Why can’t I update BIOS because keyboard isn’t recognized in flash utility?

I want to update the BIOS of my Asus notebook F3JC from version 305 to 307 but when I try to update it using the AsusTek BIOS ROM Easy Flash Utility V1.10 it doesn’t recognize all of the keyboard keys.

I even tried using another keyboard but only enter and escape work in both so I can’t select the drive where the file is.

Asus flash utility v1.10

What can I do?
