How to disable Secure Boot protection in BIOS with UEFI support. How to boot from a flash drive or disk into Asus uefi bios utility ez mode? Old bootable flash drives

Hello, dear readers! Today we will talk about one seemingly complex topic, which will sound like this: UEFI Boot - what is it? and how to disable UEFI in BIOS.

Of course, for the average user, all these names and abbreviations mean nothing, but nevertheless, when buying modern desktop computers and laptops, you will still come face to face with these concepts.

Yes, friends, this is the same settings section on a blue background, which you can enter at the very beginning when you turn on the computer. Here's a picture to refresh your memory:

Many more enthusiasts here have tried to play with the voltage and frequency of the main processor in order to increase the power of their machine. So, the BIOS microprogram was replaced by another, more modern one.

And as you already understood, it is called UEFI. Among the new innovations in it are support for high screen resolutions, very large disks and work with a mouse.

If you read all the lines above and did not understand anything at all, then watch a short video to reinforce the topic:

So, it should definitely be said that a full-fledged UEFI system is not yet implemented in all modern computers. But some of its new functions, hitherto unseen, have been successfully implemented into the old BIOS shell.

And one of them is the so-called UEFI Boot (full name Secure Boot). The point of its work is to prevent substitution of the system boot source, thereby reducing the use of unlicensed software.

That is, the picture turns out to be such that now we will not be able to boot, for example, from a flash drive or a third-party drive. Indeed, in this situation, they simply will not be in the list of available devices:

But in fact, this problem can be solved and very easily. To do this you need to make a couple of settings and that’s it. So let's get to work. So to speak, enough theory.

And in order to disable UEFI functions in the BIOS, you must immediately enter it. As mentioned above, to do this you need to press a certain key combination immediately after turning on the computer.

Thus, we have disabled the main UEFI protection function from third-party bootloaders. Then you should go to the “Boot” section and set the parameters as in the screenshot below:

After this, we should have a list of available devices. Now, by changing their position in the list, you can manipulate download sources. Again, using the author’s example, this can be done with a keyboard shortcut Fn+F5/F6:

Well, after all the parameters have been entered, all that remains is to save the changes. This is done in the "Exit" menu by selecting "Exit Saving Changes":

That's all, my friends, now you know exactly the answer to the question: UEFI Boot - what is it and how to disable UEFI in the BIOS. If you have any questions, feel free to ask them in the comments.

Well, if you suddenly want to learn more about UEFI BIOS, then watch a short video where this topic is covered more widely.

They brought me a laptop the other day ASUS X541N. They asked me to install Windows 10 or Windows 7 on it. I have a multiboot flash drive with different versions of operating systems, which I made a couple of years ago. I stuck this flash drive into the laptop, turned it on and began to press a key on the keyboard Esc. I thought I could quickly get through the Windows installation, but that was not the case.
After pressing the key Esc A window appeared asking you to select a boot device. But on the list my flash drive was missing– only the laptop hard drive was present. In this window I went to the “Enter Setup” item. A modern UEFI BIOS of an ASUS laptop appeared on the screen in front of me -:

Moreover, in UEFI Bios my flash drive was displayed in the “ USB Port”, but in the section “ Boot Priority“she wasn’t there. This meant that I would not be able to select it as a boot device and install Windows from it.

Then I decided to try change bios settings– I’ve already done this before (it also had a UEFI Bios). I’ll say right away: if this helped in the situation with Lenovo, then it was with this On an ASUS laptop, changing the settings did not do anything:

I switched to “Advance Mode” - in the section Security disabled the secure boot protocol (set the parameter Secure Boot Control to Disabled):
Further in the section Boot disabled the option Fast Boot(fast loading):
Then I saved the changes and rebooted. After the reboot, I again entered the BIOS section Boot.

