Windows Won’t Boot After July 2025 Update? Fix Black Screen & Startup Loops (KB5060829/KB50602554)

Windows Won’t Boot After July 2025 Update? Fix Black Screen & Startup Loop (KB5060829/KB50602554)

Have you updated Windows in July 2025 and suddenly found your PC stuck on a black screen or trapped in a “Preparing Automatic Repair” loop? You’re not alone. Users worldwide—including business and home environments—are reporting boot failures after the latest Windows update. This guide explains what’s happening, why it matters, and exactly how to fix it (step by step).

Reported Symptoms You May Be Seeing

• Black screen with only the mouse cursor visible.
• Freezing on the Windows logo during startup.
• Automatic repair screen loading repeatedly (“Preparing Automatic Repair”).
• Blue Screen of Death (BSoD) after a few minutes, followed by automatic reboot.

In most cases, these issues start happening **immediately after restarting post-update**, making the PC unusable until addressed.

Affected Updates

Why It’s Happening (Possible Causes)

• Driver conflicts—especially graphics or security-related.
• Storage issues or BitLocker triggering during restart.
• Changes in Secure Boot or TPM configuration.
• Corruption in system files or failed updates during install.
• Potential overloading of system resources when Copilot launches early during boot.

Is Microsoft Copilot Involved?

For Windows 11, the July updates (KB5060829 and KB5060842) introduced changes to how Copilot loads immediately after startup. On systems with ≤8 GB RAM or under 10 GB free space on C:, this extra background load could delay system processes, resulting in black screens or freezes—even if Copilot is disabled manually.

How to Fix It (Step-by-Step)

Step 1: Boot into Safe Mode

1. Force shutdown 3 times to trigger Automatic Repair.
2. Go to Troubleshoot → Advanced Options → Startup Settings.
3. Restart and select Safe Mode (option 4 or 5).

If Safe Mode boots, you can uninstall updates or drivers from there.

Step 2: Uninstall the Problematic Update

Access Command Prompt from recovery or Safe Mode and run:

wusa /uninstall /kb:5060829

Replace with /kb:50602554 or /kb:5060842 depending on your system. Your PC may reboot automatically.

Step 3: Repair System Files

Still in Safe Mode or recovery, run:

sfc /scannowDISM /Online /Cleanup-Image /RestoreHealth

Step 4: Run Startup Repair

From the recovery environment, select Startup Repair. This will diagnose and repair common boot issues automatically.

Step 5: Use a System Restore Point (If Available)

If you had system restore enabled, restoring to a point before the July update can return your PC to a working state.

Step 6: In-Place Upgrade or Clean Install (Last Resort)

• In-place upgrade: Reinstall Windows while keeping your files.
• Clean install: Reinstall from scratch for a fresh system. USB media is required.

Real User Reports

Here’s what users around the world have been saying:

• “After the update, I got a black screen with just the cursor… it never progressed.”
• “Freeze on the Windows logo—nothing works, no matter how many restarts.”
• “Stuck in repair loop so many times, I had to reset completely.”
• “It boots, but then crashes with BSoD after a few minutes.”

These reports confirm the issue spans both home and office PCs, affecting a wide user base.

How to Prevent It From Happening Again

• Create a system restore point before installing updates.
• Temporarily hide the problematic KB using Microsoft’s “Show or hide updates” tool.
• Wait a few days after release before installing updates, especially on critical systems.
• Always keep backups of important files—either on external drives or in the cloud.

Sudden boot failures are alarming, but with a calm, prepared approach, you can handle them without panic.

Even if your PC isn’t booting now, the right tools and knowledge can help you restore it safely—without losing precious data. We hope this guide gives you the confidence to protect your system and stay secure.
