If you can't follow the maker's directions then you should not update the BIOS.
Imagine the poor soul that made up another method and bricked their laptop. Now imagine if their were your friend and you bricked their laptop.
This can't end well and why I suggest you always use the supported, documented methods or don't do it.
Can you help with a Boot On Flashdrive Or CD?
What are any methods to boot to update the BIOS? Sometimes the Laptop or Desktop will not update the BIOS with the standard methods.
Can you boot with Linux or UbunTu on a Flashdrive or a CD? Then flash / update / the BIOS? But after creating a bootable CD how you can copy the BIOS file over to it?
Thank you for all of your time and new and creative ideas.
