How to remove countdown in grub menu (disable countdown) [duplicate]

  • 772

I have a dual boot ubuntu and windows 8. Ubuntu is default os to start up and countdown select the default os to boot If I don't change that before. When I order between ubuntu and windows 8 countdown automatically hide and then, I have to press enter to boot from any highlighted os without time limit.My question is: How can I disable countdown for always and I select which os starts up with using up/down arrow key myself and until I don't select and don't pressing enter, that freeze on grub menu. Any ideas would be my pleasure

Note: There is no /etc/default/grub file in my ubuntu.

Edit: I reinstalled grub (sudo apt-get --reinstall install grub2 grub-pc) and now i have a/etc/default/grub file but the countdown did not stop with this changes:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT="-1"
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

I delete double quote GRUB_TIMEOUT="-1" around -1 which is automatically added to it and save then running sudo update-grub I get the following warning:

Warning: Setting GRUB_TIMEOUT to a non-zero value when 
         GRUB_HIDDEN_TIMEOUT is set is no longer supporte

    To get grub file in /etc/default/grub

    sudo apt-get install grub2 grub-pc

    Then run

    sudo update-grub

    Now open /etc/default/grub using your favourite editor.

    (you may need sudo permissions!)

    And set this field to -1 to wait indefinitely!

    GRUB_TIMEOUT=-1

    You can try to comment out the following two lines to

    # GRUB_HIDDEN_TIMEOUT=0 
# GRUB_HIDDEN_TIMEOUT_QUIET=true

    Now again run

    sudo update-grub

    and you are done! Hope this helps!

  2. You can do this graphically with Grub-customizer, and the instructions for installing that program are located in the Ubuntu forums at http://ubuntuforums.org/showthread.php?t=1664134

    Please note that the instructions in the link are slightly dated - grub-customizer is now available in the standard Ubuntu repositories, and can be installed with the commend

    sudo apt install grub-customizer

  3. Perhaps you have an EFI system, and grub is on the EFI partition. Hopefully mounted for you under Files->computer->/boot/efi, on my system grub.cfg is in /boot/grub .

    No idea if the solutions posted so far would work for that.
