Secure Boot in BIOS with UEFI support
Secure Boot Protocol Secure Boot, based on special certified keys available only for Windows 8 and higher, will not allow you to install the operating system on your computer from any installation media other than media with "eight" or "ten". Therefore, to start installing another system on your desktop or laptop, you will need disable Secure Boot in UEFI-BIOS.
The "Secure Boot" parameter, which is responsible for disabling the Secure Boot Protocol, is in most cases found in the "Security", "System Configuration" or "Boot" sections. But I want to say that to install, for example, Windows 7 on a new laptop with UEFI-BIOS, it will not be enough to disable only "Secure Boot" in the UEFI-BIOS, you also need to enable the compatibility mode with other operating systems.
The parameter responsible for this is called differently for all manufacturers: "Launch CSM", "CMS Boot", "UEFI and Legacy OS", "CMS OS". And it is, in the overwhelming majority, in the "Advanced" section, and in it, in the subsections "Boot Mode" or "OS Mode Selection".
On a laptop:
How to disable Secure Boot and UEFI on a Toshiba laptop
When the laptop boots, press the F2 key and enter the UEFI-BIOS. Go to the "Security" section and find the "Secure Boot" parameter, switch it to the "Disabled" position.
In such a simple way, we were able to disable Secure Boot in the UEFI-BIOS. But that is not all. Now you need to enable compatibility mode with other operating systems. We go to the "Advanced" section, find the "System Configuration" subsection and go into it.
Here we select the "Boot Mode" or "OS Mode Selection" parameter, and switch it from the "UEFI OS" position (possibly "UEFI Boot") to the "CSM Boot" position (possibly "UEFI and Legacy OS" or "CMS OS") ...
For the changes to take effect, press F10 and confirm the saving of changes by selecting "Yes". Reboot. Now we can load any operating system on our laptop.
How to disable Secure Boot and UEFI on an HP laptop
Sometimes it’s not so obvious. For example, on some HP Pavillion notebook models, you need to perform a few additional steps to disable Secure Boot.
Press the F10 key when loading the laptop (possibly ESC, then F10) and enter the UEFI-BIOS. We go to the section "System Configuration", we find the subsection " Boot options"And go into it.
Find the "Secure Boot" parameter and switch it to the "Disabled" position. On the other hand, we switch the parameter of the compatibility mode with other operating systems "Legacy support" to the "Enabled" position.
We answer the warning with “Yes”.
In order for the changes to take effect, press F10 and confirm the saving of these changes by selecting "Yes". Restart your computer. After the reboot, a window appears with the warning "A change to the operating system secure boot mode is pending ...". In English, we are offered to enter the code 8721 on the laptop keyboard (in your case, the code, of course, will be different) and press Enter. After this, the changes in the UEFI-BIOS settings will be saved and the laptop will reboot again.
When you turn on your HP laptop, press the ESC key and you will be taken to the start menu. In it, select "F9 Boot Device Options" and, going to the boot menu, select the installation USB flash drive (already connected) or the installation DVD with the distribution kit operating system.

How to disable Secure Boot in the UEFI BIOS? Hi admin, could you please give a quick overview on this topic? Very often friends have to reinstall on Windows 7, and for this you yourself know, you need to disable the "Secure Boot" option in UEFI. Laptops and computers from all different manufacturers and the interface is also different, respectively, the options containing this setting are slightly different and sometimes it is difficult to understand all this.
How to disable Secure Boot
Hello friends! Secure Boot protocol based on special certified keys (available only in Windows 8) will not allow your laptop to boot from any boot disk except for the installation disk with the "eight" itself. Therefore, in order to boot your laptop or computer from an installation disc with a different operating system, you need disable Secure Boot in BIOS UEFI.
The Secure Boot protocol option is mainly found in the Security sections, less often System Configuration or Boot, but I want to say that for Windows installations 7 for a new laptop with UEFI BIOS, it is not enough to disable only one Secure Boot option in the interface in UEFI, you also need to enable the "compatibility mode with other operating systems" and it is also called differently by all manufacturers: "Launch CSM", or "CMS Boot" , "UEFI and Legacy OS", "CMS OS", and is located in the main section of the UEFI BIOS called Advanced, then see the subsection "BOOT MODE" or "OS Mode Selection".
Let's look at the settings of the InsydeH20 BIOS setup utility, typical for all laptops, with UEFI elements, for example, Acer laptops have this BIOS, and then we will also consider other similar utilities that may have latest laptops and stationary computers.

