How to enable Secure Boot Asus Tuf Gaming.

Error “Secure Boot Violation”: How to fix it

The error “Secure Boot Violation. Invalid Signature Detected” appears when the computer is launched by Windows. You can press Enter when it appears to enter the system, but it will occur every time when loading PC.

As a rule, the reason for the appearance of this message is incredibly difficult to determine. Judge for yourself: a short message on a red background that provides a minimum amount of information, and incomprehensible to many users. However, the first part of the message nevertheless gives a hint of how to get rid of this problem.

Secure Boot (safe loading) is a special protocol for BIOS, which prohibits the launch of non.authorized operating systems on the device. Thanks to this protocol in the BIOS, the signatures of the boot code of the original system are “remembered” and if these signatures do not match, Secure Boot blocks the loading of another system.

Solution “Secure Boot Violation

The decision is turned off the protocol

It is true that to get rid of the “Secure Boot Violation” error, it is often enough just to turn off the corresponding protocol in the BIOS. Perhaps you tried to boot into some other, additional OS that Secure Boot did not like.

One way or another, enter the BIOS by pressing the button allocated for this (for each it is different. google) when downloading a computer. For example, often these buttons are DEL, F1, F2 and so on. As soon as you enter the BIOS, we begin to look for Secure Boot item. Again, in each BIOS it can be located in different tabs.

Having found the necessary parameter, set for it the value of “Disabled”. Save the changes to the BIOS and reboot the computer. The mistake “Secure Boot Violation” should disappear.

Solution Deleting update KB3084905

It turns out that update KB3084905 released for Windows Server 2012 and Windows 8.1, can cause some problems with Secure Boot on computers that are connected to the same domain controller. Solution. delete the above update from the system. To do this, you need to do the following:

  • Press Windowsr;
  • Write the value of “Control.exe “and click Enter;
  • select “Deleting Programs” in the categories;
  • Click on the line “View installed updates”;
  • Find the KB3084905 update in the list, click PKM on it and select “Delete”;
  • Follow the instructions on the screen to remove the update;
  • Reload the computer.

We check whether the “Secure Boot Violation” error will appear or not.

Solution Disabling Digital Signatures

Let’s try to disable the mandatory check of the digital signature of the drivers. Some users claim that they managed to get rid of the problem with Secure Boot after disconnecting this function. One way or another, it will not hurt to try. Do the following:

  • Open the parameters of the system;
  • Select the section “Update and safety”;
  • Go to the “Restoration” tab;
  • Click on the “Reloading now” button;
  • On the screen selection screen, select the “Diagnostics” item;
  • Open the “additional parameters”;
  • Select the “loading parameters” and click the “Reload” button;
  • Now click on the F7 button to disconnect the mandatory check of the signatures of the drivers.

If you enter the system normally, then the message “Secure Boot Violation” really appeared due to a check of digital signatures. We hope that this article was useful for you.

General rules for disabling UEFI function

To disconnect, you can use various methods.

The first of which is possible if there is a Windows 8 or higher operating system on your device.

In this case, you will need to open the right panel and select the “Parameters” item, and then go to the section Changes in the computer parameters.

Then you should select the “Restoration” item in the “Update and Restoration” section and click on the “Reloading now” button using special computer download options.

In additional parameters, select UEFI settings and restart the device.

Another way to enter the BIOS of your laptop is to use the FN F2 keyboard.

After that, you will also get access to all BIOS settings.

Some OS “hot keys” may differ.

So in stationary computers this is most often the Delete key. And most laptops have F2.

In order not to make a mistake with which keys allow you to enter the BIOS settings on your device. you can see them on the initial screen at the time of launch.

To begin with, it is worth considering the BIOS InsideH20 Setup Utility settings with the existing UEFI function, as this is a common set of microprocorters for most laptops.

This includes devices of such brands as Acer and Toshiba, the translation of Secure Boot into an inactive state of which is somewhat similar.

Disconnect on Acer devices

Using the F2 key at the very beginning of the operating system load, open the BIOS window.

