Could you provide

$ ls /boot
$ ls /dev/.initramfs/live/
$ ls /dev/.initramfs/live/isolinux/

I just realized that I provided the wrong path, it should be:

$ ln -s /dev/.initramfs/live/isolinux/vmlinuz0 /boot/vmlinuz-$(uname -r)

Please remove the old link in /boot and try to link it like given above.
