Took me a minute of looking to figure it out....
Look at this line:
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
In yours, in the screenshot, you have a (") that shouldn't be there...
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`"
Please remove that (") symbol at the very end of the line so it is
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
and sudo update-grub and reboot and test...
Just noticed there is also a " after the =
Just wondering why there are so many mistakes in my file. I didn't do anything.
....
I removed the " but after update-grub I get the same answer.
I will restart now...
Neither of those should be there. It should look like:
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
didn't change anything and like I said I got the same output after grub update
sudo update-grub
Quelldatei `/etc/default/grub'
/usr/sbin/grub-mkconfig: 37: /etc/default/grub: Syntax error: EOF in backquote substitution
Do I need to get rid off these as well at the bottom line (see pic bellow)?
Starting to think of wiping Zorin of my ssd and start from scratch cause it seems more problems start to appear and I don't want to waste more of your time...
see... I can't get rid of that grub-customizer even with copy/paste a command to remove it...
Just not sure if it is easier for me to get rid of Zorin, keeping Windows 11 untouched and be able to boot into it, so everything is clean again (apart from Windows 
This might help:
However what did seem to work OK was going to the /etc/grub.d directory and moving everything with "proxy" in it's name to a separate (new) folder. Then I ran the commands you posted and it all seems to be fine now.
I checked my laptop with grub-customizer and indeed it has this -proxy suffixed files which are absent in my desktop without grub-customiser.
No, those are normal...
But I did just spot More Quotes.
This line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" acpi_backlight=vendor"
It also has too many quote marks. It should be only beginning and end looking like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
I assume that you did change these that I pointed out above?:
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
Sorry that I did not spot the additional quote mark earlier. I have no idea how your grub got riddled with so many of these...
Once you make the changes above...
sudo update-grub
Your error message confuses me. What is going on with your kernel?!
Please post the output of uname -r before you reboot to test the above...
yeah, I did everything you said and now the additional stuff.
looks like this now
and whoowhooo something new as a result
and uname -r
Ok, run:
sudo apt --fix-broken install
sudo apt remove --purge grub-customizer
I think it all worked fine. Didn't get any error...
Restarting computer...
I hope it works.
If not, you could try the solution I posted above.
it freakin worked!!! 
WOW!!
Thank you Guys so much!!
So the whole Grub (looks) is "based" on this file?
So now everything should be clear and clean again before I tried installing Budgie on to a stick 
For this... Recommend *ventoy* instead of trying to install to stick...
I think what has happened was that you have created a situation of triple booting by installing Budgie on the USB key. I only did dual-boot and never ventured out triple booting on the same system.