Having thus entering the BIOS UEFI settings, it will be necessary to go to the “Main” section and select the “F12 Boot Menu” item from the list present.

By default, this function is active, however, it should be deactivated by installing a parameter in front of it [Disabled].

In this case, you can get into the loading menu of your laptop after pressing the F12 key.

After that, it is necessary to move the keys with the arrows to the section “Security” and select “Set Supervisor Password”.

By pressing the Enter key, a password setting field is caused, the entry of which is required (then it can simply be dropped).

After its input, press Enter again to confirm.

In addition, a repeated entry of the same password is required in the lower field of the Set Supervisor Password window.

The result of these actions will be the appearance of the message that the changes were stored, to which you will press the input button again.

Next, you will need to go to the Boot tab and select the Boot Mode item, which is default in the UEFI position.

Select it and activate the Legacy option, and to confirm the Enter button.

After that, you should save the changes made by pressing the F10 button.

It remains only at the very beginning of the reloading of the laptop to press the F12 key. to get into its boot menu in which indicate one of the options for loading the operating system.

  • Secure Boot Control. Option for Turning on Safe Loading. Allows only the operating system allowed by the manufacturer.
  • You need to turn off if necessary to install OS. Additionally, it may be necessary to disable Launch CSM.

In the case of problems with the bios settings, a good solution is to reset them to the factory state. To do this, open the Exit section, where there should be an option with the name Load Optimized Defaults or Load UEFI Defaults (the name depends on the motherboard).

Secure boot disconnects on motherboard

The market of motherboards for desktop computers is quite conservative and explicit leaders are 2 companies: ASUS and GIGABYTE. They supply more than half of all equipment, so considering the methods of deactivation of Secure Boot most rational in the context of these manufacturers. In any case, MSI and ASROCK have long been occupied the third and fourth place. the first four consisted of Taiwan’s companies. Bottom line: there will still be no fundamental differences in the instructions for disconnection and most of the users will find below exactly what is looking for.

Note that you can go immediately to UEFI in some cases directly with Windows (from 8 version and later). To do this, try the following:

  • On the desktop on the right, call the retractable panel.
  • After following the path: “parameters” = “change in parameters” = “update and” = “restoration”;
  • In the window that has arisen, find the system reloading option and set in this line the value of “UEFI settings” or “ UEFI” parameters;
  • After that, click on the “restart” and in the future it should automatically start UEFI.

How to disable Secure Boot on the Gigabyte motherboard?

After entering UEFI (by pressing F12 before launching the OS), act as follows:

  • Go to the Bios Features tab;
  • Set the “Windows 8 Features” option “Other OS” for the criterion;
  • for the criterion “Boot Mode Selection”. “Legacy only” or “UEFI and LeGacy” (there is no particular difference between them);
  • For the criterion “Other PCI Device Rom Priority”. “Legacy Oprom”.

After all, you need to record changes, that is, press F10 = “OK”.

Maternal boards and laptops asus

Immediately, we note that most often on the maternity workers this manufacturer appears an error when loading the OS: Invalid Signature Detected. Check Secure Boot Policy in Setup. In most cases, the Secure Boot should be turned off to eliminate the problem, and for this you need:

  • Go to UEFI. click before loading OS on F2, Delete or FNF2 key combination;
  • On the initial screen, click on the F7 (Advanced Mode), and then go to the “Boot” menu = “Secure Boot Menu”;
  • Indicate in the line “Secure Boot State” the value of “enabled”, and in the line “OS Type”. “OTER OS”;
  • Return to one level back to the “Boot” menu = “Compatible Support Module (CSM)”;
  • Install the “Launch CSM” in the line “Enabled”, and in the line “Boot Device Control”. “UEFI and LeGacy” or “Legacy Oprom”, and in the line “Boot From Storage Devices”. “Both Legacy Oprom FIRST” or “Legacy Oprom First”;
  • After that, press on F10 and save all the changes, and then check the correctness of the settings performed.

