Laptop starts Windows 8.1 after instlling Ubuntu 14.04

  • 772

I have a new HP Pavilion 15 with windows 8.1, and want to have Ubuntu alongside it. I created an Ubuntu 14.04 liveDVD, disabled fast boot, and changed the boot order. Then I installed Ubuntu. After that the computer still went straight to Windows (when the DVD was not in), so I disabled secure boot (even though some web pages say it's not necessary - can I put it back?). After that I followed all the instructions in Ubuntu 14.04 LTS release doesn't boot after being installed .

After the last step I got this link with tons of info.

All steps here completed without any error message, but still I go straight to Windows.

  1. Okay so there are are two things that could be happening here.

    A) You mentioned secure boot, implying a UEFI system. You may have installed the BIOS boot version of GRUB.

    B) You need to use a program such as EasyBCD to add a Linux entry into the Windows boot loader menu and make it visible on boot. Just Google EasyBCD for more info.

    Hope this helps !!!

  2. I have had problems with 14.04 on a newer laptop, but from some reading I found that 15.04 has the capability to install with secure boot enabled. I tried it two days ago and it worked just fine. I only disabled fast boot, but left secure boot enabled in UFEI. I have had success installing 14.04 after I disabled secure boot and fast startup. You might want to leave the UFEI in insecure boot and try to reinstall Ubuntu 14.04.

  3. Perhaps your Master Boot Records is damaged.

    1. Burn Ubuntu Live USB / DVD (You can do it via Unetbootin).
    2. Boot the machine in Live Ubuntu environment.

    3. Open up terminal and type

      sudo add-apt-repository -y ppa:yannubuntu/boot-repair;

sudo apt-get update;

sudo apt-get install -y boot-repair && boot-repair

    4. Once the boot-repair window pops up , click on recommended repair.

    5. Reboot. This might do the trick

  4. according to your report there is No boot loader installed...

    you have to (re)install GRUB, the default boot loader of Ubuntu.

    please have a look at: https://help.ubuntu.com/community/Grub2/Installing
