Product: Z440
I recently reflashed the z440 bios with the latest (2.57?) by moving the BBR jumper to the 2 pins closest to the back of the chassis. The bios on the usb downloaded and just as the computer was rebooting I unplugged it. Then I moved the BBR jumper to the two jumpers towards the front. Now, when the pc reboots. It says ‘secure boot’, ‘a request has been made to change this system’s secure boot configuration’, ‘please type in and enter the below number’. NO usb keyboards work: in any port, not the 2.0 ports or the 3.0 nor the 3.0 front ports.
is this now a brick?
