    0xc000007b BSOD on boot after Windows 7 to 10 Upgrade


    I just finished the upgrade from Windows 7 SP1 Pro to Windows 10 Pro and immediately after the computer fires up, I receive the error code 0xc000007b and the blue screen.

    I was able to get the computer up and running again via the "remove last windows feature" in the startup/repair options.

    Now that I'm up and running, I couldn't find any minidumps on my C drive to further investigate what was going on.

    Any suggestions where to look next? I'm back down to Windows 7, but it looks like there's a C:\$WINDOWS.~BT folder as well as C:\Windows\Panther that from some googling shows may contain helpful information regarding the upgrade.

    I scanned all folders/logs for the error code 0xc000007b and nothing turned up.

    I would like to attempt the upgrade again, but if there's something I can uninstall or do ahead of time, I'd love to do that first.

    I'm running an ASUS P8Z77-I DELUXE motherboard, which isn't "officially" supported under Windows 10, but it sounds like folks have been able to get it working.

    I've gone through all the Windows 7 updates, as well as updated the BIOS for my motherboard.

    :)

    Windows 10 upgrade problem, no input accepted

    I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

    After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

    I will list some, or hopefully all, of the troubleshooting steps I have tried:
    • Move keyboard and mouse to different USB ports.
    • Try different keyboard or mouse.
    • Restart computer, repeatedly.
    • Google for related issues.
    • Update Bios, because why not.
    • Create boot media and revert to windows 7.
    The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

    Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

    BSOD and 0xc000007b boot error

    I'm having an almost identical problem, but I cannot even reach a command prompt. This has been a stable system until this morning, now the BSOD shows that \Windows\System32\Drivers\aswVmm.sys (part of Avast Internet Security) is causing the 0xc000007b boot error... Doesn't seem to be any way around it that I've been able to find. Any suggestions will be much appreciated!

    0xc000007b BSOD on boot after Windows 7 to 10 Upgrade

    Windows 10 upgrade problem, no input accepted

    i've seen this when the stock USB drivers went kaput. Only ever seen it once - i used a PCI USB 2.0 card and connected the mouse and keyboard to that, and manually updated the USB 2/USB 3 drivers.
