Updating bios error loading driver
Chances are you're doing something wrong, or have a bad usb thumb drive. Clear your bios, boot, then load defaults, and try to flash the latest bios.
If that fails, return it the motherboard to the place you purchased it and exchange it, or RMA the board through Gigabyte.
Don't try this unless you have a good reason to update your bios and can take the chance of killing your system (if necessary, wait until there is a better time to try this). Make sure your battery is charged and your AC adapter is plugged in before trying this. Don't try this in the middle of a lightning storm or when there are potential disruptions (wait for them to pass). If your system is having hardware problems like lock-ups, overheating, bluescreens, etc., it's more likely your bios flash will fail, so avoid flashing the bios if you see any of these problems and try to fix them first in other ways. Download the bios file for your notebook from the ASUS download site and unzip the bios file.
If you get cold feet and change your mind about flashing the bios, you can still choose 'No' at the prompt to abort the process. After the bios has hopefully flashed successfully, re-enter the bios to load the default settings under the bios 'exit' menu and save and exit.
Some people will copy the bios file to a USB drive for flashing, but I prefer to skip this step and just load the bios file straight from the hard drive. Enter the bios using the 'F2' key as soon as you power on the notebook.
Windows 8 users may have trouble getting into the bios with 'F2' (or through the 'ESC' key), so if necessary, boot to Win8 and select the 'settings' charm, Change PC Settings/General/Advanced Startup (restart now).
You should only update your BIOS if the new version contains an improvement you need. When you power your computer on, your BIOS takes control, starting the power-on self test (POST) and passing control over to the boot loader, which boots your computer’s operating system.
The BIOS is low-level system software that should “just work” without getting in your way.
BIOS updates aren’t big software upgrades that add new features, security patches, or performance improvements.
