Hi @mux121,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It seems like you're experiencing issues with Secure Boot and Platform Key management on an HP system after upgrading your SSD. I can offer some troubleshooting steps that might help resolve the issue.

Check Secure Boot Settings in BIOS: Ensure that Secure Boot is correctly set to "Enabled." You can do this by accessing the BIOS settings (usually by pressing F10 during startup) and navigating to the Secure Boot configuration. Confirm that the Secure Boot option is set to "Enabled."

Reset Secure Boot to Factory Defaults: In the BIOS, try resetting the Secure Boot configuration to factory defaults. This can sometimes resolve issues with key management.

Clear CMOS: Consider performing a CMOS reset, which can clear any residual settings that might be causing issues. The steps to do this vary between models, so it's best to refer to the specific user manual for your HP system.

Reinstall Windows: Ensure that your operating system is installed in UEFI mode, as some boot issues can arise from improper installation configurations.

Firmware Update: Check for any available updates for your system's BIOS firmware from the official HP website. Updating to the latest version can sometimes resolve compatibility and security settings issues.

Revert SSD Change: As a last resort, consider swapping back to your original SSD temporarily to verify if the issue is directly related to the new SSD.

For further information or technical documentation, consider referencing the UEFI pre-boot guidelines and Windows 8 UEFI Secure Boot for HP Business PCs.

I hope this helps.

Take care and have a good day.
