Windows boots instead of asking which OS to boot

Question

I have successfully installed Ubuntu 14.04.2 LTS on my HP Compaq Laptop with UEFI, keeping my Windows installation.

I rebooted and was prompted if I wanted to boot Windows, Ubuntu or something like settings or more options.

I chose the last option and then chose to continue booting. The computer booted with Windows. I restarted the PC and it booted with Windows instead of prompting.

I'd really appreciate your help.

Answer 1

Disable secure boot. It worked in my Pavilion x360. I did it before installing Ubuntu. But because Grub and Windows Boot partition issues I installed the Grub in my Ubuntu root partition.
