My windows 10 pro pc stopped booting 2 days ago. I went thru all the advanced options to repair it and the screen to disable options and that stuff. I do ok with computers but this has me worried. In my PC I have 4 hard drives and I kept a working Win7 Pro on one hard drive, the others are dedicated to music production using Win10 Pro as my boot operating system for all my recording software.

It stopped working about 2 days ago after the computer froze forcing a reboot. May have been an update. Using the bios I can boot into win7 fine and I can see all the win10 files on the hard drive.

I had Microsoft support remote login today which was no help, they told me the only way to fix it is a custom win10 install and lose all my apps. I have an assure plan and sometimes they make nervous it just seems so scripted.

There must be a way to fix this without forcing me to lose my current win 10 setup. If you have any ideas please let me know and yes I have searched google and youtube for fixes. Hard drive checks out fine it is no doubt a win10 startup issue. The 0xCA error can occur if Winlogon. This happens if:. Unplug all external devices like flash drive, printer and scanner etc. Refer to the following link to download Windows 10 ISO file and create installation media.

Insert the Windows 10 DVD and restart your computer 2. Boot from the DVD. Choose your language and click next. Modifications of the settings are at your own risk. Was this reply helpful?

Only apps that came with your PC will be reinstalled. If you upgraded your PC from previous version of Windows, resetting your PC will restore earlier version.

But it also removes all the application programs I have installed…. On my digital work station I use well-known DAW software which requires an install and then I have to register it with the maker to work.

I had a working machine and after an update it now seems useless, Is windows 10 that picky that a corrupt file cannot be repaired or a new one copied over it? Please be informed that performing start-up repair and rebuild BCD, wont remove any third party applications installed.

Hey Bill, How about a courtesy flush? I was also able to at least login back into my system by disabling driver signature enforcement temporarily. But is there any permanent means through which this option can be disabled? It is really difficult to each time wait for the Automatic Repair Window to appear and then chosing this option. I have started facing this problem after I got my motherboard replaced in my Acer laptop. It was having original copy of Microsoft Windows 10 Pro installed in it.
