Symptom & Impact

Every reboot returns to Safe Mode, disabling normal services and reducing server capability.

Environment & Reproduction

Occurs after troubleshooting sessions where safeboot was left enabled in BCD.

bcdedit /enum {current}

Root Cause Analysis

The safeboot option remains set, forcing minimal startup profile at every boot.

Quick Triage

Check BCD for safeboot and alternate shell flags.

bcdedit /enum | findstr /i safeboot

Step-by-Step Diagnosis

Confirm startup mode and dependent service failures in current session.

systeminfo | findstr /i 'Safe Mode'
Get-Service | Where-Object Status -eq 'Stopped'

Solution — Primary Fix

Remove safeboot settings and reboot into normal mode.

bcdedit /deletevalue {current} safeboot
bcdedit /deletevalue {current} safebootalternateshell
shutdown /r /t 0

Solution — Alternative Approaches

Use msconfig Boot tab remotely if command-line access is limited.

msconfig

Verification & Acceptance Criteria

System boots in normal mode and disabled services return to expected state.

Get-CimInstance Win32_OperatingSystem | Select Caption,LastBootUpTime

Rollback Plan

Re-enable safeboot temporarily if a driver regression reappears after normal startup.

bcdedit /set {current} safeboot minimal

Prevention & Hardening

Document troubleshooting changes and enforce post-maintenance boot checks.

bcdedit /enum {current} > C:Tempbcd-current.txt

Related Errors & Cross-Refs

Can coincide with services marked as failed to start due to Safe Mode restrictions.
