I am attempting to dual boot Linux Mint 17.2 (Cinnamon, 64 bit) and Windows 8.1 on my Acer E 15 (model # E5-573-55W1).

I have successfully installed Mint, but I can't get grub to start in a reasonable way. Here is what I have done:

  1. From Windows, create a new partition on my machine to install Mint onto
  2. Created a bootable USB drive
  3. Restarted my computer and pressed F2 to enter the bios settings:
    1. Bootmode: UEFI
    2. Secure Boot: Disabled
    3. Boot Order: USB HDD First
  4. Mint boots from the USB drive and I install:
    1. The installer didn't recognize that I had windows installed, so I selected the something else option (IE not the remove everything option).
    2. I created 3 new partition from the new partition that I made in windows, one for /, one for swap and one for /home.

Now I am confused, as to what my bios settings should be. I have the following set:

  • Bootmode: UEFI
  • Secure Boot: Disabled
  • Boot order: (see image)

enter image description here

When I boot, I don't get grub. I go directly to windows.

I know that my install worked because I was able to launch it through the grub on the USB. I can provide more detailed instructions on this if that would be helpful.

The things that I am suspicious of right now are:

  • Bad bios settings
  • Wrong boot loader location


Reinstall with different boot loader location

I re-installed and set the Device for boot loader installation to sda2 but that didn't make any difference. Same behavior.


Steps to Boot into Linux Mint (in a unacceptably poor way):

  • In bios set the boot order to use the USB HDD

  • Grub will be launched. Press ESC:

  • Now you should be in Grub command mode. Exit it by typing exit:

enter image description here

  • Now you should be on the Boot Manager page. From here you can launch the right grub (IE the first option):

enter image description here

  • This is what the right grub looks like. The first option will launch the installed version of linux mint (complete with the username I created during install). The third option will start windows.

The only question remaining, is why can't I open this grub on startup? What bios settings do I need?

The answer was posted over at askUbuntu and it worked for me. Thanks @gio900. I have copy & pasted the answer below (to avoid broken links):

So I resolved in the simplest way:

  • let boot mode UEFI enable, secure boot enable
  • in bios added the USB boot file of the distribution I want to install as trusted for executing:
    • My bios is: Phoenix SecureCore Tiano Setup
    • under Boot I flag Boot Mode UEFI
    • Secure Boot ENABLE
    • under SECURITY i select: "Select an UEFI file as trusted for executing"
    • in "Available File System" i select fs0:$nameofmyusbkey
    • select [EFI]
    • select [BOOT]
    • select BOOTx64.EFI
    • give it the name "whateveryouwant" then, using tab, select YES.
    • so I go to the Boot option, then put "whateveryouwant" as first in the Boot priority order
    • then I was able to start Ubuntu installation in UEFI mode! :)


before I did all them, I free the space for my partitions under win8, I read so many guide about UEFI and UEFI install (I give advice to do it!), and try in several way. That was the only way I was able to do what I want

Note: In order to add items to the boot priority order you must be have Secure Boot set to Enabled....

  • Your screen shots show you as having InsydeH20 firmware. It had exactly the same boot options?