But in this section there was no option and did not appear “Launch CSM” (and no other similar ones, for example: “CSM”, “CSM Boot”, “CSM OS”, “Legacy BIOS”). In other ASUS laptop models, after activating this option in the Boot section, it became possible to boot from a flash drive.

_______________________________________________________________________________

And now I’ll tell you how I solved this problem and still installed Windows on ASUS laptop:

Modern laptops have UEFI Bios. In order to boot from a flash drive in UEFI mode without any problems and install Windows on a GPT disk, this flash drive must be formatted in the FAT32 file system.

Therefore, if your computer’s BIOS does not recognize your flash drive as bootable, then first check what file system does it have?.

I inserted my flash drive into another computer - I went to its “Properties” and saw that it was formatted in the file system NTFS:

Then I just cleared it and re-entered the file system FAT32.

After that, I inserted it into the ASUS laptop again - turned it on - pressed the key several times Esc on keyboard. A window appeared asking you to select a boot device - and this time in it, in addition to the laptop’s hard drive, there was also my flash drive. I selected it and started installing Windows. I didn't even have to go into Bios and change anything there.

Company Asus in their socket motherboards 1155 provided the user with new opportunities to manage settings through the BIOS, presenting it using a graphical shell and the ability to change settings using the mouse. Let's see what has changed compared to the old way of presentation using pseudographics (text interface).

Motherboards were used in preparing this article ASUS P8P67 (LGA1155) And ASUS P8P67 Deluxe (LGA1155) .

EZ Mode

By default, the mode is enabled EZ Mode :

Several languages are supported, but Russian is not among them.

In case of operation in mode EZ Mode a fully graphical shell appears, in contrast to the normal mode, which is maximally compatible and understandable with previous BIOS versions from ASUS .
Everything is as simplified as possible - there are three performance presets and a load order manager.
All.

You can switch to advanced mode like this:

Main

The layout of the main BIOS elements is typical (Advanced Mode) - the names of the sections are at the top, and on the right side there are hints about what each section is responsible for and which keys are available for navigation.

The first section of the menu containing information about the BIOS version, processor, memory. You can select the language and set the system time.

In the Security subsection you can set a user password and an administrator password.

Ai Tweaker

This is the section responsible for overclocking and operating modes of the processor, memory and EPU power management system.

AI Overclock tuner — the option offers 3 overclocking options: Auto (automatic), Manual (manual), using the X.M.P. profile, where the processor and memory frequencies are set optimal to achieve the memory frequency specified in the profile).

Turbo Ratio sets the Turbo Boost operating mode of the processor.

Memory Frequency – selection of memory operating frequency.

EPU Power Saving Mode – enable the motherboard power saving mode...

..and selecting an energy saving option: minimum, average, maximum.

OC Tuner – system auto-acceleration function. Use with caution.

Subsection DRAM Timing Control is responsible for fine-tuning memory timings. The current timing values of installed memory modules are also displayed.

CPU Power Management – here we set the processor multiplication factor...

... enabling Intel SpeedStep technology (reducing processor voltage and frequency during inactivity) ...

... and enable or disable Turbo Boost mode.

Long Duration Power Limit allows you to override the maximum TDP of the processor for long-term operation. The maximum value indicated.
For example, for a processor Intel Core i5-2400 the base value is 95.

Long Duration Maintained — the maximum duration of the processor with TurboBoost technology enabled when the Long Duration Power Limit value is exceeded.

Short Duration Power Limit — second TDP limit — triggered when the value of the first limit is exceeded.
The operating time in this mode cannot be adjusted.
According to Intel specifications, it works up to 10 seconds.

Additional Turbo Voltage – maximum additional voltage supplied to the processor in Turbo Boost mode.

Primary Plane Current Limit — maximum current permissible for powering the processor (step 0.125A).