Specifically for ASUS laptops, the algorithm will be as follows:

  • Go to UEFI;
  • Go to the “Security” tab;
  • Find the line “Secure Boot Control”, indicate in it the value of “Disabled”;
  • Go to the “Boot” tab;
  • Find the line “FAST BOOT”, set in it the value of “Disabled”, and the “Launch CSM” line “Enabled” in the line.

BIOS text intenses

To activate UEFI in BIOS, just switch certain parameters. Depending on the model of the motherboard and the firmware version, they may vary. In some integrations, just turn on the UEFI loader, in others you will have to change the security option “Secure Boot”. We also note: sometimes setting “Secure Boot” is not active until the user sets the administrator password on the basic integration itself. In this case, you should find the item “Administrator Password” and set the password.

In addition, keep in mind that many old BIOS do not support this mode. However, most of them can be updated to the version in which the manufacturer has added this function. In this case, switching to the UEFI mode will be possible thanks to one of the subsections in which the corresponding parameter is located.

Advanced tab

You can sometimes switch loading in the expanded settings section. Going to the Advanced tab, you should choose the Boot Option Filter and install it in the UEFI Only position.

Boot tab

The vast majority of UEFI activation will need to change the safety function. Usually it is on the Security tab in the Boot Secure section. To turn it on:

It is worth noting that “Secure Boot” can be on the “Autentification” tab. it all depends on the year of release of BIOS. In some cases, the download list of the load can be changed immediately from the Boot subsection. You need to select “Boot List Option” and switch the BIOS to UEFI mode.

System Configuration tab

Sometimes in modifications for InsydeH20, UEFI inclusion parameters are found on the System Configuration tab. Go to this section and open the item “Boot Options”. Here we are interested in the parameters “Secure Boot” and “Legacy Support”. “Secure Boot” must be translated into the “Enabled” position. If you want to prohibit unregistered devices, the Legacy Support option must be changed to Disabled. However, the latter is not necessary at all: in many revision of UEFI, the load is compatible with the Legacy mode.

UEFI graphic integration

On the new generation motherboards, the UEFI mode is set by default. However, if when configuring this parameter accidentally lost, it can be restored similar to text options.

However, to do this is not always simple: different manufacturers of technology based intenses on the standard Phoenix-Award, hiding different variations of its menu in advanced settings-“Advanced Mode”. Having opened the screen of this mode, sometimes it is enough to go to the Boot tab and put a box next to UEFI, and in some situations you have to look for the “Secure Boot” parameter to activate or deactivation of this parameter.

MSI has a number of versions whose inteys is very different from the standard menu. Going into advanced settings, you will see six panels-covers, each of which opens certain computer parameters. For activation of UEFI, you are interested in a list of BIOS tools, therefore:


UEFI inclusion in GIGABYTE integers is made on the BIOS Features tab, and in some versions the tab is simply called “BIOS”. Here you should switch the security mode “Secure Boot Mode” to the “Standard” position. Then turn on the Secure Boot safety settings themselves, translating their value to Enabled.

Z590 Intel Raid M.2, Secure Boot und TPM Bios Settings

In modern ASUS, the procedure is carried out just as in the old versions of these motherboard. You should open an expanded security mode and find a switch for this:

Other graphic shells

Almost all other graphic integrates place the UEFI load on the Security subsection settings settings. On this tab, you should find the Secure Boot option and activate it with an appropriate switch. In addition, check the Boot tab for the available Legacy and UEFI modes. The first can be deactivated at will, the second is activated without fail.

How to disable Secure Boot and UEFI on Acer Aspire laptop

Click the F2 key when loading the laptop and log in to UEFI-BIOS. Here we go to the “Main” section and, finding the parameter “F12 Boot Menu”, switch it to the “Enabled” position. With this action, we allowed the appearance of the laptop loading menu when pressing the F12 key.

Next, go to the Security section and, finding the set Set Supervisor Password, click on the Enter key. In the upper field we set the password (in the future we will drop it) and click Enter. In the lower field we enter the same password and press Enter again.

Click the Enter key to the message “Changes have been saved” once again.

