I've had Ubuntu on my laptop for the longest of time and I've loved it ever since. But then I decided to get Windows 10, and completely forgot about dual booting, however, after getting Windows 10, I dual booted it with Ubuntu again, now for some reason, it always boots to Ubuntu and never even gives me a choice, I need help, this is frustrating :/.

    Check with Gparted how do the partitions look and edit the post with that info. – M. Becerra Nov 16 '16 at 18:14
  • If you are using Windows 10, you must make sure fast start up or always on hibernation is off. And/or turn off all hibernation settings including low battery. Only then can grub2's os-prober find the Windows boot files to know what partition to boot Windows from. And Windows may turn fast start back on with updates. http://askubuntu.com/questions/145902/unable-to-mount-windows-ntfs-filesystem-due-to-hibernation Grub will not boot hibernated Windows. You may have to temporarily install a Windows boot loader to boot Windows to turn off fast start up. Then reinstall grub & run sudo update-grub – oldfred Nov 16 '16 at 19:12

Four things to do:

  1. 'sudo nano /etc/default/grub' to edit the grub configuration
  2. Find the line 'GRUB_DISABLE_OS_PROBER=true' and change the 'true' to 'false'
  3. Ctrl + x to save and Y
  4. 'sudo update-grub && sudo reboot'

All the best

I had the same problem. I tried boot-repair, it worked for me.
