How do I reduce the number of wait seconds grub waits before launching ubuntu 10.10?

Run this in your terminal:

sudo -H gedit /etc/default/grub

This will open up the grub configuration file. Look a line similar to GRUB_TIMEOUT=0 (Here I have set the grub time to 0). Change the number to 2 or whatever time you desire (in seconds).

Save the file and run

sudo update-grub

Found this in a related post: You can install a program called StartUp-Manager.

The package is called startupmanager. You can search for this in the Ubuntu Software Centre or Synaptic or run sudo apt-get install startupmanager in a terminal.

After it's installed, it is available in the System > Administration menu options.

You can change it in /etc/default/grub and then run update-grub.