Next, go to the Boot section and, finding the Boot Mode parameter, switch it from the UEFI position to the Legacy position.

In order for the changes to enter into force, click the F10 key and confirm the preservation of the changes by selecting “Yes”. Reboot the laptop. Since it makes sense to remove the password previously set (the ability to turn off/turning on the “Secure Boot” will remain), again we enter the F2 in UEFI-BIOS, go to the Security section and, finding the set SEPERVISOR PASSWORD, click on the Enter key. In the upper field we enter the previously set password and press Enter. In the second and third field we do not introduce anything, just by pressing Enter.

Click Enter to the message “Changes have been saved” once again. That’s all! The password is dropped, and the possibility of turning off/turning on the “Secure Boot” was preserved. In order for the changes to enter into force, click the F10 key and confirm the preservation of the changes by selecting “Yes”. Reboot. Now we will be able to download any operating system to our laptop.

How to disable Secure Boot and UEFI on the ASUS motherboard

Click the Delete key (perhaps F2) when loading the laptop and enter UEFI-BIOS. Click F7 to go to “Advanced Mode”.

We go to the “Boot” section, find the Secure Boot subsection there and go into it.

Switch the “Secure Boot” parameter to the “OTER OS” position.

Next, return to the root of the Boot section and go to the CSM (Compatible Support Module) “subsection)”.

Switch the Launch CSM parameter to the Enabled position.

In the additional options opened, select “Boot Device Control” and switch to the “Legacy Oprom Only” or “UEFI and LeGacy OPROM” position.

We move on to the Boot From Storage Devices parameter and switch it to the Legacy Oprom First or Both, Legacy Oprom First position.

With these actions, we were able to disable Secure Boot and turned on the expanded load mode. In order for the changes to enter into force, click the F10 key and confirm the preservation of the changes by selecting “Yes”. Reboot. Now we can download any operating system to our computer.

I can’t enable the safe loading mode for installing Winows 11

Good afternoon. In connection with the release of Windows 11, I decided to personally look out of curiosity at the new version of OC from Microsoft. Unfortunately, I faced a very unpleasant problem during the implementation of the requirement to install a new version of OC, the essence of which was not included in the safety mode of safe loading on my computer. Initially, the Windows 11 installer informed me that my device is not supported due to the safe load turned off on my PC. With grief in half, I was able to include this function in UEFI of my mother:

After that, to my surprise, the following picture awaited me in the information about the system:

I have not yet found a solution to my problem on the Internet, so I want to contact here for help with its solution. Suddenly, here someone also came across a similar situation and knows how to solve it.

Change the marking of the system disc with MBR to GPT (YouTube and Google to help, I did through the Aomei utility), turn off CSM in the bios and turn on the safe loading. Everything is quite simple and quickly done.

Same. You need to turn the disk from MBR to GPT.

Will not help.He has a system installed in Legacy mode and turning off the compatibility mode will simply not allow the system to load.You need to demolish everything.The same problem, only I put on update.Data is more important.

There is a converter in GPT, no need to demolish everything

Tried to convert the system disk? I read about it, but they say that the system may not start after this.

I personally tried it. I turned on the old BIOS Legacy. First converted a disk from MBR to GPT from Windows via CMD for UEFI/Secure Boot for Windows 11. It seems to have converted, but I could not turn on UEFI instead of BIOS, since there was no stupid choice of UEFI. Then I rebooted the PC again, I go into information about the system and see that the BIOS mode has changed to UEFI. Looks like a disk conversion from MBR to GPT helped and he himself systematically switched.

What commands for conversion used? I know only the one that cleans the data on the disk.

Check that conversion is possible. We launch a command line with admin rights and write in it MBR2GPT /VALIDATE /AllowFullos

If everything is fine. MBR disk and can be solved. Overload the PC through the Advanced Startup option in the Windows settings section

PC will overload the expanded load mode (blue screen). there we choose Trubleshoot (elimination of problems), then. Advanced Options (additional options). and after. Command Prompt (command line).

In the launched command line, we launch the MBR2GPT /Convert command and wait for the end of the disk conversion.

