So, even though two mods said not to, even though you know you should only update the bios if its broken, even though it wasn't broken...
You did it anyway! Now it is broken!
All I can suggest is that you get the working version of a bios on a usb stick, nail alt+f4 until you get into the bios flash tool and flash it back.
If the flash went so wrong that you can't even do that - it's broken. See if you can get a new bios chip or its an RMA...
