How to disable Secure Boot and UEFI on an HP laptop
Sometimes things are not so obvious. For example, on some HP Pavillion laptop models, you need to perform several additional operations to disable Secure Boot.
When booting the laptop, press the F10 key (possibly ESC, then F10) and enter the UEFI-BIOS. We go to the “System Configuration” section, find the “Boot Options” subsection and go into it.
Find the “Secure Boot” option and switch it to the “Disabled” position. On the contrary, we switch the “Legacy support” compatibility mode parameter with other operating systems to the “Enabled” position.
We respond to the warning with “Yes”.
For the changes to take effect, press F10 and confirm saving these changes by selecting “Yes”. Reboot your computer. After the reboot, a warning window appears with the warning “A change to the operating system secure boot mode is pending...”. In English, we are asked to enter code 8721 on the laptop keyboard (in your case, the code will, of course, be different) and press Enter. After this, 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 flash drive (already connected) or the installation DVD with the operating system distribution.

To disable it, set the value opposite it to [Disabled].
After this, go to the item “Legacy support” , which is responsible for compatibility with other operating systems.
Set it to the [Enabled] state, since this function is disabled by default.
The system will issue a warning for your actions, which you must ignore and select “Yes” .
Next, press the Enter button, after which a standard reboot occurs.
During this process, a window will open warning you that the operating system's secure boot mode has been changed.
To complete the settings, you will be asked to enter a four-digit code and press the Enter key.
After this, the computer will continue to reboot, and all existing BIOS UEFI changes will take effect.
When you start it again, you need to hold down Esc on the keyboard, which will allow you to enter the boot menu.
Here you will need to select the option to launch the operating system - hard drive, CD-Rom or bootable flash drive.

Solution
Now you will learn how to resolve the “Secure boot violation invalid signature detected” error. This is done extremely simply. But I advise you to take special care when reading this instruction, since we will be working with BIOS.
- First you need to go to SETUP before downloading. Usually, to do this, it is enough to press one of the keys after turning on the laptop: Del or F. There may be another button (or a combination of them), which is indicated on the screen in the first seconds of startup.
- Now you need to find the “SecureBoot” item among the options and set it to “Disabled”.
- For UEFI, you must additionally specify a different OS Type. Windows users, select “Other...” from the list.
- Also, I recommend enabling CSM (Enable CSM), if there is a similar option in the list of parameters.
Here are a couple of screenshots that will help you navigate the situation:
Now we check whether the “Invalid signature detected” problem in Windows 10 has been resolved.

Press the F2 key when booting the laptop and enter the UEFI-BIOS. Here we go to the “Main” section and, having found the “F12 Boot Menu” parameter, switch it to the “Enabled” position. With this action, we allowed the laptop boot menu to appear when pressing the F12 key.
Next, go to the “Security” section and, having found the “Set Supervisor Password” parameter, press the Enter key. In the top field, set the password (we will reset it later) and press Enter. In the lower field, enter the same password and press Enter again.
At the “Changes have been saved” message, press the Enter key again.
Next, go to the “Boot” section and, having found the “Boot Mode” parameter, switch it from the “UEFI” position to the “Legacy” position.
For the changes to take effect, press the F10 key and confirm saving the changes by selecting “Yes”. Restarting the laptop. Since it makes sense to remove the password we previously set (the ability to disable/enable “Secure Boot” will remain), again using F2 we enter the UEFI-BIOS, go to the “Security” section and, having found the “Set Supervisor Password” parameter, press the Enter key . In the top field, enter the password we previously set and press Enter. In the second and third fields, do not enter anything, just press Enter.

- as a result of scanning disks using antiviruses after a serious virus attack;
- if in your Windows settings you have allowed the use of drivers from unverified sources (without a digital signature);
- when you connect an additional HDD drive;
- as a result of an unsuccessful BIOS update/reset.

Write in the comments if these instructions helped you solve the problem with installing the operating system on your personal computer or laptop.
What is UEFI?
UEFI (Unified Extensible Firmware Interface, a unified interface that supports firmware extensions) is a software and hardware solution that replaced the usual BIOS (basic input/output system).
Through the interface, distributed in the form of one or more files, the user can:
- Manage low-level functions of hardware components. Doing this in an already loaded operating system is either not possible, or is fundamentally more difficult, and in the BIOS, due to the confusion of the menu and the predominant absence of the Russian language in the firmware, it is also quite difficult.
- Enable or disable booting the OS from certain media.
- Get additional information about the software and hardware configuration of your device, including finding out the model of the laptop and its individual components.
UEFI
Thus, UEFI, like the BIOS it replaced, serves as an “intermediary” between low-level hardware firmware and the operating system; Without using one of these interfaces, the user will either not be able to launch the OS at all, or will end up with a non-configurable machine that works with much less efficiency.
The first modifications of UEFI, then simply EFI, appeared in the early 1990s. A truly "unified" version was released by Intel in late 2000 as version 1.02. The current version 2.6 was released sixteen years later; Despite the active development of the interface, it is not yet possible to enable UEFI on all computers - developers face many unsolved problems, primarily related to compatibility issues.
Important: despite the fact that each computer and laptop manufacturer develops and implements its own version of UEFI, the principles of operation of the software and hardware combination are the same - not only for different equipment, but also for different operating systems, including Windows, Linux and MacOS.
