I have a dual boot setup with Windows 10 and Ubuntu 15.04 on my laptop.

I want Ubuntu to be the default and auto starting and windows to boot only when selected.

Is that possible and how do I get it to work ?

Graphical Method

  1. Install StartUp-Manager
  2. Go to Boot Options >> Default Operating System
  3. Select your Linux version. Change the timeout number to a lower number if you want a speedier boot sequence.

Terminal Method

  1. Type cat /boot/grub/grub.cfg | grep menuentry . Note your Linux entry number (remember that entries start at 0. Thus if Linux is the 5th entry then your entry number is 4 for example).
  2. Edit /etc/default/grub by changing GRUB_DEFAULT from 0 to your noted Linux entry number.
  3. Type sudo update-grub to update your changes to the bootloader.

Good luck!
