Not to ask for grub password
security;grub
I assume you are trying to set a password to edit GRUB but you need to boot without being asked for password.I think in addittion to your current configuration you need to edit /etc/grub.d/10_linux  and add the --unrestricted option.For a complete reference you can check this link in AskUbuntu I posted once, when I was stuck in the same situation.Update: Answering your second question about hitting e. For getting the grub menu you need to comment the GRUB_HIDDEN_TIMEOUT and GRUB_HIDDEN_TIMEOUT_QUIET parameters, I guess its a bug.
