System boot error : invalid magic number

[maitredede]

Hi,
I am using ventoy 1.0.20, on a physical hard drive.
When I try to UEFI boot debian 10.5 (live+gnome), I choose the iso, then I have the grub boot menu, select default entry, and I have these errors :

error: invalid magic number.
error: you need to load the kernel first.

Press any key to continue...

I am still searching for more information on how to fix this (even with a bios config...), but still no luck.

Does anyone have any idea ?

1. Only debian 10.5 has this error? Other iso files OK?
2. Please make a checksum of the ISO file to make sure that it is not corrupted
3. Please retry with the latest Ventoy version

I have the same.

ubuntu-21.04-desktop-amd64.iso and ventoy 1.0.53

[ventoy]

This is an old issue. I will close it now.
If you still have problem with latest Ventoy release, you can reopen the issue.

Same problem, 1.1.0.64 release, trying bodhi linux, but no tried other images with no success.

Ventoy-1.070:

debian-live-11.2.0-amd64-kde+nonfree.iso (includes microcode for non-free hardware) does not work, while debian-live-11.2.0-amd64-kde+nonfree.iso works

No problems with ubuntu (kubuntu 20.04/21.10, neon-user, ubuntu 20.04/21.10)

Q: can this issue be reopened?
@abuGit did you do a checksum of it from in Ventoy (press M)?

[abuGit]

Yes; I did a md5sum check on the usb device. The strange thing is that debian-live-11.2.0-amd64-kde+nonfree.iso is the only iso which dont work (and I use many ~ 12).

Here the link of the iso:
debian-live-11.2_nonfree.iso

Ventoy version 1.0.70
Same problem, with isos of:
Debian, Slackware, Zorin OS, Kubuntu. Linux Mint

Did you press m when booted to Ventoy to check the hash value of all of the ISOs and check matches the published values?
Is the memory of your computer reliable (perform a memory test).

The hash values changed when checking in ventoy with the built in tool, but the hash value of the iso matched the published one when I downloaded it (Tested with latest Ubuntu iso). My computer's memory is definitely reliable.

[steve6375]

Check the hash value of the files on the usb drive under Windows or Linux
If bad then usb file is corrupt.
If good then usb I/o reads may be the problem.
Report back which it is

[david-0609]

Checked, the hash of the iso file is still correct when first pasting the iso into the ventoy usb, I'll check if it changes after I try and boot it and report back.

Using m in Ventoy will use bios usb driver, using windows or Linux will use OS usb driver. That is why you need to check same file on usb drive using both m in Ventoy and using an os. Do not overwrite the file until you check with both methods.

Interestingly, some isos work and some don't for example, Fedora KDE live iso worked but Ubuntu 21 did not. I currently have 2 isos on my ventoy USB, Ubuntu and Fedora, the sha256 of the Ubuntu image did change, I did not check the Fedora iso
