I have Ubuntu 14.04.1 dual booted with Windows 10. Everytime I switch my notebook on, I have to press F9, go to Boot manager, press Ubuntu and then GRUB menu is shown. I want GRUB to show when I start my notebook. Is there a way to do so ? If I don't press F9,Windows 10 is booted. I have disabled Fast Startup of Windows 10.

  • Are both Windows & Ubuntu in same boot mode, or both BIOS or both UEFI? Grub can only boot another system installed in same boot mode? Post the link to the Create BootInfo summary report. Is part of Boot-Repair: help.ubuntu.com/community/Boot-Info – oldfred Sep 20 '15 at 21:10

I have once had a similar problem with dual-booting with Microsoft Windows.

I solved the issue by taking the following steps.

  1. Boot into Ubuntu.
  2. Hold CTRL-ALT-T to open a terminal
  3. Run:sudo update-grub2 and allow GRUB to update it's list of operating systems.
  4. Close Terminal.
  5. Restart Computer.

Alternatively one could install and use boot repair HERE

This should hopefully sort out the problem and show GRUB upon start up instead of Windows Boot Manager. Good luck.

  • It didn't work actually. Further more somehow ubuntu has lost its sound. During startup its does give the initial ubuntu sound, but after that nothing. I tried disabling Windows 10 Fast startup but it didn't work either. – Abhi80 Sep 25 '15 at 4:50