Have you ever tried to install another operating system in parallel with Windows? If so, depending on what you were trying to install, you might have come across the safe UEFI boot(UEFI Secure Boot). If Secure Boot does not recognize the program you are trying to install, it will not allow you to complete the installation. Secure Boot is really useful for protecting your computer from malware... However, it also prevents the loading of quite "respectable" operating systems such as Kali Linux, Android x86 and TAILS.
Fortunately, there is a way to resolve this situation. In this article, we will show you how to disable the UEFI Secure Boot feature so that you can install a second operating system.
First, let's take a look at exactly how Secure Boot protects your system.
Secure Boot is a feature of UEFI, that is, a single extensible firmware interface, and UEFI, in turn, is a more advanced alternative to the BIOS interface found on many devices.
Secure Boot can be compared to a checkpoint. Before admitting a program to the system, it checks it. If the program is properly digitally signed, it is passed through the gate. If the digital signature cannot be recognized, Secure Boot prevents the program from starting and requires a system reboot.
But it happens that, although the program is safe and has a reliable source, its digital signature is not present in the Secure Boot database.
So, even if you download Linux distributions directly from their developer's site and check checksums to make sure that the software hasn't been compromised, Secure Boot can still "block" them. Other operating systems, drivers, and hardware may suffer the same fate.
How to disable Secure Boot
First of all, you should remember that Secure Boot is not just some annoying "feature" that you need to get rid of as soon as possible. In the end, this function is on guard for the interests of your own computer.
Also, keep in mind that when you re-enable Secure Boot, you may need to reboot the BIOS. In this case, you will not lose your data, but personal BIOS settings will be reset. In addition, it may turn out that once you disable Secure Boot, you will not be able to return it.
So, to disable Secure Boot, do the following:
- Turn off your computer. Then power on and enter BIOS mode again. This mode is usually entered using the F1, F2, F12, Esc, or Del buttons (depending on the computer model). Windows users can enter the menu additional parameters boot (Advanced Boot) by pressing Shift and selecting Restart. Then you need to click on Troubleshoot> Advanced Options: UEFI Firmware Settings.
- Find the Secure Boot feature. If available, select Disabled. Usually the Secure Boot option is found in the Security, Boot, or Authentication menus.
- Click on Save and Exit. The system will reboot.
So, you have successfully disabled Secure Boot. Now feel free to take a flash drive with an operating system that you could not install before, and try again.
How to activate Secure Boot again
To re-enable Secure Boot, you will have to remove all traces of the unsigned operating system from your computer, otherwise nothing will work.
- Uninstall any unsigned software installed while Secure Boot was disabled.
- Turn off your computer. Then power on and enter BIOS mode again. This mode is usually entered using the F1, F2, F12, Esc, or Del buttons (depending on the computer model). Windows users can enter the Advanced Boot menu by pressing Shift and selecting Restart.
- Find the Secure Boot option and select Enabled. Usually the secure boot option is found in the Security, Boot, or Authentication menu.
- If you fail to enable Secure Boot, try resetting the BIOS to restore it to factory settings. After resetting to factory settings, try enabling Secure Boot again.
- Click Save and Exit. The system will reboot.
- If the system does not boot, disable Secure Boot again.
Diagnosing an error preventing Secure Boot from being enabled
To solve the problem of a system boot failure with Secure Boot enabled, try the following:
- Check that in BIOS menu the UEFI option was enabled. This will also ensure that legacy boot mode is disabled.
- Find out the type of section of your hard disk... To do this, enter in search bar starting windows menu Computer Management (Computer Management). Next, select Disk Management. Find your main drive, right-click and select Properties. Now find the type of disk partition. UEFI requires GPT, not MBR, which is more earlier versions BIOS.
- There is only one way to change the MBR type to GPT: create backup your data and erase all information from the disk.
- Some firmwares have an option to restore factory settings (Restore Factory Keys), which is usually found in the same menu as other Secure Boot options. If you have such an option, restore factory settings, save them, exit and reboot.
If you cannot activate Secure Boot, the Trusted Boot feature will come to the rescue. True, it can only recognize the digital signature of Windows 10. Trusted Boot checks drivers, startup files, and other aspects of Windows.
