How to hide grub2 menu?

Question

I need some help, I screwed up while trying to auto-mount on boot my USB external HDD, something went wrong and it doesn't boot to Ubuntu.

I installed this https://help.ubuntu.com/community/Boot-Repair and I ran it to repair the boot, and now I have a boot menu.

The menu shows down booting and I don't need it so how do I remove it?

Answer 1

You should use the following steps to hide GRUB (it is still installed)

1. Run this command in terminal

   sudo -H gedit /etc/default/grub
   

2. Set these lines (create them if they don't exist), doesn't have to be this order

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

3. Save then close the file

4. Run this command in terminal

   sudo update-grub
   

Answer 2

actually I was having this menu already configured...

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

I did it by removing word splash from second last line :)

cool right?
