Question about Acer Aspire 5742Z-4200 Notebook
This is a pretty brave move if you haven't done this before and don't have access to detailed instructions as incorrectly flashing the bios can cause huge problems and make your laptop into a rather large and expensive paperweight so please be aware of the ramifications before you go any further.
I'm guessing that the updated bios files you've downloaded are in an ISO format in order for them to be "bootable" which would suggest that you need to change the boot sequence in the bios so that your thumb drive is the primary boot device and then reboot with the drive in place. Sorry I can't be of more help but Google is your friend. Good luck.
