Microsoft fixed a Windows 10 issue that could cause booting to fail on devices using the chkdsk tool to repair logical file system errors.
chkdsk is a command line utility that can be used to check volumes of a Windows device for file system and file system metadata for logical and physical errors. While Microsoft does not say which Windows 10 versions are affected by this new known issue, it did say it fixed the issue with the updates KB4592438 and KB4586853 released for Windows 10 versions 2004 and 20H2 in December and November, respectively.
This problem affecting Windows 10 users was first reported by Günter Born, which was detected by Planet3DNow users.
Update distribution started
“Few devices that installed this update reported that their file systems could be damaged when running chkdsk / f and the device might not boot,” Microsoft explains.
For all unmanaged devices, the issue has been resolved, according to Microsoft, but it may take up to 24 hours for the fix to propagate to all affected devices. To speed up the process and prioritize the distribution of the fix on your device, you can reboot potentially affected devices.
“For enterprise managed devices that install this update and encounter this issue, it can be resolved by installing and configuring a custom Group Policy,” Microsoft says. See “For more information about using Group Policies, see Group Policy Overview. ”
Repairing devices that cannot be booted after running Chkdsk
Microsoft has already provided mitigation measures for customers who have already tried to run chkdsk and inadvertently damaged their computer’s file system.
To repair the boot capacity of their device, users are suggested to perform the following procedure:
The device should automatically start the Recovery Console after it fails to start several times.
Choose Advanced Options
Select Command Prompt from the list of actions
Enter the following command here: chkdsk / f
Let chkdsk complete the scan, this may take some time.
When done, type: exit
The device should now start as expected.
If it restarts in Recovery Console, select Exit and say continue to Windows 10.
After going through all the steps above, your device can rerun chkdsk automatically when it restarts to correct any logical or physical errors. However, after completing the check, the computer should restart as expected.
