UPDATE: It seems to have been fixed now, I am no longer getting the Grub menu, please mark this as closed.

I have Ubuntu 12.10 installed with full disk encryption (fresh install), the issue is that the GRUB menu is always displayed, I am not able to set the timeout to 0 and default it to Ubuntu. I only have one OS installed, there is no need for the GRUB menu, also there is no timer on the menu, i.e its displayed forever until I select Ubuntu. I tried updating the GRUB config /etc/default/grub to set the timeout to 0, but nothing works :(

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=0

Did you run sudo update-grub after you edited the /etc/default/grub file? The changes won't have any effect unless you do that.

Yes,, I did :-) –  asp Oct 23 '12 at 19:17
    
Okay :-) Do you think you could post the content of your /boot/grub/grub.cfg? –  carestad Oct 23 '12 at 21:52
    
Added it to the original post, please take a look. –  asp Oct 24 '12 at 7:54

maybe grub customizer will do, try and manage settings with admin rights

  • sudo add-apt-repository ppa:danielrichter2007/grub-customizer && sudo apt-get update && sudo apt-get install grub-customizer

    sudo grub-customizer
