Inaccessible Boot Device Error in Windows 10: How to Fix it

As surely we all know, Windows 10 is a system that is updated every so often, either with large-scale updates, or with minor patches. However, sometimes we can find that it is installed and the computer is restarted, with what appears a blue screen of death or BSOD . In this we can find the commented error message, that is, Inaccessible Boot Device, which means that the boot device is inaccessible.

This comes from the fact that Windows lost access to the system partition during the boot process. Well, to say that this has several possible causes. In principle some users suggest that the problem seems to be more frequent on computers with SSD drives . Therefore, to solve the error in Windows , the first thing we can try is to remove the recently installed updates. These may be the cause of the failure, so its elimination could solve it.

To do this we go to Settings / Update and security / Recovery / Advanced startup / Restart now. After a few seconds, a blue screen will appear where we are located in Troubleshooting / Advanced Options / Command Prompt.

Once the Command Prompt appears on the screen , we write the commands “dir c:” and “Dism / Image: c: / / Get-Packages” to see all installed updates. Checking the date field, we identify the most recent one, we take note of its full name and to delete it we write “dism.exe / image: c: / / remove-package / [NAME_DATE]. This should solve the problem discussed.

Other possible alternative solutions

On the other hand, if this does not work, we can try to remove the pending updates . And sometimes they get stuck, that is, pending, but not installed. Therefore these can cause the Inaccessible Boot Device error. To remove them again we open the Command Prompt as we have seen previously.

But in this case we will have to execute the following commands:

“Reg load HKLM / temp c: / windows / system32 / config / software”

“Reg delete” HKLM / temp / Microsoft / Windows / CurrentVersion / Component Based Servicing / SessionsPending “/ v Exclusive”

“Reg unload HKLM / temp”

These delete the registry key “SessionsPending” so that we can move any pending update to a temporary file. We achieve this with the “dism / image: C: / / get-packages” command so that we can then create a temporary file through “MKDIR C: / temp / packages” and finally type “dism / image: c: / / remove-package / packagename: [UPDATE_NAME] / scratchdir: c: / temp / packages ”.

Another step we can take is to activate the AHCI mode in the BIOS of the PC, which could solve the mentioned error of the boot drive. Therefore we will have to access the BIOS and look for this functionality, since each manufacturer uses a different menu system.

Failures related to disk drives in Windows

Another possible solution that we can try is to update the disk drivers, as these may be defective and be responsible for the failure . This is something that can happen when using old drivers, hence the error that is Inaccessible Boot Device . This is something we manage to do from Device Manager. In that window we look for the ATA / SATA IDE controller, where we right-click and select Update Driver.

And finally we can check if the hard drive is damaged. To do this we place ourselves in the command line through the cmd command and open as administrator . Here we have only to type chkdsk / f / r and press Enter.
