Inaccessible boot device

2018-01-21, 16:37 PM

My X1 carbon showed me error on booting after windows update (blue page). Before that , I found no USB device while I plug the USB Storage key to the USB port.

The message showed : inaccessible boot device

I tried all options in recovery but none of them solved my problem. Please tell me how to do now?

Hey there,

 

had the same problem with an windows 10 update. Solved it by using the RegBack Registry Backup that Windows automatically creates:

I got that after a failed Windows Update (in my case it was KB4054517), but I was able to recover to a previous System Restore Point and boot back up.    Once booted back up, I immediately disabled the Windows Update service, by running services.msc  to prevent Windows from trying to update again.     I then uninstalled the failed Windows Update (check update history) and then ran the stand alone installer for the failed update, found by searching for KB??????? on Microsoft's Update Catalog site, which resolved the problem in my case.

 

To run the System Restore, I booted to my Winodws 10 Windows Installation Media USB, selected "Repair your Computer" and then from Advanced Tools chose System Restore, but you should be able to do the same if you can boot to recovery mode.

 

If System Restore fails, you might try restoring the Registry Backups by following the steps in this link (in English)

Best of luck,
