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:From Windows, create a new partition on my machine to install Mint ontoCreated a bootable USB driveRestarted my computer and pressed F2 to enter the bios settings:Bootmode: UEFISecure Boot: DisabledBoot Order: USB HDD FirstMint boots from the USB drive and I install:The installer didn't recognize that I had windows installed, so I selected the something else option (IE not the remove everything option).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: UEFISecure Boot: DisabledBoot order: (see image)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.  Full computer information:The things that I am suspicious of right now are:Bad bios settingsWrong boot loader locationEditReinstall with different boot loader locationI re-installed and set the Device for boot loader installation to sda2 but that didn't make any difference.  Same behavior.  EditSteps to Boot into Linux Mint (in a unacceptably poor way):In bios set the boot order to use the USB HDDGrub will be launched.  Press ESC: Now you should be in Grub command mode.  Exit it by typing exit:Now you should be on the Boot Manager page.  From here you can launch the right grub (IE the first option): 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?  
Why is windows launching instead of grub. Bad bios settings? Wrong boot loader location?
