidia drivers.
sudo apt remove --purge '^nvidia-.*'
sudo apt install nvidia-driver-575 nvidia-dkms-575
Thank you, I’ll let you know if works.
First remove old nvidia drivers. I added the commands above.
Literally same thing 
I didn’t do the sudo apt install nvidia-driver-575 nvidia-dkms-575 part because I did not see that part.
Without this command no nvidia driver will be installed and nouveau driver is used. Or did you select an nvidia driver at Additional drivers?
So try it again. After that reboot.
Welp, now I’m stuck to to that because I’ve tried switching
back X org server and did not work. Thanks for your help!
Yes I did bruh.
Whatever, I’m done with this.
Thanks for your help and I’m now going to bed because I AM tired of this non-sense.

You literally DID. NOT. told me THAT PART and now I’m stuck with this STUPID SCREEN.
It can be very frustrating needing something to work and it not working.
However, it was quite early in this thread that another member pointed out the need to install the Nvidia Drivers.
Three people have given these instructions, so far.
Forpli repeated the instructions to you.
And logic follows that if you do not install the drivers; then the uninstalled drivers cannot be used.
You are not stuck with the screen. You can use the recovery mode if needed; though it is not needed because you can use the desktop, just at a lower resolution.
Or use the TTY (teminal) accessible with ctrl+alt+F5 and Exit it with ctl+alt+F7
Once rested, calm and ready, follow the instructions provided instead of yelling at the people who took time out of their day for free to help you.

So I need to do the command right now like he said while I’m stuck on that thing? Nope, that won’t work out.
Did and say “failed to fetch whatever is it”
So that’s great 
I’m still stuck with this screen.
Also WIFI disappeared???!?? So I can’t download anything, wow.
The two things that will help you the most at this point are:
- Following the provided instructions and reading them in full
- Relaying errors you see and being clear about what you see on your screen and what actions you have taken.
The helpers here are limited to what information you relay. This is true of any O.S. and any helpdesk. "I did" and "That didn't work" are nowhere near enough information for a helpdesk to determine what went wrong or how to correct it.
And following the instructions are the most critical step toward success. A computer cannot think, heal or self-correct. It follows commands exactly and a typo or misplaced line in a command is all it takes to halt a process.
What you can do:
- Relay your hardware specifications including Wifi and Display. You can get this information from:
sudo lshw -C network
That will tell us what wifi you are using and what driver
- Which kernel you are on:
uname -r
- Your graphics information:
sudo lshw -C video
To get unstuck from the screen you are stuck on, at boot, enter the grub menu either by tapping esc or tab and select Zorin on 6.8 (recovery)
The (recovery) portion shows you will enter the recovery menu. From here, you can arrow key down to enable networking.
Once that is done, back up to the recovery menu and arrow key down to Drop to root prompt.
From here, you can enter the commands needed to get drivers installed.
Without you taking these steps and putting your genuine effort into your own machine and communication: Our hands are tied.
Nevermind but I only see 17.3 Recovery mode
That is the path to the Recovery Menu.
