Could not find linux data

[Salman17546]

After I solved the ldlinux.c32 error I got this error. I wanted to confirm a few things. The kernel path in the config file is /vmlinuz. Should I change it to my kernel path which is /boot/vmlinuz-6.8.0-52-generic
When I do this the error occurs of cannot find linux data and without this there is an error of no kernel at /vmlinuz.
Does this have to do something with aufs and overlayfs? Because my kernel supports overlayfs as I saw in the config of my kernel but there was no name of aufs in there. And I searched the previous issues to find that kernel above 5.0 doesn't support aufs. So how should I change my scripts to support overlayfs and not aufs. I tried making ISO from linux-live-overlay repo but that was a failure as well. On that I encountered the error of not finding the kernel...
@Tomas-M help needed kindly go through my issue once....
