Key 1: Remove your Recently Installed Packages

With my experience, I am sharing some solutions to troubleshoot the accessible boot device error in your Windows 10. So, let’s quickly explore the solutions that will fix that nasty blue screen on your Windows 10:

When you allow Windows to automatically install packages, it will always install the packages without any notification. So, you can always check if your Windows recently installed any packages and that might be the reason for the blue screen of death (BSOD) error.

Now, obviously, you need to uninstall recently installed packages one by one.

Save all your work and follow the steps below:

  1. Check properly if your machine is completely off. Now, press the power button to turn on your computer.
  2. Press the power button for 5 seconds and make sure this automatically shuts down. Now, you need to repeat this process more than two times and then, you will see ‘preparing automatic repair’ appear on your computer screen.

(Skip this step if preparing an automatic repair screen appears in the first attempt).

  1. After the windows diagnosis gets completed, click on the advanced options. This will open the windows recovery environment screen.
  2. Press the troubleshoot option and pick advanced options on the troubleshooting screen.
  3. Select the command prompt.

  2. Run DISM / Image: C:\/ Get-Packages
    With this step, a list of installed packages will appear on your screen.
  3. Uninstall the most recent package by entering dism.exe /image:c:\ /remove-package /[package name].
  4. Before this step, note down the package identity aka the package name that you jotted down in the preceding step.
  5. After uninstalling the packages, you are required to reboot the computer.
  6. Finally, you can check if the BSOD error has been successfully removed.

In case, the error is still there, try to uninstall the other recent packages with the same steps mentioned above.

Key 2: Update Your Drivers

You know that the drivers are the tools that enable Windows 10 to correctly use the hardware. But, do you know the fact that the drivers that are outdated are not consistent with an updated version of Windows 10. Therefore, these drivers may be responsible for causing all sorts of hitches, including that blue screen hitch. 

Simply, you are required to update the drivers in order to avoid these kinds of errors.

Update the outdated driver by:

  • Visiting hardware manufacturer’s official website > finding latest drivers > downloading them.
  • In most cases, controller drivers like IDE ATA/SATA are responsible to cause this boot device problem. Therefore, updating to the latest version will fix this error.
