Hide GRUB menu in Linux Mint 17.1

I have recently update my laptop's OS to Linux Min 17.1. Everything went smooth. I have used mintUpdate applet. Very easy and good solution for lazy people like me.

I have noticed only one problem, after reboot GRUB menu was shown (which didn't happened in 17.0). The old method used for Mint 17.0 didn't work.
After some digging I have found solution.


In console just execute: 

 sudo -H gedit /etc/default/grub  

Find and edit below lines:

 GRUB_DEFAULT=0  
 GRUB_HIDDEN_TIMEOUT=10  
 GRUB_HIDDEN_TIMEOUT_QUIET=true  
 GRUB_TIMEOUT=10  

Change default values to this one:

 GRUB_HIDDEN_TIMEOUT=0.0
 GRUB_HIDDEN_TIMEOUT_QUIET=true  
 GRUB_TIMEOUT=0.0  

and at the end of line add:

 GRUB_TIMEOUT_STYLE=hidden  

After changes it should look like this:

 GRUB_HIDDEN_TIMEOUT=0.0  
 GRUB_HIDDEN_TIMEOUT_QUIET=true  
 GRUB_TIMEOUT=0.0  
 GRUB_TIMEOUT_STYLE=hidden   

To finish just save changes in file and execute:

 sudo update-grub2  

After reboot GRUB menu won't show.