Subsection DIGI+ VRM allows for more precise adjustment of the processor power system on the motherboard.
These five profiles relate to Load-Line Calibration, which serves to compensate for core voltage drops when the processor load increases. In Regular mode, it works according to Intel specifications. The remaining profiles adjust the speed of response to voltage sags and are necessary for overclocking. The higher the value, the greater the overclocking can be achieved, but the heating of the processor and power elements of the motherboard will increase.

VRM Frequency – enable automatic or manual mode for controlling the VRM frequency of the processor power module.

VRM Fixed Frequency Mode - in manual mode, you can set the phase switching frequency of the VRM module. The adjustment range is from 300 to 500 kilohertz, in 10 kHz steps.

VRM Spread Spectrum — enable or disable Spread Spectrum mode for the VRM of the processor power module (not to be confused with Spread Spectrum for the processor!).

Phase Control — selection of the operating algorithm for the processor power phase control control unit.

Manual Adjustment – in manual control mode of the power phase switching algorithm, you can select one of four presets - from the conservative Regular to the fastest Ultra Fast.

These presets are related to Load-Line Calibration. In Regular mode it works according to Intel specifications. The remaining profiles adjust the speed of response to voltage sags and are necessary for overclocking. The higher the value, the greater overclocking can be achieved, but the heating of the processor and power elements of the motherboard will increase.

Duty Control - the module controls the control of components of each phase of the processor power supply (VRM).
Two positions are possible:
T.Probe - the module focuses on the optimal temperature conditions of VRM components.
Extreme - maintains optimal VRM phase balance.
We recommend leaving the value T.Probe.

CPU Current Capability - module for controlling the range of possible energy consumption by the processor. There are five positions in total - from 100 to 140%:
If you are overclocking your processor, it is better to choose a higher value.

CPU Voltage – select the processor supply voltage control mode (Offset or Manual).

Offset Mode Sign – determines the increment (+) / decrement (-) of the supply voltage offset value. In simple terms, increasing or decreasing the processor voltage depends on the voltage hardwired into the processor, which is an exact reference.

CPU Offset Voltage – sets the offset value (from 0.005V to 0.635V) of the voltage.

CPU Manual Voltage specify the processor supply voltage manually (from 0.800V to 1.990V in 0.005V increments).

DRAM Voltage – RAM voltage (from 1.20V to 2.20V in steps of 0.00625V).

VCCSA Voltage — supply voltage of the System Agent. Range: from 0.800V to 1.700V in steps of 0.00625V.

VCCID Voltage — supply voltage of the processor I/O system (ring bus). Range: from 0.800V to 1.700V in steps of 0.00625V.

CPU PLL Voltage – setting the voltage for synchronizing internal multipliers (Phase-Locked Loop - phase automatic frequency control) (from 1.2000V to 2.2000V in steps of 0.00625V).

PCH Voltage – south bridge voltage (from 0.8000V to 1.7000V in steps of 0.0100V)

DRAM DATA REF Voltage And DRAM CTRL REF Voltage set the multiplier for each memory module (from 0.3950x to 0.6300x in increments of 0.0050x).

CPU Spread Spectrum – when overclocking, it is better to disable this option to increase the stability of the system.

When you switch the Ai Overclock tuner to Manual mode, more parameters are available.

BCLK/PEG Frequency – setting the base frequency (from 80 to 300 MHz)
Due to the nature of the platform LGA 1155 , it is problematic to obtain a stable system with a reference frequency above 105 MHz.

Advanced

Advanced setup contains 7 subsections, each of which is described below.

CPU Configuration – it displays the current parameters of the processor and provides the ability to change them. One of them, CPU Ratio, provides the setting of the processor multiplication factor.

Intel Adaptive Thermal Monitor - if desired, you can disable monitoring of the thermal state of the processor using the internal control mechanism. We do not recommend doing this, since this functionality is responsible for the health of the processor.

Active Processor Cores – this option allows you to set the number of active processor cores.
May be useful for benchers.

Limit CPUID Maximum – the option should be disabled for “old” operating systems (Windows XP).

