Problem you have encountered: Unable to set up grub password in GCE instance.

What you expected to happen:Accessing by Serial Console to the instance, be able to introduce grub password. But instance was not even asking for that.


Steps to reproduce:
-Create a instance
- Create password by typing $ grub-mkpasswd-pbkdf2 inside that instance
- Copy the whole generated code
- Edit the file /etc/grub.d/00_header
- Add [1] to the end of the file
- Update grub with: $update-grub (run as sudo)
- Reboot the instance

(Here you should be prompt to enter user and password, but it's not happening)
