Secure Boot Violation

[Kaysho]

I cannot seem to get my PC to boot. My system was disconnected without proper shut down and have had the secure boot violation ever since. Watched a number of YouTube videos they all seem to be instruction install or reinstall my OS Win 1O. I don't know how to do that?

Hi:

Have you tried this option?

How to Fix the ‘Secure Boot Violation’ Problem on Windows 10/8/7 [Tutorial] - YouTube

If that didn't work...

What happens if you go into the BIOS and disable Secure Boot?

Perhaps the PC will boot up again.

To get into the BIOS turn on or restart the PC.

Immediately press/tap the ESC key to get the menu of options.

Select the F10 setup option and press the Enter key.

Within the BIOS there should be an option to disable secure boot.

This link may provide additional guidance to help you find the setting.

If it comes to the situation where you have to reinstall Windows, do you need to recover any important files, or can you afford to lose them?

I can give you a relatively easy way to factory reset your PC, but it will erase the contents currently installed on the hard drive.

If you need to try and recover files, I will give you a different option.

Yes I did watch the video was able to get into BIOS screen with F10 and disable secure boot. However, what I got when saved and exited is " BOOT DEVICE NOT FOUND. PLEASE INSTALL OPERATING SYSTEM  ON YOUR HARD DISK. HARD DISK - (3F0)" screen 

What's  my next option - a Legacy boot?

Were you able to disable secure boot, but to leave the legacy mode disabled?

If you enabled legacy mode, that may have caused the PC not to find the operating system because legacy mode uses a different boot structure (MBR) and secure boot uses the GPT boot structure.

Usually, you can do disable secure boot but not have to enable legacy mode on desktop PC's.
