How do I hide grub

Question

I have my grub menu showing on boot up when it should not be. I have tried the following but it still doesn't work. For reference here is the contents of the grub.cfg file:

# 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=10
GRUB_DISTRIBUTOR=`lsb_release -d 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"`

Did you run update-grub? – Organic Marble Mar 16 '16 at 18:19 — Organic Marble, Mar 16 '16 at 18:19

(Something to remember: I just want to clarify that the 'grub' file i am telling you to edit is the one found in /etc/default. There is a stark difference between the two that you can see at the start of the files. The 'grub.cfg' file found in /boot/grub starts like this: DO NOT EDIT THIS FILE. The grub I'm talking about here starts like this: If you change this file, run 'update-grub' afterwards to update /boot/grub/grub.cfg. So, you're technically editing the 'grub.cfg' file, but not directly.)

Ok, so you want the GRUB bootloader to not show up, right? There is a way!

Press Alt + F2 then type:

gksu nautilus

Using the automatically opened file explorer, open /etc/default/grub.txt

# 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=10
GRUB_DISTRIBUTOR=`lsb_release -d 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"
boot

So go back to 'grub' and change the number of GRUB_HIDDEN_TIMEOUT to 1, change the value of the line right below it to false, then change GRUB_TIMEOUT's value to 1. After that it will look like this:

# 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=1
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=1
GRUB_DISTRIBUTOR=`lsb_release -d 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"

(if you are unable to save the file, then press Alt + F2 and type gksu gedit and open the file from there.

Save and close the file, press Ctrl + Alt + T, then run the command:

sudo update-grub

And, when its finished, restart your computer, and see what has changed!

Hope you liked it! ;)

You should never edit /boot/grub.cfg directly as your changes will be discarded as soon as you run update-grub, which you also said to do, so the net effect of your instructions is null. — psusi, Mar 16 '16 at 23:00
I meant to say the /etc/default/grub.txt file. Again, even though you are not touching 'grub.cfg', you still are technically editing it. — skybldev, Mar 18 '16 at 15:07

Update /etc/default/grub to match this, and run sudo grub-mkconfig -o /boot/grub/grub.cfg.

GRUB_DEFAULT=0
GRUB_TIMEOUT=0
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="" 
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_GFXMODE=auto
GRUB_GFXPAYLOAD_LINUX=keep
