I have installed Ubuntu 14.04 (Trusty Tahr) along with Windows 8.1. When I turn on the computer I don't get an option to boot into Ubuntu, and I go strait into Windows. How can I solve this?

I have tried using boot-repair, but I could not install it on live Ubuntu (as the Internet connection is not working), so it is working in my 'installed' version of Ubuntu. There I am not able to use the 'recommended repair' option.

  1. Disable hibernation and fast startup in Windows.

    • Open command prompt as administrator and execute:

      powercfg /h off

    • Open Windows Control Panel.

    • Go to Power Settings.

    • Uncheck Fast startup.

  2. Shutdown the machine completely - do NOT reboot.

  3. Reinstall GRUB boot loader for Ubuntu in EFI mode.

    • Boot from the Ubuntu installation medium.

    • Select Try Ubuntu without installing.

    • Open a terminal and execute:

      sudo mount /dev/sda7 /mnt
sudo mount /dev/sda2 /mnt/boot/efi
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt
grub-install /dev/sda
update-grub

    Note:

    sda = disk | sda2 = EFI partition | sda7 = system partition

  4. Boot into BIOS and select Ubuntu as default system.
