Launch csm is not available in bios. How to disable Secure Boot from Bios for UEFI help. Skidaemo nalashtuvannya bios

Whether you bought a PC or a laptop with a front-mounted operating system Windows system 8, and then you want to see and change, for example, "sim" or whatever version of Linux OS you have, then you have to blame these problems, through the secure boot system "Secure Boot".

Rozrobniki Microsoft during expansion the rest of the version Windows 8 is now fully supported by sixteen bit BIOS versions. Natomist system has become 100% crazy with the so-called UEFI BIOS, which can be a secure boot system “Secure Boot”.

The Secure Boot system is recognized for not allowing startup shkidlivih programs before the vanity operating system and the anti-virus program is valid.

Well, it’s a miracle system, but, through Secure Boot, it’s simply impossible to log in and install another operating system on the PC or software security, what can not digital signature. We will direct the simplest example. You bought new computer With Windows 8 installed in front of you and they tried to install it on a new one, or replace the "higher" OS Windows 7, or I would like Unix to be similar to the system. You can forget about it, the function of the safe enticement will not allow any kind of corruption. If you are not suitable for such a setting, then you will need to turn on Secure Boot in the UEFI BIOS in order to enter the login system and turn on the installation system.

The pickers of modern motherboards here deactivate this function even before they are completed with add-ons or they are sold. As Unix distributors of similar systems have already solved this problem in their operating systems by adding to them the UEFI BIOS security trick, then our colleagues from Microsoft should not be afraid to make changes to Windows Vista and Windows 7. And if those systems are corrupted by millions of people, then you know how to turn on Secure Boot is simply necessary to fully corrupt the PC.

Turning on Secure Boot is even simpler, for which you need to restart your PC and on the cob of your start-up, press the “Del” key once on the keyboard (you can use other options for the keys, for example, F8 or F2), to start the BIOS (introduction system).

We will not describe the process of enabling Secure Boot for all BIOSes (may be subject to the availability of software vendors). So it’s just not real, that and we can’t yet have such a possibility, so that under the hand were those mobile PCs of all virobniks. Let's say on the Pheonix SecureCore Tiano application, the BIOS is hacked practically on all laptops that are developed by Samsung, as well as for the Asus UEFI BIOS Utility.

• Enabled Secure Boot on Samsung laptops. Go to the BIOS at the Boot distribution. Find the Secure Boot option and set its value to "Disabled", then set the value to "UEFI and CSM OS" for the OS Mode Selection option. Ready. Now you can see Windows 8 from your Samsung laptop and install your new OS.
• Enabled Secure Boot Asus laptops. Select the UEFI partition “Boot”, then “Secure Boot”, then navigate to “Key Management” and change the value to “Crear Secure Boot Keys”. Done, intrusive function disabled.

CSM is the totality support module for the operating system. If your motherboard is secured with the BIOS (UEFI) retailers described above, then try to activate the Legacy BIOS function before the descriptions.

CSM stands for Compatibility Support Module for Operating System. In other BIOSes (UEFI), you may need to turn on the legacy option: Legacy BIOS. To blame installation problems, you can try switching the SATA controller to AHCI mode. How to fight is written in the article "Turn on ACHI support for SATA disks"

"Composter" bumped into thin materials, which will be eaten in the past three days. In the computer world, it is called sumism. The dopeful mind of the experimenter wants to know: what will you do if you don’t listen to your mother’s manual and act out of the mind? In other words: what is the best material for the implementation of the Clear CMOS operation on the motherboard? Like everything else, follow us, dear readers. We started experimenting with the Aptio Setup Utility, which was successfully introduced to the UEFI BIOS stock by American Megatrends.

Don't say GOP because you don't know how it ends

It's easy and simple with laptops: when you enter Setup, badioro stench reports that the GOP version is being supported on this platform. Guessing to the team who only recently joined us: Graphics Output Protocol- Price novelty, which came to change the VGA BIOS for UEFI.

