Hi @Freya24,

Thank you for the details.

A "Secure Boot Violation" message typically indicates that the computer's BIOS is preventing the current operating system from booting due to a security measure intended to ensure the system boots. Here are the steps you can take to resolve this issue:

System Recovery: If resetting the BIOS to defaults did not resolve the issue, consider performing a system recovery using HP Recovery Manager. This process can restore the computer to a previous working state.
 

• Access the recovery environment by turning on your computer and pressing the F11 key repeatedly until the Choose an option screen is displayed.
   
• Select "Troubleshoot," then "Recovery Manager."
   
• Choose "System Recovery" or "Minimized Image Recovery" (if available) to restore the PC to factory settings or a previous state.

Disable Secure Boot Temporarily: This can sometimes help if a recent system update is causing the issues.
 

• Enter the BIOS setup by pressing the F10 key repeatedly immediately after turning on the computer.
   
• Navigate to the "Security" or "System Configuration" menu.
   
• Find the "Secure Boot" option and disable it, but be aware that this might reduce your system's security.

Check for Malicious Software: Once you can boot into Windows:
 

• Use Windows Security or a third-party antivirus tool to perform a full system scan to detect and remove any malware or viruses.

Please refer to one of our previous posts made by @Jerry_57 that has assisted other customers with the same issue.
