Fixing the LOADER_ROLLBACK_DETECTED Blue Screen of Death (BSoD)

The LOADER_ROLLBACK_DETECTED error is a Blue Screen of Death (BSoD) characterized by the code 0x00000196. This error indicates that there is an incompatibility between the OS loader version and the operating system itself. Possible causes include hard drive issues, recent hardware modifications, corruption of system files, or problematic updates from Windows.

How can I resolve the LOADER_ROLLBACK_DETECTED BSoD?

1. Execute SFC and DISM Scans

1. Press the Windows key, input cmd in the search bar, and select Run as administrator to open the Command Prompt with elevated permissions.
2. Input the following command to scan and repair any corrupted system files, then press Enter: sfc /scannow
3. After the scan has completed, enter this command to fix the Windows OS files, and press Enter: DISM /Online /Cleanup-Image /RestoreHealth
4. Once all commands have executed successfully, restart your computer to apply the changes.

2. Check the Hard Drive for Errors

1. Press the Windows key, type cmd in the search box, and click on Run as administrator.
2. Next, input the command and hit Enter: chkdsk C: /f /r.
3. After the scanning process concludes, reboot your computer to see if the problem has been resolved.

3. Fix the Master Boot Record (MBR)

1. Power off your computer and power it back on three times until the automatic repair screen appears.
2. Select Troubleshoot > Advanced options > Command Prompt.
3. In the Command Prompt, enter the following commands, pressing Enter after each one:
   • bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd
4. After execution, verify if the error has been fixed.

The Master Boot Record (MBR) is crucial software that operates prior to loading the operating system, guiding the machine on how to boot from the hard disk. Damage or corruption to the MBR can lead to the occurrence of the LOADER_ROLLBACK_DETECTED BSoD.

4. Revert Your System to a Previous State

1. Press Win + R to bring up the Run dialog, type rstrui, and press Enter.
2. In the System Restore window that appears, click Next.
3. Select a restore point with a date prior to when the BSoD began to appear, and then click Next.
4. Follow the on-screen instructions to finish the restoration process.

This procedure should help revert your system to a functional state and eliminate the LOADER_ROLLBACK_DETECTED BSoD error.
