Hi
Use the laptop serial number, find the original bios on the ACER website

I checked all the bios files, they don't have the .fd file.

Edit:
Did the, run exe file and get the folder in temp folder. It had isflash.bin no .fd file

Edit 2:

Followed this and found the .fd file name B5W1SX64.fd
Now how do I find that file

Edit 3:
Managed to flash bios. All I had to do was rename the isflash.bin to B5W1SX64.fd
