Windows 10: Understanding Secure Boot

I don't really understand what this is? I made sure that I had it set to disabled when I installed Windows 10 Pro Anniversary Edition yesterday because I read that I should do that on the forums here. It was disabled by default on my MSI M/Board anyway.

I did install Windows in UEFI mode. Should I now enable Secure Boot? What does it do and what are the pro's and con's of enabling it?

:)

Hi Sebastian,

The issue is you are getting an error “secure boot violation - invalid signature detected”. We need some more information to assist you in a better way.

• Do you get any error code along with the error message?
• How did you install Windows 10? Was it upgrade or clean install?
• When you get a lot of words, is it on a blue screen?
• Have you updated chipset and BIOS drivers?
• Are you able to boot to the desktop?
• Did you try to boot in safe mode? If yes, were you able to boot?

Here is something we may try and check if this helps in resolving the issue with the error secure boot violation - invalid signature detected.

Method 1: Disable security boot

I would also suggest you to disable the secure boot and check. When your computer starts, wait for the manufacturer logo to check the option for boot menu, it will usually be any of the function key (eg: F12). Restart the computer; keep pressing the
Boot menu option key to enter the boot menu. Disable the secure boot option and check.

Method 2: Disable driver signature enforcement.

You may contact the computer manufacturer for further assistance if this doesn’t resolve the issue for changes in BIOS (Basic Input/output system).

Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting
from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

Original Title: Boot error

hey!

i want to dual boot, but when i start from my usb stick an error comes "secure boot violation invalid signature detected check secure boot policy in setup ".

 

Secure boot makes it more difficult to install non standard OS's that do not meet the modern UEFI standards, to ensure good design, and a major side effect of that is that it makes it more difficult for malware to hijack your PC as part of the booting process. So yeah, enable it for added protection. It will not affect Windows 8 or 10.

You would have to turn it off for Widows 7 or some other 'mon secure boot friendly" OS's if you wanted to dual boot.

 

Great thanks. Does it slow down the boot process at all?

 

The main idea behind it is it won't boot unless the system is correct the idea is if you get infected boot files it shouldn't boot

 

That information is incorrect.

You do not need to disable Secure Boot if you install Windows 8/10 in UEFI mode.

No.
