Hello,

system: Latitude E6530

I want to disable all UEFI boot options when system ist booting.

In BIOS setup under Settings --> General --> Boot Sequence, I can configure the boot list options for UEFI. But when I disable all options (NIC, USB, DVD, ...) and apply, they appear anyway at booting system pressing F12. The same, when I delete all boot options. When I go back after booting to BIOS, the options are there again.

With legacy options it's fine, all changings appear at booting.

What I have to do? Is there a additional box which I have to check?

 

Best Regards

Thomas
