Fix INACCESSIBLE_BOOT_DEVICE error in Windows 10

A new error showed up on my PC today. As soon as my PC showed the Desktop, Windows restarted itself automatically and showed the scary BSD (Blue Screen of Death). This was scary for me, as I have lazily not made a backup of my files for the last 3 months. Most of the stuff I read online about fixing this error suggested me to reinstall Windows 10. But that is quite annoying because, after the reinstallation, I’ll have to install tens of device drivers and adjust and customize hundreds of small settings which I am not willing to do.Windows 10

The INACCESSIBLE_BOOT_DEVICE shows up when Windows 10 can’t find the system partition during system startup. The only way to fix this is by fixing the boot partition using CMD from the advanced repair section. You will need to use the bootrec command to fix the boot partition.

  1. I can’t access the boot options screen on my windows 10. And the first picture in the instructions shows ‘continue to Windows 8. So that leads me to this only works on windows 8

    1. I believe you are having a problem in getting to the advanced boot menu. Right? Try Howtogeek’s guide to the advanced boot menu.

  2. Where’s the restart button on the pc?
