I have a dual boot hp desktop with win 8.1 and win 7. After upgrading the win 7 hard drive to win 10 the Nvidia Geforce 440 graphics card cant be found, If I run the pc on win 8.1 the Nvidia graphics card works fine. The device manager in win 10 shows the display adapter is Microsoft basic display adapter. I tried to update the NVidia driver to version 358.50 but it won't install, reporting no NVidia card installed. I'm assuming the card is good because it runs ok on win 8.1. The only difference is the operating system. Is there a reason win 10 won't recognize the graphics card?
