ifl dvd fails /vmlinuz has an invalid signature

Post by markv2017 »

My 3.18 ifl DVD (nonet, with BIBM 1.48) fails at the first step with the above error. Just a bad disc I thought, so downloaded ifl 3.20 and BIBM 1.50 and burnt a new one. Custom setup so I can get rid of basic operation and add BIBM. DVD creation and validation reports OK from Makedisk.

Exactly the same failure. Strangely, if I create a bootable USB stick using exactly the same steps, that boots up fine and works.

MoBo is Asus P8Z77-V PRO.

Thought this must be a FAQ but I couldn't find anything.

What am I missing?

TIA

Mark

Solution was to go into the BIOS and switch off UEFI Windows Secure boot.

As I keep doing, I'd set my security to a level that inconveniences only me.

Solved, case closed.
