How to disable boot menu?

Question

Sometimes, when I reboot the dirty way, I get a menu (black screen, grey letters) .

This is asking to choose what/how I want to launch Ubuntu (very sorry I dont remind which modes).

How is it possible to disable it ? cause the computer has no screen and I dont want boot to be stopped by this screen.

Simple solution: Do not hard reboot. Advanced solution: see linked question above. — Byte Commander, Sep 14 '15 at 09:59
@ByteCommander : thank you but... without screen, users do hard reboot to shut down. Unless a better way is possible (w/o screen) ? — 3pic, Sep 14 '15 at 10:02
You have a keyboard? I guess without monitor it's a server release without GUI. Can't you configure it to shutdown if you only touch the power button (ACPI settings or something like that) instead of hard-shutdown? Or you could at least use the magic kernel commands (ALT+SYSRQ+R, then +E, +I, +S, +U and +B, waiting a short time for each command to complete.) — Byte Commander, Sep 14 '15 at 10:09
Another possibility is to remote login (I use PuTTY for that) and to start the command reboot — Marc Vanhoomissen, Sep 14 '15 at 10:37
no keyboard, no screen, no login, ... nothing but the on/off button. — 3pic, Sep 14 '15 at 12:03
I guess there is at least a LAN connection, otherwise I do not understand what your PC can do nor how you can control/manage it. If you have a LAN connection, then it must be possible to remotely log on to that machine. — Marc Vanhoomissen, Sep 14 '15 at 13:05

You need to change the grub boot settings..

sudo -H gedit /etc/default/grub

you need to change this line:

GRUB_HIDDEN_TIMEOUT_QUIET=false

to

GRUB_HIDDEN_TIMEOUT_QUIET=true

save configuration file and update grub:

sudo update-grub

There are also some grub setting applications that can help you with this using a gui.
