Can somebody tell me how can i disable the menu that comes up when i boot up my laptop? Thank you!
Assuming you mean, make it so that the menu goes straight on through without prompting…
sudo nano /etc/default/grub sudo grub-mkconfig -o /boot/grub/grub.cfg
Beware that this means that if you have a kernel misbehaving that it will be difiicult to stop the process and choose another kernel to boot to. You will find that holding SHIFT at restart should then give you the menu back.
This is exactly what does not work for me. No matter how long I hold SHIFT, it boots through completely until the login.
On some machines, you press the ESC key instead of Shift.
That is what it is on my system.
