Hey all,

 

since Windows 11 released this week, i decided to try out it on our Business Notebooks. The installation of Windows 11 went fine with TPM and Secure Boot being enabled already in the BIOS. The OS installed just fine, started without problems.

 

But after I used it for 1-2 hours, and then sent the device into a Reboot, it wasnt allowed anymore to boot into Windows 11!

 

Everytime when i boot up now the Notebook, i get the error:

 

Secure Boot Problem

"Selected boot image did not authenticate. Please press enter to attempt boot to next device".

 

How can this be possible? I was literally using WIndows 11, and randomly HPs Secure Boot decided that the OS is not bootable anymore because it didnt get authenticated?

 

I did the BIOS Update to 01.17.00 Rev.A, didnt help.

 

Yes i can workaround this by just disbaled Secure Boot, but thats not a fix. Why should I enable Secure Boot for Win11 and then im forced to disable it because HP cant authenticated it?

 

Thanks for helping.

After some more tests. The 4th or 5th Reboot after Windows 11 is installed, im getting stuck at this Secure Boot Problem.

 

This was tested on 3x fresh installations!
