Unable To Install Grub error

Hello, im currently new to this forum and linux altogether and i want to dual boot zorin os along side my windows 10 but im having a problem installing it, ive tried many ways to fix this issue through previous forums ive read(eg. Using boot repair) but im still getting the same error all the time. So I've came here as a last resort and post a forum.
I use a Lenovo IdeaPad 320 with UEFI
And here is my pastebin:
https://paste.ubuntu.com/p/YNbNRZYqpW/

Im terribly sorry in advance if my explanation is bad and i will be more than happy to clarify things to solve this problem.

Welcome to the Forum!

Let me ask some Questions:
Is Secure Boot and Fast Boot in the BIOS turned off? If no, try it with turned off.
Is Fast start Up in Windows deactivated?
Did You checked the Chemsum of the Zorin ISO?
What Program did you used for create the bootable USB Stick?

Sorry for the late reply, but yes, I've turned off secure boot and fast boot alongside fast startup. Ive used rufus to create my bootable usb stick. But i dont really know how to check the Chemsum. Could you please explain it and how it works?

See this:

Basically with Quickhash you select SHA256 test, then drag the .iso file into the app window, then cut-and-past the Zorin published SHA256 checksum to the app. It will then check and confirm if checksum is correct (or not).

i had this issue lately and i removed my ethernet hardwire and the install completed.not sure if this pertains to you but that was my finding. with it connected i found it left me at grub and searching around (hd0 ,1) kernel could not be found.
:sweat_smile:

The checksum seems to be alright.

(Terribly sorry for the late response)

We cannot view your Ubuntu pastebin. Needs account and sign-in, so forget that.

Can you answer:

Have you tried a different installer program and/or different USB?

I can't read the pastebin because I don't have an Ubuntu account to login, but there's always a small chance that your device has 32bit UEFI even if it has a 64bit CPU. Less likely if your Windows install is 64bit, though. To check, try installing a 32bit linux like LMDE.

If that works, you can then install Zorin by manually doing the partitions and selecting the exact EFI partition that LMDE setup for boot.

Note: the above guide tells you to pick a "device" (entire drive) for the bootloader, but that's because it's talking you through the first linux OS being installed alongside Windows. If you already have a linux dual-boot installation, you should pick the actual EFI partition specifically. At least, that worked for me.

Thats an interesting solution, but unfortunately it did not work. When i try to instal LMDE 32bit, it gives me an error allong the lines of
"efi: No EFI runtime due to 32/64-bit mismatch with kernel"
And after a little bit of research the solution for that is using a 64bit version of it, so i guess im trying that in hopes it will work.

I've used rufus as my first, but tried balena etcher to install linux mint
(to test the previous reply's solution)
I dont really have an extra flash drive laying around but i will check if there are any cheap usb's i can buy (around 32gb), I'll update you guys if there are any changes.

When you used Rufus, did you have chosen at the Partition Sheme GPT?

Yes, I've also used this tutorial on YouTube if you have any more questions about the installation.

If you can download the text from your first link then submit it here and then use the link it generates. Personally I prefer Ventoy as a USB installer. You can use GtkHash for checksums, it is OS agnostic.

I know this Video. So, You did a manual Partition like in the Video? If yes, I would suggest to go a different Way. When You can choose in the Zorin Installer the Installation Type, don't choose the ''Something else'' Option like shown in the Video. Instead use the Option ''Install Zorin OS alongside Windows''.

When You choose this, You don't need to manually partition Your Driver. You don't even need to prepare your Drive with free Disc-Space. When You choose this, You will see a Toggle with that You can adjust how many Disc Space You want to use and the Rest makes the Installer automatically.

Well it fixed it, taken from your advice i created another partition and made it an EFI partition (just like the windows bootloader) and installed grub there. Initially, i still got the same error but when i used the boot repair and went to the BIOS, made the "ubuntu" boot my first boot, and somehow. It worked, i dont know how but it did, sorry if my explanation is terrible and i would like for you guys to make a more clear explanation with procedure from you guys so i can call it a solution for this forum.

(Also heres the vid where I've followed the installation process)

(Sorry for late reply, the schoolworks are killing me)
