    Had something like this happen to me, figured out that the link to the boot image from the BIOS got lost in the update.

    Fixed it by going into the BIOS and deleting the old link in the boot option to what was known on my computer as "Windows Boot Manager" and set up a new one to the physical location of the harddrive and the location of the boot image (/boot for Windows). No need to reinstall, this worked and my computer has been up and running since.

    Hi,

    Thanks for your reply. But im still not sure how to fix it.

    1. There's no error code. It just a red box pop up when i press the start button & it only got "ok" this option to choose. After i press ok the "Setup page" is the next page instead of windows...
    2. Bought a new laptop come with the window......not even 3 days i use it become like that after the update...regret to update it. Dont know this kind of things will happen.
    3. Not on blue screen....kind of MS-Dos?...black screen
    4. Not sure about it. No idea the upgrade got include updating of this chipset or BIOS or not...
    5. Nope....no logo or else...
    6. It dont give me boot to windows, safe mode ....

    But i'll bring it to the repair shop ask for assistance. Hope it can fix....Just want to know, will it happen again everytime if the windows get update? what if after i format the laptop or get it fix, it appear again each time the window update...

    Actually what is this error & how i get it? What the use of this secure boot?...if i off it forever, what the effect? Will the virus or scammer/hacker can get my information?

    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?
