All well up to the end of ... efi.bak
Then, after typing in the "Copy GRUB over" instructions: (several attempts at this as I had to make sure there were no mistakes):
cp: cannot stat '/mnt/esp/EFI/ubuntu/shimx64.efi': No such file or directory
hmmm
ls /mnt/esp/EFI
If that shows only Windows OS, I will recommend reinstalling Zorin OS (again) but this time, use the Something Else option.
Set /boot/efi as the mount point for /dev/sda1
Set / as the mount point for /dev/sda3 and format to ext4
At the bottom of the window for the Device for bootloader installation: - set to /dev/sda1
Then click Next > Install
I'm terribly sorry but I really don't understand any of this. It is now 12.35 a.m. UK time and it's doing my head in... I think I'm going to have to go to bed and return to this tomorrow. Thank you for your help so far - I really appreciate all the time and effort you are putting in to help me! - but if you could rephrase your last comment it might help - this computer language is really foreign to me and I'm finding it very difficult to grasp. I do hope you understand. See you tomorrow.
I really do: We all experience it.
We look up a guide on the internet and it gives some "self evident" answer that the author assumes you already know.
Tomorrow, after you have had time to rest, we can take this (With me or another helper) one step at a time.
It's not difficult - Just Unfamiliar To You.

This site may also help you:
Hi, I am back online. I see there are now 2 new sites to look at for help but I don't want to get confused with too many different advices so for now, I'll wait to see if you are around, Aravisian. Thanks. (Both those sites say I should enable Secure Boot but I thought it was vital that this was DISabled...)
Both of those also do something I did above: Presume that the EFI file was created.
Currently, we are taking a step back to see whether or not it was created.
In your LiveUSB session, opening a terminal, run
ls /mnt/esp/EFI
Remember that ls is list and that is followed by the path to the directory you want to list the contents of.
When you run that, it will list the contents of the bootloader EFI directory.
If there is no Ubuntu file there - then one was never created. If there is one, that means the firmware of the Acer computer is ignoring it as "untrusted."
That's great - thanks. Ran it:
Boot Microsoft OEM ubuntu
So it looks as if it's there.

Good, that makes things easier.
The next step:
sudo mount /dev/sda1 /mnt/esp
Check your files:
ls /mnt/esp/EFI/ubuntu
This should show
shimx64.efi
grubx64.efi
If you see shimx64.efi, you can move to the next step:
sudo cp /mnt/esp/EFI/ubuntu/shimx64.efi \ /mnt/esp/EFI/Microsoft/Boot/bootmgfw.efi
Typed in your first line. Result:
mount: /mnt/esp: /dev/sda1 already mounted on /mnt/esp.
dmesg(1) may have more information after failed mount system call.
That is fine - already mounted: Can move to the next step
It just says:
grubx64.efi
I think this now clarifies why those other sites wanted to enable Secure Boot.
That would allow the shim file to be seen. Since you do not have one, it would not help you...
Run
sudo cp /mnt/esp/EFI/ubuntu/grubx64.efi \ /mnt/esp/EFI/Microsoft/Boot/bootmgfw.efi
I'm encountering a really stupid problem with that acer computer! When I press the backslash key I am getting < instead. I cannot find the backslash key anywhere!!
Maybe AltGr+ß or AltGr+< will make backslash on your layout?
Too bad you cannot just copy and paste the line over...
The only way I can get < is by pressing the backslash key. I don't have the other key you mention. That Acer laptop is my old laptop that I gave my hubby and I used to run Windows 10 on it and I don't remember anything peculiar about the keyboard when I was using it. It seems as if Linux thinks it's a US keyboard or something - I've tried googling it on this laptop but not getting anywhere. Apparently the US keyboard doesn't have a backslash key. I agree - it would be great if I could just copy and paste the line over.
Solved it!! I clicked on a button in the dash and the keyboard was set to US. I changed it to UK and the backslash miraculously reappeared. Will now go ahead and type in the line you suggested. Give me a mo.

Maybe use the Zorin Connect app or another USB to put it in a text file?
Typed that and got this result:
cp: cannot create regular file ' /mnt/esp/EFI/Microsoft/Boot/bootmgfw.efi': No such file or directory