If Trusted Boot detects a corrupted or malicious program, then, as with Secure Boot, it will prevent it from booting. However, unlike Secure Boot, Trusted Boot is capable of automatically fixing some bugs.
Collaboration between Secure Boot and Trusted Boot
Do you need Secure Boot?
It is worth remembering that by disabling Secure Boot, you are exposing your computer to potential threats.
We can say that today, at a time of rampant rootkits and other malware, secure boot is more urgent than ever. So, provide your UEFI system additional level safety, and sleep well.
If you bought a PC or laptop with a preinstalled operating Windows system 8, and then want to remove it to change, for example, "seven" or any version of Linux OS, then you will have problems with this, because of the secure boot system "Secure Boot".
Microsoft developers in development latest version Windows 8 completely dropped support for sixteen bit BIOS versions... Instead, the system has become 100% compatible with the so-called UEFI BIOS, which has a secure boot system “Secure Boot”.
Secure Boot is designed to prevent malware from running until the operating system and antivirus software are loaded, respectively.
It would seem that it is a very wonderful system, but, because of Secure Boot, it is simply impossible to install another operating system on a PC or software not having digital signature... Let's take a simple example. You bought new computer with preinstalled Windows 8 and decided to install on it additionally or instead of the "eight" OS Windows 7 or some Unix-like system. You can forget about this, the Secure Boot feature will not allow you to do this. If you do not agree with this state of affairs, then you will need to disable Secure Boot in the UEFI BIOS, that is, go into the I / O system and disable this annoying system.
Most modern motherboard manufacturers deactivate this function even before they complete the devices or go on sale. If the Unix developers of similar systems have already decided this problem having added support for secure boot UEFI BIOS to their operating systems, their colleagues from Microsoft do not intend to make changes to Windows Vista and Windows 7. And given the fact that these systems are used by many millions of people, it is easy to know how to disable Secure Boot necessary to fully enjoy the PC.
Disabling Secure Boot is very simple, for this you need to restart the PC and at the very beginning of its boot press the “Del” key on the keyboard several times (other key options are possible, for example, F8 or F2) to start the BIOS (input-output system).
We will not describe the process of disabling Secure Boot for all BIOSes (meaning software developers). Since this is simply not realistic, and we do not yet have such an opportunity to have desktop and mobile PCs of all manufacturers at hand. Let's take the example of Pheonix SecureCore Tiano, this BIOS is used on almost all laptops manufactured by Samsung, as well as for the UEFI BIOS Utility Asus.
- Disable Secure Boot in Samsung laptops. Go to BIOS in the Boot section. Find the Secure Boot option and set it to “Disabled,” then set the OS Mode Selection to “UEFI and CSM OS”. Ready. You should now be able to uninstall Windows 8 with Samsung laptop and install another OS.
- Disable Secure Boot in Asus laptops... Open the UEFI “Boot” section, then “Secure Boot”, then go to the “Key Management” option and change its value to “Crear Secure Boot Keys”. Done, intrusive feature disabled.
CSM is a compatibility module for the operating system. If your motherboard is equipped with BIOS (UEFI) developers other than those described above, then in addition to the described actions, try to activate the Legacy BIOS function.
CSM stands for Compatibility Support Module for Operating System... In other BIOSes (UEFI), you may need to enable the compatibility option: Legacy BIOS. If you have problems with the installation, you can try switching the SATA controller to AHCI mode... How to do this is written in the article "Enabling ACHI support for SATA drives"
8 and 8.1, after installing the updates, we encountered system errors that are associated with the so-called "secure boot". What is it? This is a feature that prevents unauthorized OS and software from starting when the PC is turned on. It is needed for additional protection of your computer from viruses and rootkits that can harm the system at the moment it boots. But what if the specified function causes persistent errors? It's all about given parameters... This article will take a closer look at how to properly configure Secure Boot. Let's figure it out. Go!
If there is such a problem, this article is for you.
There are a number of issues with Secure Boot mode. The most common error message is “Secure Boot is not configured correctly” or “Secure Boot Violation Invalid signature detected”. What to do in this case? It is often sufficient to simply enable the specified function through the BIOS. But some users do not have such an item in the BIOS at all. Then you should try to disable it. How to do this, further in the article.
Now you will know exactly what to do if Secure Boot settings are incorrect on your computer. As you can see, this situation is not difficult to fix. In just a few minutes, your system is working properly again. Write in the comments if the article helped you to deal with the error, and share with other users your experience in solving this problem.
