Can't disable the GRUB menu

Fri Oct 28, 2016 12:56 pm

I have been running Linux17 and 18 for 5 or 6 months using BIBM. I have multiple OS's installed (they are all primary partitions as I have not limited primary partitions) but all are hidden in the Linux boot menu within BIBM. All of sudden, after running into a hiccup I had to reinstall Linux 18 and the GRUB menu popped up. It was never there before. I have tried everything I can find on Google to hide this darn thing with no avail.
Is there something in BIBM that will not let me hide the GRUB menu?
Any other tricks the Linux community doesn't know about that won't let me hide it?
Thanks,
Bob S

What shows in the GRUB menu? Anything there that shouldn't be? My guess would be it added another OS entry and triggered a timeout value.

Re: Can't disable the GRUB menu

The menu has a box around it and inside the box is:
Linux Mint 18 Cinnamon 64-bit
Advanced options for Linux Mint 18 Cinnamon 64-bit
Memory test (memtest 86+)
Memory test (memtest 86+, serial console 115200)

At the bottom outside the box is:
Use the (up arrow) and (down arrow) keys to select which entry is highlighted
Press enter to boot the selected OS, 'e' to edit the commands before booting, or 'c' for command line
The highlighted entry will be executed automatically in 30 seconds.

The 30 seconds count down. It seems to be a normal GRUB2 menu

Thanks,

Bob,

I saw that screen with Mint 18 KDE but I was using a UEFI system and booting Mint with EasyUEFI. I got rid of the screen by editing /etc/default/grub. The Timeout was changed to 0.1

I also removed the 0 (zero) from GRUB_HIDDEN_TIMEOUT=0 so it read GRUB_HIDDEN_TIMEOUT=

Then...
sudo update-grub

No more screen.

Thanks for your help, Brian, but I have changed so many things in GRUB that didn't work. I had NOT tried the GRUB_HIDDEN_TIMEOUT=(blank), tho. I tried it and still got the menu.
Here is my GRUB 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=
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
GRUB_DISABLE_OS_PROBER=true

***************************************************************
Maybe something else is getting me.

You did note:

If you change this file, run 'update-grub' afterwards to update

It may also be helpful to see the actual grub.cfg file. There may be other commands being inserted that override the options you've set. Some of the automated sections can set a timeout depending on what they find, for example.

Yes, I did note 'update-grub'. And yes, there may be something in my grug.cfg file so here it is:

I have tried setting all of these time delays to 0 with no avail as I'm sure grub-mkconfig is changing them. I have NOT tried deleting the 'menuentry' items (read this in Google somewhere) as I am too much of a newbie to Linux to try anything too exotic.

Thanks,

Re: Can't disable the GRUB menu

Mon Oct 31, 2016 12:20 pm

Bob,

This worked for me. I needed both edits...


GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=0.1
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""


This doesn't work. I still see the menu...

GRUB_TIMEOUT=0

0.1 works


This line wasn't present...

GRUB_DISABLE_OS_PROBER=true

Re: Can't disable the GRUB menu

Mon Oct 31, 2016 2:58 pm

Brian'
I changed GRUB_TIMEOUT=o to 0.1 and deleted the GRUB_DISABLE_OS_PROBER=true line ( I got this from another Google input) and I still get the darn menu. I have tried 0.0 and 0.1 in both of the timeouts with no avail. I did try your suggestion, tho just in case.
Thanks for you assistance. If you think of anything else, please let me know. I'm getting ready to just reinstall the whole OS all over. I really don't want to go back to Windows 10.
