1/ I am not a Ubuntu user. 2/ I am using dual boot Windows 10 and Remix OS 3.0 on my Dell xps 9350. On the dual boot option with GNU Grub there is the time counting down, which is 30seconds - too long for me. 3/ So anyone please time me how to adjust this time out, for example, to 5 seconds.

Thanks a lot !

Simply press Enter to abort the countdown and start the highlighted option immediately.

From within Ubuntu, you can change the countdown timer value by opening the terminal with Ctrl+Alt+T and then typing:

gksu gedit /etc/default/grub

to edit the configuration file.

Search for the line:


and change it to:


Then save the configuration file and exit the editor.

Next you need to compile the configuration file with:

sudo update-grub

then type exit to close the terminal.

When you boot again there will be a 5 second countdown instead of 30 seconds.
