I have a pc with Windows 10 and Ubuntu 16.04, set as dual-boot. The pc came with Win10 and I installed Ubuntu on it recently.
Everything works ok, but when booting the computer I have only 10 seconds to select an option, if I don't do anything within those 10 seconds Ubuntu starts automatically. I usually only use Windows so I prefer that to act as primary OS.
Is it possible to either set Windows as the default selected option, or disable the 10-secs timer?
Boot into Ubuntu and install an app called Grub Customizer. Open a Terminal window and type:
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
(Press Enter after each line of text).
Go to the main menu and start Grub Customizer. You can change default timing (those 10 secs) in the General Settings tab.
Alternatively, you can do similar actions in Windows by installing GRUB2Win application.
Just make sure you don't uninstall GRUB as Ubuntu needs it in order to boot.
Yes, it is possible and not very difficult. You can use a tool named Grub Customizer. To install that write:
sudo apt-get install grub-customizer
I'm using an answer from another part of askubuntu.com, more information is provided there.
Another way is to edit the grub2 configuration file /etc/default/grub directly and run update-grub after that.
