Hello :)

I had a similar problem, what I did to fix it was:

After pressing "ok to enter setup" go to Boot tab and where it says "Launch CSM" press enter and enable it.

On the Security tab, select "Secure Boot Control" (it appears on the buttom) and disable it.

Hope it helps
I found this helpeful as well while converting a Windows 8 machine into an ESXi server for training; thanks.

It sure helped me, thanks. I have the ASUS N56DP NoteBook & was running into same problem because I was going from Win8 back to Win7. Your suggestion of 'Disabling' my "Secure Boot Control" which is located in my BIOS under 'Security' Tab. Again, thanks for your input.

Thanks, this also solved my problem. Now is this a temporary thing that I can re-enable later or am I forever stuck leaving off secure boot now? I take my PC security seriously and would like to be as secure as possible.

Thanks,

Same thing just happened to me. I have a Dell Venue 8.1 Pro - windows updates complete, but did a Chipset update and now I'm getting the Secure Booth Violation. I managed to turn it off and reboot the tablet and had to use the BitLocker recovery key.

I got the tablet restarted after that and re-did the Chipset install to make sure it was successful then went back into the BIOS and enabled the Secure Boot option only to be faced with the same Secure Boot Violation message. Back into the BIOS turned off Secure boot and then was faced with the BitLocker key setup again.

I tried uninstalling the updates, but that action failed. Machine said it encountered an error and was unable to restore. That's the second machine I've seen the restore point error in this month.

Sooo, is it a windows update that caused it, or is there something else going on?
