Many users who are not particularly knowledgeable about the settings of primary input/output systems quite often come across the Legacy USB Support item among the huge number of various parameters. Nobody really understands what it is in the BIOS, why this option is needed, since its default value is usually set to Auto. However, sometimes you need to change this parameter. That is why it should be given special consideration.
Legacy USB Support - what is it?
If we talk about the function itself based on its name, it is not difficult to guess its purpose. It is enough to simply translate this term from English. The interpretation of this option assumes support for devices that connect to a computer or laptop through the appropriate interfaces and ports, just at the level of the primary system, as was originally provided for all other hardware connected to the motherboard.
But if we say that this is Legacy USB Support, in this particular case we are talking exclusively about peripheral devices (mice, keyboards, etc.). Sometimes this parameter may also apply to removable storage devices. And although this is not directly stated, quite often problems associated with the fact that some types of flash drives are not detected when installed as the first boot device are eliminated by activating this option. However, as practice shows, these are isolated cases, and they are mainly associated with devices from little-known manufacturers or specific equipment that is not initially supported in the BIOS.
How to enable Legacy USB Support?
Now a few words about what actions can be performed with such parameters. To get started, just look at its original default value. This is usually the automatic support selection option (Auto).
But what is it? In Legacy USB Support, if you expand the list of all possible options for setting values, you can see both activation (Enabled) and disablement (Disabled). What is it for? Only so that the user can choose whether he needs such support. Of course, in the case of flash drives, if they are not detected even if they are first inserted into the port, after which the computer is turned on and then entered into the BIOS settings, activating this parameter is mandatory. Roughly speaking, you need to first insert the flash drive into the USB port, and only then turn on the power for the download to begin.
Is it advisable to enable this option?
But, since enabling the option is mostly associated with peripherals (most often, as already mentioned, with mice and keyboards), many users have legitimate doubts about activating it. Is the system itself unable to identify such components? It goes without saying that if we are talking about an operating system in which installed drivers are responsible for the operation of such devices, there should be no questions. But few people pay attention to the fact that when support is disabled, such devices become inaccessible the moment they turn on the computer or laptop (even before the main operating system loads).
In other words, an external USB keyboard cannot be used even to enter the BIOS settings. That is why it is not recommended to completely disable this option under any pretext. By and large, it is better not to change the automatic value for selecting whether to enable or disable support at all! But if you are working with outdated modifications of Windows, such as the network version of NT, this option must be enabled.
When it is deactivated, quite often it will be possible to observe a loss of functionality of peripheral devices, which will be indicated in the equipment properties in the “Device Manager” (the device is disabled, it needs to be turned on, etc.). The saddest thing is that there is no way to activate disabled devices in the manager in such a situation.
Results
What is Legacy USB Support, apparently, many have already figured out. As for the main conclusion that can be drawn from all of the above, it should be noted that it is better not to change the default value of automatic activation or deactivation if the specified support is needed, otherwise you will not be able to enter the primary system later. You will have to additionally connect old PS/2 keyboards and mice. But what should you do if your laptop doesn’t have such sockets, the main keyboard is out of order, and the USB ports don’t work when support is disabled? Here's your answer!
The security mode in UEFI, or security boot, provides startup protection on a laptop or desktop computer: it blocks access to changing the boot priority from a CD/DVD, USB drive (including the ability to use the OS from a bootable USB flash drive), prevents attempts installation of an unlicensed, unauthorized OS, unauthorized intervention in the boot shell. In such situations, when loading, the message “secure boot violation” appears on the display, indicating that it is impossible to modify the boot in the BIOS (in BIOS), UEFI.
To remove this blocking, you need to disable the corresponding options in UEFI. After disabling protection, you can change the boot priority from disks and USB flash drives, as well as install any OS distributions.
This article will tell you how to disable secure boot in boot shell options. It describes in detail how to turn off the protection mode on devices of popular brands, and how to find out using the system settings whether Secure Boot is enabled.
