hi im just wondering if there's
a possible way to flash bios using the method of
fn+esc + power button in this model
my laptop only hangs on the acer logo
i installed a windows 10 64bit on legacy mode
but i accidentally load the bios to default
when i turn on the laptop it said
no bootable devices
after that it only hangs on the logo whats so ever
it does not enter the bios anymore
i tried the memory card and hdd in other units and its working fine
can someone please help me
where can i download a .fdd file for this unit
also in the support download link... they only support windows base flashing bios
my unit is ES1-431-C5AF
SNID:63909951676
please email me @ cjalanobinary@gmail.com if you find any solution anybody 
thanks
