Windows 10 get INACCESSIBLE_BOOT_DEVICE after update - Microsoft Community

hi all

i'm experiencing problem happening on random pc in corporation (currently 6 pcs).

those pc have windows 10 (1607) , left powered on during night, started doing windows updates automatically.

the day after, pc show restore windows screen. rebooting show bsod inaccessible_boot_device

i've tried doing restore option recovery partition, none worked.

i've tried doing chkdsk /r, sfc /scannow, bootrec /rebuildbcd haven't changed nothing. disk/partition ok, , windows file accessible (from recovery partition).

i haven't changed bios configuration or hardware

there way debug happening? verbose mode show not accessible, or stop.

i've tried enabling boot log, not saved (i think cannot save file on disk, if cannot reach that)

how can understand why happened? i've checked eventlog files, stop @ moment pc rebooted, , haven't seen installation error of updates.

any way can refresh system files, without loosing software installed? i've done reinstall on of pcs, there wasn't software, there others have many professional software, take days reinstall.

thanks all

best regards

this should te solution. 

we test asap.

since delta update , cumulative update available @ same time, it’s important understand happens if deploy both updates in same month. 

if approve , deploy same version of delta , cumulative update, not generate additional network traffic since both downloaded pc, may not able reboot computer windows after restart. 

if both delta , cumulative updates inadvertently installed , computer no longer booting, can recover following steps: 
1.boot winre command prompt

2.list packages in pending state:

x:\windows\system32\dism.exe /image:<drive letter windows directory> /get-packages >> <path text file>


example: x:\windows\system32\dism.exe /image:c:\ /get-packages >> c:\temp\packages.txt


3.open text file piped get-packages. if see install pending patches, run remove-package each package name:

dism.exe /image:<drive letter windows directory> /remove-package /packagename:<package name>


example: x:\windows\system32\dism.exe /image:c:\ /remove-package /packagename:package_for_kb4014329~31bf3856ad364e35~amd64~~10.0.1.0
