[Marcofras]

Im installing new os no multilib amd64 and grub-mkconfig no prompt the lines with directory of vmlinuz i have in boot directory.
I installed os-prober too with mount and /etc/default/grub line.

To be able to help you, we would need a lot more information, in particular what you have done. Have a look at this thread:

Here @nxe9 has documented all his steps (in 3rd post). This enabled us to narrow down the problem.

If there is a problem with your manually configured kernel, please read the articles I have given.
