How do I change the boot order in Ubuntu?
You have Ubuntu 13.10 and Windows 7 installed and dual-booting but want to have Windows 7 moved to the top of the boot order list? How do you do this?
First install the Grub Customizer application which is a GUI interface that allows you to easily change the boot order. To download and install Grub Customizer, do the following:
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
Once you have the application installed, open it and take a look at the following links on how to use it. I was able to figure it out and I’m a Windows guy. Good luck!