Checking whether a function is active
You can find out the boot protection activation status in two ways:
Method number 1: in options
1. Press the “Win” + “R” keys together on the keyboard.
2. In the Run panel, type msinfo32, press Enter.
3. Find the “Loading Status” option. View its value: "Off." - protection mode is disabled, “On” - included.
Method number 2: in the Powershell console
1. Run the utility:
- open the Start menu;
- in the search bar, enter the name of the utility - powershell;
2. Click the utility line that appears in the Start panel list.
3. In the console, enter the command - Confirm-SecureBootUEFI.
4. Press "Enter".
5. The system will immediately display the protection status after entering the command: True - enabled, False - disabled.
How to open UEFI/BIOS settings
To deactivate Security Boot, you first need to open the UEFI or BIOS boot shell. This procedure can also be performed in different ways:
Method No. 1: using “hot keys”
Restart the OS. Press "Del". If logging into the shell failed, then another hotkey is used to enter boot settings mode. This could be “F2” or the combination “FN+F2” (on a laptop).
Note. The BIOS button may be indicated on the monitor during system startup.
Method No. 2: standard OS option
(option for 8/8.1)
1. Activate the slide-out panel (on the right side of the screen).
2. Go to: Settings → Change settings... → Update and... → Recovery.
3. In additional add-ons, set the restart mode to “Settings via UEFI”.
4. Activate the "Reboot" command.

Bottom line
As you can see, the principle of disabling Secure Boot protection on different models is almost the same, with the exception of only some nuances related to the location of the menu and additional add-ons. Even if this review does not include the model of your PC or laptop, use the basic algorithm to deactivate the protective boot option. Namely: entering the UEFI shell → disabling Secure Boot (+ on some computers, enabling compatibility with other OSes) → saving the created shell configuration → rebooting the system.
Successful and quick computer setup! Be extremely careful when changing the value of options in the UEFI console.
UEFI Secure Boot- This is a standard protection on the BIOS, which limits the ability to launch USB drives as a boot drive. This security protocol can be found on computers with Windows 8 and later. Its essence is to prevent the user from booting from the Windows 7 installer and below (or an operating system from another family).
This function can be useful for the corporate segment, as it allows you to prevent unauthorized booting of your computer from unauthorized media that may contain various malware and spyware.
Ordinary PC users do not need this feature; 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, an error message may appear while working in the operating system.
To find out whether you have this protection enabled, you don’t have to go to the BIOS and look for information about this, just take a few simple steps without leaving Windows:
Depending on your motherboard manufacturer, the process for disabling this feature may look different. Let's consider options for the most popular manufacturers of motherboards and computers.
Method 1: For ASUS
Method 2: For HP
Method 3: For Toshiba and Lenovo
Here, after entering the BIOS, you need to select the partition "Security". There should be a parameter "Secure Boot", opposite which you need to set the value "Disable".
Method 4: For Acer
If with previous manufacturers everything was relatively simple, then initially the required parameter will not be available for making changes. To unlock it, you will need to set a BIOS password. You can do this using the following instructions:
Computers are developing more and more every day and this allows them to work even better and more reliably. Many have probably already heard about BIOS, and if you have already installed Linux, then you probably know what it is and have already had configuration experience. You've probably noticed that the BIOS is difficult to configure and use. This is low level software and has remained unchanged for the past two decades. Because of this, BIOS technology can now be considered outdated and in need of replacement.
The new system - UEFI will eventually replace the BIOS, but, like most new technologies, its implementation is moving very slowly and for a long time. Users are missing out on the importance of a low-level operating system, which is exactly what UEFI is trying to address. In this article we will look at the difference between uefi and bios, try to find out which is better, bios or uefi, and also determine which is better to use.
BIOS stands for Basic Input / Output System or in Russian - basic input and output system. This is low-level software that provides a layer between the computer hardware and the operating system.
The BIOS starts as soon as you turn on the computer, checks and tests the hardware, and then loads the operating system boot loader.
The BIOS board is built into every motherboard and, in addition to preparing BIOS hardware, can be useful in a number of other cases. Since BIOS is independent of the operating system, you can access its settings without having the OS installed. In addition, you can configure various hardware parameters - processor and memory frequencies, operating voltage, latency, and so on. This allows you to fine-tune your computer and get maximum performance.
