"File not found" at that point would suggest it can't find the kernel
file. The path here should be relative to the root of the partition
/boot is on, so if your /boot is its own partition then you should
either use "kernel /vmlinuz...." or (the more usual solution from what
I've seen) make sure there's a symlink:
ln -s . /boot/boot
