boot phase

About this tag
The boot phase is a critical stage during Windows updates where the system restarts to apply changes. On WindowsForum.com, users report installation failures occurring specifically in the second boot phase, often accompanied by error codes like 0xc1900101-0x40000. These errors typically indicate problems during the migrate_data operation, where system settings and user data are transferred. Troubleshooting such failures may involve checking disk space, disabling third-party antivirus, or using the Windows Update Troubleshooter. The tag covers discussions about update-related boot phase errors, particularly with Windows 10 version upgrades like the Anniversary Update.
