[Solved] show grub when booting still possible?

Post by catch22 »

Is it possible somehow to have GRUB show up at boot?
I followed this post viewtopic.php?t=55370 to arrange it, but it didn't change anything.
My guess is it doesn't work because Mint now has the extra guest-account option when booting, instead of the one user?

One of the problems with the thread you link is that there was a bit of back-and-forth over what exactly to do.

Instead, let's start from scratch. Try this:

1. Open terminal. Backup grub config file: sudo cp /etc/default/grub /etc/default/grub-default.

2. Open the original config file: gksudo xed /etc/default/grub. Comment out (place # in front of) line GRUB_HIDDEN_TIMEOUT=0; change GRUB_TIMEOUT to 3. You can use a longer timeout, e.g., 10 seconds, but 3 is plenty for a single boot machine. Save. Quit xed.

Note: If you're using KDE, the command to open the config file is kdesudo kate etc/default/grub.

3. Run sudo update-grub. Restart to test.

To revert, reopen file in text editor and reverse edits. Or, delete the modified grub config file, then rename saved copy of the original to its original name: sudo mv /etc/default/grub-default /etc/default/grub (move in same folder = change filename).

Thanks, but it's not working.
I had also tried the same with the line

Code: Select all

GRUB_GFXMODE=640x480
uncommented, as was suggested in the other post.
Now without uncommenting that line it changes nothing.

Are you dual-booting ? IOW, are you changing the grub files on the system which controls the boot?
Please edit your original post title to include [SOLVED] if/when it is solved!
Your data and OS are backed up....right?

To clarify:
In /etc/default/grub make sure that GRUB_TIMEOUT=3
Then you have to place a # in front of the line that says GRUB_HIDDEN_TIMEOUT=0 - so that it looks like this
#GRUB_HIDDEN_TIMEOUT=0
In order for that change to take effect, you have to run

Code: Select all

sudo update-grub


One additional step you can take is to add this line:
GRUB_TIMEOUT_STYLE="menu"

If that does not work, post the contents of /etc/default/grub

Code: Select all

cat /etc/default/grub

Nope, only Mint is on the machine.

had to be #commented :-)
