Microsoft rolling out a patch to fix chkdsk bugs causing boot failures

almost 2 years ago by IanDorfman

Microsoft has issued and begun rolling out fixes for errors identified in the chkdsk utility bundled with Windows 10.

As reported by German freelance writer Günter Born, Windows 10 versions 2004 and 20H2 suffer from a flaw related to the built-in chkdsk utility. In some cases, after either update is installed, if the user runs the "chkdsk /f" command in order to check for any and repair install corruption or damage, it can sometimes render the system incapable for booting.

Microsoft officially released fixes for these issues, one for each impacted Windows 10 build. It also released steps for how to recover from the bug if your system has already been impacted:

• The device should automatically start up into the Recovery Console after failing to start up a few times. • Select Advanced options. • Select Command Prompt from the list of actions. • Once Command Prompt opens, type: chkdsk /f • Allow chkdsk to complete the scan, this can take a little while. Once it has completed, type: exit • The device should now start up as expected. If it restarts into Recovery Console, select Exit and continue to Windows 10.

Microsoft also included a special Group Policy-based rollback for enterprise users that have encountered this issue when updating multiple systems at once. A link to it can be found on this official Microsoft Support article.

AlternativeTo recommends updating any systems that are currently running Windows 10 versions 2004 or 20H2 in order to avoid encountering this issue.
