Hello everyone,

 

I confirm that I searched the forum for an answer before posting here!

 

I want to disable Secure Boot in the BIOS of an HP Zbook Fury G9. I think I need to do this so I can install a new OS (Linux) from a bootable USB. With my current BIOS setup (secure boot enabled by default), I got a message that the image is not authenticated.....

 

I saw in this forum a previous post with the same title and I tried to follow the instructions described in the URL but it's not the same version/reference and the BIOS menu is different and I can't find no "legacy" choice in my BIOS.

 

I tried unchecking the "Secure Box Enabled" box and after confirming it asks to enter a 4 digit PIN. I do that (or I think I do that). On the next reboot I go back to the BIOS menu for Secure Boot and the box is checked again. I don't understand... so I need your help.

 

I tried several times.

 

Regards
