Boot Configuration Data is a crucial database that contains boot parameters and settings required for Windows to start up properly.

For this purpose, EaseUS Partition Master offers a unique Rebuild MBR feature.

5. Boot in Safe Mode and Clear the Space

Safe Mode loads Windows with a minimal set of drivers and startup programs. It may work because:

  • It allows you to run anti-malware scans to detect and remove any malicious software causing the problem.
  • Performing a disk cleanup while in Safe Mode can free up space by removing temporary files, cached data, and other unnecessary items.

Check out these steps to boot your Windows in Safe Mode and fix the Diagnosing Your PC issue:

Step 1. Turn your device on and repeatedly press the "F8" key to access the "Choose an option" screen. Once accessed, choose the "Troubleshoot" option and go to "Advanced options."

Step 2. Afterward, select the "Startup Settings" options and enable Safe Mode by clicking the "Restart" button and then pressing "F4." After choosing this option, Windows will boot in Safe Mode.

Step 3. Now, open the Disk Cleanup and clear the space:

  • Hit "Win + R" to launch the "Run" window and enter the "cleanmgr" command.
  • Choose the Windows drive and hit "OK."
  • Finally, check the files you want to clean and click the "OK" button.

run disk cleanup

After this, you can restart your system in Normal Mode.

6. Run SFC and DISM

SFC and DISM are the command-line tools that can scan the system file errors and repair the Windows media. If the critical system files required for booting are corrupted, it can lead to startup issues.

Also, DISM focuses on repairing the Windows Component Store, which can cause boot problems if impaired. So, you can get out of the 'Diagnosing Your PC' screen by running the SFC and DISM using this method:

Step 1. After going to the "Advanced options" menu, as discussed above, head to "Command Prompt." Type the "sfc /scannow" command and press "Enter."

run sfc

Step 2. Now, run the "Dism /Online /Cleanup-Image /CheckHealth" command, press Enter, then "Dism /Online /Cleanup-Image /ScanHealth," again Enter, and finally the "Dism /Online /Cleanup-Image /RestoreHealth" command and hit "Enter."

run dism

You're good to go now after restarting.

7. Use System Restore Points

Windows has a feature allowing users to create Restore Points to get to a previous functional state if needed. So, using System Restore Points may help with this issue due to the following reasons:

  • You may install an impair software or make a significant change that causes this issue. So, restoring to the previous point can resolve it.
  • Even the corrupted Windows updates can contribute to this problem and can be fixed through Restore Points.

To use this fix for resolving the stuck on Diagnosing Your PC screen problem, follow this step-by-step guide:

Step 1. Once you reach the "Advanced options" menu, click the "System Restore" option. Then, hit "Next" and check the "Show more restore points" box.

Step 2. After choosing a desired restore point, click "Next" and "Finish."

click finish

Reboot your device to run it normally.

8. Uninstall Recent Updates

In this method, your Windows system removes the recently installed updates and gets to the previous stable update version. The reason for this action to work is:

  • Updates may occasionally introduce incompatibility issues with specific configurations, hindering Windows from booting properly.
  • In some cases, updates may not install properly and cause the system to become unstable. So, you can simply uninstall those updates.

These are the steps given below to uninstall recent updates.

Instructions. Head to the "Advanced options" screen and choose the "Uninstall Updates" option. Now, select the "Uninstall latest quality update/Uninstall latest feature update" option, and you can restart your PC to get it to the working state.

uninstall latest

9. Disable Auto Repair

Auto Repair is a Windows facility that diagnoses your PC and gets it to repair mode. This repairing mode is the one that lets your system go into diagnosing. So, if you disable it, you may bypass that stuck screen issue.

To disable the Auto Repair feature of your Windows, go through these steps:

Step 1. From the "Advanced options" screen, go to the "Startup Settings" option and hit the "Restart" button. After that, press the "F4" key to enable Safe Mode.

Step 2. After restarting, hit "Win + R" to reach the "Run" menu. Then, type "cmd" and hit "Enter" to access the command prompt. Input the "bcdedit /set recoveryenabled NO" command and press "Enter" to disable it successfully.

10. Recover Windows Registry

The Windows registry is a database that contains configuration settings and options for operating systems and installed apps. It can cause critical boot problems if it becomes corrupted due to software conflicts and malware.

Therefore, recovering the registry can restore it to a healthy state and resolve the Diagnosing Your PC screen scenario. 

Step 1. After getting to the "Advanced options" from the "Troubleshoot" menu, select "Command Prompt." Type the "copy c:\windows\system32\config\RegBack* c:\windows\system32\config" command and hit "Enter."

Step 2. A prompt will ask you about the type of data restore. Type "All" and press "Enter." After that process, restart your system and check if the issue is resolved.

11. Reinstall Windows

Now that you have tried all the above fixes and if the Diagnosing Your PC stuck screen issue persists, there's one last option left. You can reinstall the whole Windows to get rid of this situation. It creates an error-free fresh registry that won't need to be diagnosed.

Plus, it will install all the new system files and drivers without glitches and corruption. If you need to reinstall Windows, simply refer to this link and install it with the step-by-step guide.
