How To Fix INACCESSIBLE_BOOT_DEVICE Windows 10 Error?
There are several methods that could solve the INACCESSIBLE_BOOT_DEVICE problem within minutes. But at times, when the reason is unknown, you might need to try several methods. I have prioritized the list according to the top solutions mentioned by users who faced this problem. Let us begin.
#1 – Remove Recently Installed and Pending Windows Packages
If you are getting the Windows 10 INACCESSIBLE_BOOT_DEVICE error, then probably you are not able to boot or start Windows 10 on your PC. What you need to do in this method is get into Windows RE (Recovery Environment) to access Command Prompt. From there, you will be deleting the lately installed Windows Packages. To boot into Windows RE and delete packages, follow the steps given below:
Step 1: Boot your PC in Windows RE mode. For this, turn on your computer, and as soon as you get this INACCESSIBLE_BOOT_DEVICE error, hold the Power button of your PC till it turns off. It will take around 5 seconds of holding the power button. Now repeat this process a couple more times till you get the Preparing Automatic Repair screen as shown here. Wait till the diagnosis is complete.
Note: The Auto Repair screen may appear in the very first attempt as well. If it does, do not restart again.
Step 2: You will get the following screen after the diagnosis is complete. Click on the Advanced Options button to enter Windows RE mode.
Step 3: From the three options you get on the next screen, click on the Troubleshoot option.
Step 4: In the next screen, select the Advanced Options.
Step 5: Here, from the options, click on the Command Prompt option.
Step 6: This will open the Command Prompt in Admin mode. Here, you can check in which drive Windows is installed. Usually, it’s installed in the C drive, but it’s never a bad idea to make sure.
For this, simply type dir in Command Prompt and press Enter button. It will show in which drive Windows is installed.
Step 7: Now that you know in which drive you have Windows installed, run the following command:
Dism /Image:C:\ /Get-Packages
In the above command, C stands for the drive in which Windows is installed. If Windows is installed in D drive, replace C with D.
This will pull up the installed as well as pending update packages of Windows.
Step 8: From the list, identify the pending as well as the latest installed packages. You can identify the pending packages by the status code: Install Pending. To identify the latest package that was installed, check the install date.
Now, delete the pending and latest installed package, one by one using the following command:
dism.exe /image:d:\ /remove-package /packagename:[name of package]
In the above command, replace [name of package] with the actual name of the package to be removed.
So, if the package name is Package_for_KB4014329~31bf3856ad364e35~amd64~~10.0.1.0, then use the following command:
dism.exe /image:d:\ /remove-package /packagename:Package_for_KB4014329~31bf3856ad364e35~amd64~~10.0.1.0
Uninstalling the pending and latest installed Windows package may take some time. Let the process complete. Once it is done, close the Command Prompt, then restart your PC in normal mode.
This will most likely resolve the INACCESSIBLE_BOOT_DEVICE BSOD error in Windows 10. If it doesn’t try the method #2.