Generally speaking, this is all that the BIOS does, there is only a pseudo-graphical interface, key controls and only hardware settings. The BIOS bootloader takes from the master boot record - MBR, and there can only be one bootloader. Naturally, there can be no talk about choosing a bootloader.
What is UEFI?
UEFI, or Unified Extensible Firmware Interface, is based on EFI - a development by Intel, which is designed to replace BIOS. The EFI standard has been developed over the past few years and has already begun to gain more popularity as manufacturers begin to use it on their devices instead of outdated BIOS technology.
UEFI supports all the features that were implemented in the BIOS, as well as many new features, which makes it the best solution for use on modern computers.
Here, in addition to initializing the equipment, reading settings from non-volatile memory and launching the bootloader, a large number of functions are supported. We can say that this is a low-level operating system. This is the main difference between bios and uefi. There is support for hardware drivers, and hence support for a mouse and graphics card; there is also a full-fledged console with support for launching applications, networking, and working with equipment. To the point where you can not only copy and move files on supported file systems, but also play discs or music if supported by EFI programs.
Although it has a significant advantage over BIOS, UEFI has some limitations on 32-bit processors. 64-bit processors fully support UEFI, but 32-bit processors do not support some functions and the operating system must emulate the BIOS environment for them in order to work normally.
On many devices you can now use two legacy bios or UEFI modes. During this process, many useful functions are lost. CPU makers and operating system developers are working together to fix this problem, and they're doing a good job.
Determining the UEFI or BIOS used on your computer is very simple; you can simply look at the computer's setup interface before booting. I think you will already understand everything here.
Which technology is better?
The old BIOS technology has been the industry standard for the past twenty years and during this time it has not seen many changes due to limitations such as only one megabyte of memory, 16-bit instructions and an MBR disk partition table that supports maximum 2 TB hard drives. and no more than four sections. Twenty years ago this was quite enough, but by modern standards such restrictions are too strict.
In addition, the flexibility of UEFI is necessary for technologies available now or those that will become available in the future. The BIOS limit of one megabyte created a lot of problems for hardware developers, but now there is definitely enough space to load device drivers.
UEFI is modular and, thanks to the GPT partition table, can support 128 partitions up to 8 exabytes in size. It also provides tighter integration with the operating system. A very important component of UEFI is increased security. This is an important difference between bios and uefi. Users can only install registered operating systems. Each operating system is given a key built into its boot loader, and the UEFI system reads that key and compares it to its database. If this key is not in the database, the operating system will not be allowed to boot. This could cause many problems with Linux distributions, but the problem has been resolved. In addition, users can add keys to the database themselves.
Thanks to the modular structure of UEFI, new features can be added later and thereby expand the existing system. This makes such a system more promising and easier to use.
Newer UEFI systems are much easier to use and have a full graphical interface with a mouse pointer and intuitive menus. You get the opportunity to configure everything very simply. In addition, motherboard manufacturers can develop various UEFI software modules that will allow easy testing of various hardware.
Overall, when comparing UEFI and BIOS, the former wins due to its modularity, extensibility, as well as independent drivers and ease of use. It will be some time before users can choose BIOS or UEFI and the new technology will slowly replace the old one. More and more manufacturers are using UEFI on their boards and computers, and 32-bit processors are being used less and less. But as with all advancements in computing, the transition to UEFI will take a long time. You now know the difference between uefi and bios and can make the right choice when buying a new device.
Secure Boot in Bios with UEFI support
The Secure Boot secure boot protocol, based on special certified keys available only in 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 computer or laptop, you will need disable Secure Boot in UEFI-BIOS.
The “Secure Boot” parameter, responsible for disabling the secure boot protocol, is in most cases located 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 UEFI-BIOS; you also need to enable 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 located, overwhelmingly, in the “Advanced” section, and in it, in the “Boot Mode” or “OS Mode Selection” subsections.
On a laptop:
How to disable Secure Boot and UEFI on a Toshiba laptop
When booting the laptop, 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 this simple way we were able to disable Secure Boot in UEFI-BIOS. But that is not all. Now you need to enable compatibility mode for other operating systems. 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 saving the changes by selecting “Yes”. Reboot. Now we can load any operating system onto our laptop.
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.