Execute Disable Bit – technology to protect your computer from hacker attacks and viruses. It is recommended to enable the option if the processor supports this technology.

Intel Virtualization Technology – required for hardware support for virtual machines (VMM).

Enhanced Intel SpeedStep Technology – a technology that allows the OS to dynamically change the processor supply voltage and core frequency depending on the load to reduce power consumption.

Turbo Mode – enable/disable Turbo Boost technology for Intel processors (increasing core frequency when the load increases).

CPU C1E , CPU C3 Report , CPU C6 Report “signal” the OS that the processor supports advanced power saving modes.
It is better to enable it to reduce processor power consumption when idle.

System Agent Configuration - allows you to set which video adapter will be initialized first (Initiate Graphic Adapter), perhaps something else will appear in the future.

PCH Configuration – also contains 1 option - High Precision Timer, which turns on/off the high precision event timer (HPET - High Precision Event Timer).

SATA Configuration – this subsection displays connected devices and allows you to set the operating mode of SATA ports (Disabled, IDE Mode, AHCI Mode, RAID Mode) and enable/disable S.M.A.R.T. checking. Very convenient display of which port each device is connected to, and which port it is on the motherboard (indicating the port color).

For each of the ports, you can enable hot plugging of the device - Hot Plug .

USB configuration – USB devices connected to the motherboard at the time of entering the BIOS are displayed here, and you can also enable/disable USB 2.0 and USB 3.0 controllers.

EHCI Hand-off (Enhanced Host Controller Interface) — Enable or disable advanced USB controller management. For compatibility with operating systems that do not support this function, it is disabled.

Onboard Devices Configuration – in this subsection it is possible to enable/disable various controllers available on the motherboard, as well as set their operating modes:
The first option enables/disables the HD audio controller.

Below you can set the specification for audio output to the front panel (HD, AC97), as well as which source to transmit “digital” audio to – SPDIF or HDMI.

Separately, you can enable/disable the USB 3.0 controller...

... and FireWire buses (IEEE-1394).

These options set the operating mode of the Marvell SATA controller (SATA 3.0).

The first option is responsible for enabling/disabling the network controller, and Realtek PXE OPROM is analogous to BootROM (OS boot over the network).

If you have a JMB controller (depending on the type, it supports SATA and IDE disk drives), it becomes possible to turn it on/off, as well as set operating modes:

If you need to load the OPROM of the Marvell controller when the system boots, enable this item.

The Display OptionRom in Post option allows you to “reduce” the amount of information displayed and thus the system will load a little faster.

If there are 2 network controllers on the motherboard, then 2 additional options appear - Intel Lan Controller and Intel PXE OPROM.

Serial Port Configuration – turns on/off the operation of the RS-232 serial port and you can change the address and interrupt of the port.

APM – subsection that determines the operation of the system after a power loss ( Restore AC Power loss ) and sources with which you can turn on your computer. They are typical, so the possible parameters are simply shown in the screenshots:

Monitor

A section in which the main monitored parameters of the processor, motherboard, fan speed, etc. are displayed.

CPU Q-Fan Control – allows control of the processor fan speed.

CPU Fan Speed Low Limit – sets the minimum controlled rotation speed of the processor fan.

CPU Fan Profile – provides the user with processor fan operating mode profiles.

You must first disable EFI in the BIOS (set the value to disabled), then set the boot priority from the floppy drive or from USB, as desired. that's all. I can’t explain it more precisely.

Answer from Vladimir Repyov[guru]
The Boot tab, "Boot Option" is responsible for organizing the order of boot devices. ASUS EFI BIOS will display how many devices there are, depending on how many are installed on this computer. Boot Override is a very useful menu that allows you to assign a one-time priority to the boot device. When you need to install an OS or scan your system for viruses using a LiveCD or USB flash drive. After confirming the device selection, the system will prompt you to save the changes and reboot. That is, install the device from which you will install the OS, then begin the installation.
