    "Secure Boot Violation" Invalid signature detected. Check Secure Boot


    Never seen this message before but I can't get around it. All I did was reboot for a game and this popped up.

    I've gone into bios and secure boot is greyed out.

    How do I get around this?

    Running win 7 64 bit with an Asus x99-A motherboard. Specs updated below

    What is your BIOS version? Have you flashed it?

    Unfortunately as I have lack of experience with such an issue I can only refer you here:

    I am aware it says "Windows 8" but just have a read through it and get back to us.

    I haven't flashed it no. I tried the usb flashing but couldn't get it to work. Yeah I saw the same article dealing with win 8.

    My biggest problem is that in the bois that secure boot is grayed out so I'm stuck

    And I already have Launch CSM enabled

    It seems a recent "recommended" update could be the one causing the issue:

    Can you get into the Startup tools at all?
    If so you could run system restore to before the update was installed.
    I don't use secure boot on Windows 7 so I'm not sure.
    Do you have an earlier system image available?

    Hi,
    Yea although secure boot might be like that you should still be able to see and change OS type to Other OS without any problems.

    Hi,
    You might even go to the CSM section and make sure or switch between uefi only and or Legacy OPROM only and see if that makes a difference ?

    I can't get past the boot screens. Or should I say the on board RAID screen. Haven't tried booting directly off the CD though.

    I'm uploading some pics now and a short video of what I'm seeing if it helps.

    As you can see secure boot is grayed out.

    How was win-7 installed by the factory or by you ?

    Other os would work if not you'd have to try the CSM section of Boot and switch it to uefi only or Legacy only would apply to if you used Other OS.

    Switching to Other os would make the showing of PK State show Not loaded.
