I have a Medion Akoya E6412T MD99450 motherboard model D15D REV:2.0. The laptop didn't show a picture. I have now reprogrammed bios and the laptop now shows a picture but always comes bluescreen when i try to install windows. I suspect this is wrong Bios file, because at startup it shows no medion, but DEXP. I send the pictures and backup file. Can you look later, please. Thank you.
