Zorin os 16 core don't boot with USB drive

I get an error when I try to boot with USB drive.

The checksum is correct.
The USB was flashed with balenaEtcher, DD and Rufus in GPT.
That doesn't seem to be the problem.

So I tried on three different computers, one of them has Windows 10 installed and boots the Zorin 16 normally.
The others, which has Fedora 34 installed, I get these errors.

Invalid Image
Failed to read header: Unsupported
Failed to load image: Unsupported
start_image() returned Unsupported

What that means?
My hardware is unsupported?
Someone get the same errors?


On the troubled machine, once the installation errors out, can you try Boot repair?

sudo add-apt-repository -y ppa:yannubuntu/boot-repair

sudo apt-get update

sudo apt-get install -y boot-repair && boot-repair

Please reference here:

The live CD don't boot, what I mean is the grub menu do not appears, that is, it does not enter the live system and I can't try or install Zorin.

Note: The secute boot and fast boot already disable.

What machine are you installing on? Year, make and model?
I wonder if creating the Zorin Bootable with and booting with rEFInd may help you:

A post was split to a new topic: Zorin OS 16 Core cannot install boot EFI

Had the same issue last night, which was not what I was expecting after several
attempts to download the ISO image, kept failing.
I just assumed there was something wrong with the conversion to the bootable
image going to flash drive, or something with the download itself, so I downloaded another ISO this morning and will try again later...

I had the same problem as well i think the server was overloaded yesterday or something went wrong. The download link was saying not found. Ended up continuing the download later but the ISO seemed fine for me after downloading.

I already did this.
I downloaded last night and today.
This not the problem.

I tried this and that works.
Now I'm installing the Zorin, if all goes fine, this topic will be closed.

Did your machine use UEFI originally?

A post was split to a new topic: Zorin OS 16 Core install Failed to open EFI boot - invalid parameter

Yeah, I used.

Ok will try the link in the previous message. Have only used Zorin 15.3 for a week so hadnt put too many things yet. Wanted to be sure before i made any changes.

Try this, it's work for me when I tried to boot the live CD.

Can you let me know if the system still boots without issues

You mean the rEFInd?
yeah, it's boots normally.

It's appears in the boot menu, and not substitue your boot manager (GRUB).

So.... This didn't work for me, still getting this error. Luckily, I hopefully found the way to remove rEFInd off my Bios, because I can't even get to F2 or F12 with it on it. It boots straight into rEFInd and I when I use that to boot from USB, I get that error.... A little frustrated here... OK, more so pi55ed...lol

Please take not of this Update from ZorinGroup:

Gee, guess who owns a Dell....lol.
I had to reset the BIOS to remove refind, so glad that at least worked...

Aravisian, you're the Best... Thank You for this update.

How will we know when it's good to try again?

I'm having the same issue with my old custom PC:
ASRock Z97 anniversary edition
Intel i5 4460
AMD radeon R9 290
I can and have installed Zorin 16 core in legacy mode but my windows is installed in UEFI so I currently just have to use the boot menu to select an OS as grub cant accodidate legacy and UEFI at the same time I believe.
I will be reinstalling in UEFI mode when this problem is fixed as the response from the ZorinGroup has not worked for me.

That didn't work for me. Any other possibilities?
