@riccatizhg - I had to update the bios using a efi shell. I created a usb drive and booted to the usb drive. I was then able to successfully update the bios. There is more info on doing this here:

use method #3 to update the bios.
I had to reset the bios with the button on the back of the pc after I finished. But you might be able to get into the bios and do a reset there like the above instructions say. Good Luck!!
PS_ Be sure to use the bios in the post you mentioned above.
