Can't enable Secure Boot on my BIOS.

    I have cleared CMOS and reflashed BIOS.
    Still get "CSM is Loaded! Disable the CSM via Setup and repeat operation after Restart" when attempting to enable Secure Boot Control.
    Perhaps I need to secure erase the disk -can't imagine that would help though...

    Sorry, I'm just posting in case someone else answers. Not trying to pester you
    Cheers!

    No, you are not pestering me at all. At this point I'm just glad we're both on the same page and all other support is more than welcome at this point. So, you have done what I have asked and now, before I provide additional suggestions, might I ask "what is driving you to install that secure boot option? Are you under the impression that it will lessen the possibility that you will be infected once you are fully booted into Windows 8 and browsing the internet?"

    repeat operation after Restart
    Is the Win 8 installer giving you that message? If so, it is either getting a Legacy response from the BIOS (which seems doubtful) or you are trying to do an incorrect install which could be caused by one of two things IMHO:

    1. Many UEFI BIOS's have a dual CD/DVD selection available from their one-time boot menu. One is for Legacy and the other is for UEFI boot. Mine looks something like this:

    Boot from Optiarc CD/DVD
    UEFI: Boot from Optiarc CD/DVD

    In your case, you must select UEFI (if dual options are available).

    The other issue might be that, if your are attempting a UEFI install from a USB stick, it must be properly prepared:

    UEFI Bootable USB Flash Drive - Create in Windows

    Somehow, I'm guessing if Thoeg stepped in right now, he could fix you right up if none of my suggestions work.

    How have you cleaned the drive? If you tried to install Ubuntu in Legacy mode, it might have placed something on the drive that is causing problems. So, if you did not clean it with Diskpart, you might try that.

    The latest Ubuntu kernel is Secure Boot compatible, so you can install it in UEFI mode just like Windows 8.

    It is partially a security thing, but if I'm honest it's also the watermark that bugs me. Call it a little OCD but it's a new computer and I just find it pretty annoying to always have the watermark.

    No, it's not the BIOS that pops up the message as soon as I try to change it, and then it leaves it unchanged. Which leaves me stumped as there's not CSM option in the BIOS.

    Hmmm. Well for the USB installer I used Windows 7 USB DVD Download Tool - is this appropriate or shall I try again as done in the above link?

    Yeah, that's what I was hoping to do after re-enabling secure boot.

    No, I only used the Window installer to erase it (and Ubuntu disk-repair once another time).

    I will try using Diskpart now -thanks!

    Also in addition I sometime get a

    "System BIOS detected a non-Windows 8 Logo grpahic card.
    There is no GOP (Graphics Output Protocol) support detected in this card.
    'Windows 8 feature, settings in BIOS will be changed to 'Disabled'

    Press F1 to run setup.
    Press F2 to load default values and continue."

    Would have mentioned this sooner but it doesn't always pop up.
    Going to start using DiskPart now anyway.

    As Windows 7 USB DVD Download Tool formats the in NTFS, you have install in Legacy mode.

    Remake the USB drive using this tutorial:
    UEFI Bootable USB Flash Drive - Create in Windows
    which will format to FAT32 for UEFI mode boot.
