I have two HHD drives, a Samsung SSD 850 and Seagate ST1000DX001. In BIOS setup > Main, Samsung is listed as Fixed HHD and Seagate as second HHD.

Press F12 UEFI BOOT list on line 1 Windows Boot Manager. Line two is Windows Boot Manger (Samsung SSD 850). The only way I can boot from my Samsung is by going to F12 and select line 2.

BIOS Boot sector only list Windows Boot Manager and no way to select which HHD to boot from.

How do I set which HHD drive to boot from at startup without going to F12.

Thanks
