Aspire ES1-523 exit from UEFI setup boots to UEFI setup

Hi guys,

Just got an Aspire ES1-523. Was setting up for dual boot of Win10 and Linux Mint 18. Shrunk Win 10 partition from within windows to make room for Linux partitions. Got system to boot from UEFI USB and used gparted from Linux Mint Live to make and format new partitions, then installed Mint using new partitions for"/" and "swap".

All seemed fine until reboot... Now boots to UEFI setup and exit from UEFI setup goes to boot and boots UEFI setup. I'm locked in a bit of a loop...

How can I get the boot loader to point to Win 10 boot manager or grub2 boot manager instead of UEFI (bios) setup???
