    black screen on win 7 - dual hard drives win 8.1 on other


    Hey; When I try to boot to Win 7, I get the logo and then a black screen. I have tried all the repairs and nothing works. Win 8.1 is fine. Help and thank you.

    Boot the Windows 8.1 DVD/USB disk or Repair USB disk.
    System Recovery Options - Boot to in Windows 8
    Open> command prompt.

    Use the Rebuild BCD in this tutorial:
    Use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows

    Black screen


    I did not make myself clear. When I use Windows 8.1 everything works perfectly on the first hard drive. However, when I try to go into my other hard drive, which has Windows Seven, I get the black screen . I get the windows logo to come up and then it goes black except for the curser arrow running around the screen.

    Was that Windows 7 originally installed on that PC? Did it ever work correctly?

    Yes, it worked properly. I had a new motherboard installed and everything checked out. When I got home, the Windows 7 hard drive was not working.

    If the new motherboard has a different chip-set than the old one its likely a driver issue. Have you tried F8 safe mode? A major hardware swap like that may require a reinstall.

    Can't even get safe mode as an option on Win 7

    Recheck all your Data/SATA and power cables to make sure they are connected firmly. So Windows 7 worked fine on the new motherboard before you took it home? Is the new motherboard different from the old one?

    Yes, a new motherboard. Just returned from repair shop. Both hard drives worked fine. Came home and 7 still black. Crazy.

    Unplug any external USB devices like printers and try again. It's either something you've added since getting home, or something got knocked around some how. That or Windows 8 did something to the Windows 7 drive file system.
