Windows 10: Inaccessible_boot_device BSOD after disabling driver signatures

I've been attempting to diagnose a broken driver for my fingerprint scanner which was giving me the error code 52, and tried to restart windows and disabling driver signatures. Up until that point, the computer had been working fine.


Upon disabling the requirement for driver signatures, I've yet to successfully boot my computer as it keeps getting BSOD after the startup spinner saying it has an inaccessible boot device. I've so far tried to use the system repair tool and DISM, though the former leads right back to the same BSOD error and DISM can't find a restore point on my disk.


How do I recover this without reinstalling windows and posing all my data? I have single install software that won't be recoverable, as well as work environments I would rather not have to recreate.

Disabling driver signature enforcement

Hi Fabio,

Driver Signature Enforcement is one of the security features that we make to make sure that only signed drivers can load on your system. Note that disabling driver signature enforcement will install drivers that weren’t officially signed. Install only the
drivers you trust. Follow these steps:

• Go to Settings > Update & security >
  Recovery > Advanced startup > Restart now.
• Choose Troubleshoot > Advanced options >
  Startup Settings > Restart > F7 or 7.

Once it restarts, you may now install any third party drivers. Note that the next time you device restarts, driver signature enforcement will be enabled again.
