Some PCs can’t boot after latest Windows 11 security update, no fix in sight —mostly affects 24H2 and 25H2 versions

A segment of Windows 11 users has encountered an issue with the January 2026 security update, resulting in some devices displaying an “UNMOUNTABLEBOOTVOLUME” error and becoming unresponsive. Users see a black screen with a message prompting a restart. This follows previous complications from security updates, including problems with shutdowns, hibernation, and disruptions to cloud applications like Outlook, OneDrive, and Dropbox. Microsoft has released emergency updates, but the unbootable error persists. Affected users can only temporarily resolve the issue by accessing the Windows Recovery Environment to uninstall the problematic patch. Additionally, the August 2025 security update disrupted recovery tools, and an October update rendered USB keyboards and mice inoperable in the Recovery Environment, complicating troubleshooting efforts.