After the conversion is completed, overload the computer, go to the BIOS and switch UEFI, Secure Boot options and the correct loading. It will change to Windows Boot Manager

The other day I literally found out what can be adjusted through the Aomei Partition Assistant Pro. There, in two buttons, you can convert, without unnecessary actions from under Windows with CMD. Friends through this disk attached to this without loss of data.

Information on UEFI Secure Boot

This function can be useful for a corporate segment, as it allows you to prevent unauthorized loading of a computer from unauthorized media, which may contain various malicious and spy.

For ordinary PC users, this opportunity is useless, on the contrary, in some cases it can even interfere, for example, if you want to install Linux together with Windows. Also, due to problems with UEFI settings, during operation in the operating system, an error message may get out.

To find out if you have this protection, it is not necessary to move to BIOS and look for information about this, just take a few simple steps without leaving Windows:

  • Open the “Perform” line using the Winr key combination, then enter the CMD command there.
  • After the input, the “command line” will open, where you need to prescribe the following:

Depending on the manufacturer of the motherboard, the process of turning off this function may look different. Consider options for the most popular manufacturers of motherboards and computers.

For asus

Here, after entering the BIOS, you need to choose the section “Security”. There should be the “Secure Boot” parameter, opposite which you need to set the “Disable” value.

How to enable safe loading

Secure Boot is included through the standard “Windows” functionality or through UEFI.

Standard OS capabilities

To use capabilities, you must first make sure that the PC supports safe loading. If so, then:

  • Click Wini and reboot the computer as indicated in the previous section. But this time in the additional parameters, we select not the command line, but the “parameters built by UEFI”.
  • Reload PC.
  • Click “Entering” by choosing Secure Boot Control.
  • Indicate Enable and confirm our choice.

Now we leave the settings and confirm the manipulations made so that the computer is rebooted.

Why and how to deactivate Secure Boot in UEFI

UEFI has replaced the usual BIOS not only for convenience. One of its main goals is to detect malicious software and minimizing the consequences of its influence. The technology prohibits load along with Windows, and, as we already said at the beginning, the role of the defender got Secure Boot. On the part of the developers, the idea is successfully implemented in the form of a cryptographic model using EDS, electron-digital signatures. The correct actions of users and manufacturers are practically necessary.

The key points of the protocol include:

  • the presence of EDS in software components (system loaders, motherboard, drivers);
  • presentation by these components of their EDS to the computer in order to prove that they are not viral;
  • the presence of each PC of the original closed key.

To date, the main difficulty in using Secure Boot is the use of unified closed keys for all their products or lines by manufacturers.

Usually users usually disable Secure Boot if it is impossible to install or run the OS (in T. h. with a loading carrier). Many users believe that deactivation of the protocol will increase the rate of response of the components and operation of the processor. But safe download does not take away the system resources, t. to. functions at a low software level.

  • We enter UEFI and press Advanced Mode in the lower right corner (or F7 on the keyboard).
  • We move to Boot and activate the safe loading menu here.
  • The “Safe Loading Status” paragraph will indicate the value of “inclusive”.
  • Choosing “Keys Management”.
  • Click “Peel the keys”.
  • We confirm the changes made, after which we open the Exit tab and remain clicking on Save Changes Reset.

Disabiling ASUS Bios Secure Boot

Reboot the computer and continue to work without a safe loading mode.

Turn on secure boot via UEFI

To enable the protocol through UEFI, we reach the point “Keys Management”, as indicated in the previous paragraph, and select “Installing the keys safe”. Confirm the action by click on Yes, then we will maintain in the same way. After rebooting, the Secure Boot protocol will be active again.

What will happen after disconnecting safe loading

When working at the computer, you will not understand whether Secure Boot is functioning on your PC. If the protocol is disconnected, then the machine will not check the digital signatures of the components, but this also has its advantages: you can download Windows from a removable carrier, install several operating systems, run the previous versions of the OS, etc. D.

Safe loading is not supported? Update the equipment by buying a more modern PC.
