Hello,
I just bought a New ProDesk 400 G3 with freeDos and I would boot with a USB, but no reaction, I entered to the Bios Menu, I found that the secure boot was enabled, I tried to disable it then it gave me that was disabled but when I rebooted the PC, I found the same problem that the secure Boot was not disabled.
Please advice.
Best regards,
Nour-Eddine KEHY.