Fig 1.CSM, as a technology of the mind,
curve additional options UEFI BIOS menu

Folding on the right with floor systems. At the expansion slot, you can practically insert a compatible video card. If we have a video card that does not have GOP support, but we have CSM-mode and we can see it from Setup by recording, then after reloading we check fatal pardon – beep about the duration of the video (1 long and three short beeps). Then a pause and then a sudden re-advancement, at some point BIOS notifying CSM on its own and ahead of us about such notifications:

The VGA Card is not supported by UEFI Driver.
CSM (Compatibility Support Module) settings have been changed for better compatibility.

What are the implications of the POST-procedures process? Obviously, since the VGA BIOS does not support UEFI, the system board firmware cannot interact with the resources of the video card using the GOP protocol. Ignore " unhandled» Legacy VGA BIOS and work with the video controller directly, the firmware of the motherboard also cannot, so the operations with the graphics controller require specific support and the UEFI BIOS of the motherboard is not ready to support all types of graphics controllers.

CSM - tse mist mizh minulim and probable

The only solution, accepting the summation of the old and the new, is the Compatibility Support Module technology. Just won't create "mistok" between UEFI GOP and Legacy VGA BIOS.

editing other CSM menu options

The algorithms of the Aptio Setup utility will win us over. Although CSM mode is enabled, all other options are available on this side. When mindfulness mode is disabled, other options become unavailable. If you want to exit Setup, saving the changes, the platform cannot initiate video and generate a pardon, as described above.

Obviously, the food is worth more than graphics. If we install, for example, a Storage-controller, firmware that does not support UEFI, then when the CSM mode is disabled, disks connected to a new one will become inaccessible.

Windows 8, however, is bound to have decal issues that prevent you from installing Windows 7 over Windows 8.

Problem 1:

Unfortunately, don't ever try to install Windows 7 on a storage device with a GPT-socket - some laptops simply don't allow you to install Windows 7 with UEFI-boot enabled. Do not hesitate to install Windows 7 on GPT disks from a non-original disk (for example, from a disk, deselected image with different editions of Windows 7), as well as from "non-UEFI" exciting flash drives(you can create a flash drive with UEFI zavantazhuvachem, but far from skin coristuvachevі chain pіd force). Therefore, it is easier to deactivate guessing (i) item (s) UEFI-boot (i/or Secure-boot) in BIOS maternity pay laptop or computer, and even Windows 7 can be installed without problems. Activating "UEFI-boot" allows you to set up a UEFI service partition on a GPT (GUID Partiton Table) storage device. Vidpovidno deactivation allows you to install Windows 7 on disks with an MBR socket.

Apply

I have custom BIOS you can come in from service menu Windows 8. You can spend some time in the new one for the help of a regular re-engagement from the pressed Shift key.

Problem 2:

At the command line:

• Type "diskpart" and press the "ENTER" key.
• Requested command diskpart type without paws: "list disk" and press the "ENTER" key.
• Write down the disk number that you want to convert to an MBR disk.
• For the requested diskpart command, type without paws: "select disk (de - disk number) and press the "ENTER" key.
• Type the "clean" command to clean the disk and remove all partitions
• When requested on diskpart, type without paws: "convert mbr" and press the "ENTER" key.

Dodatkovo about installed Windows 8:

Have a nice day.

Dosit often richly koristuvachіv set the power supply to Secure Boot (for example, this option is necessary to enable Windows installations). If you do not turn it on, then this function is required (decommissioned by Microsoft in 2012) keys, yaki є less in Windows 8 (i more). Obviously, you can’t take a laptop with any kind of wear ...

In this small article, I want to look at a few popular brands of laptops (Acer, Asus, Dell, HP) and show them on the example, how to turn on Secure Boot.

Important note! To enable Secure Boot, you need to go into the BIOS - and for which you need to press the appropriate buttons as soon as the laptop is turned on. One of my articles is dedicated to this food. It has a button for various options and it is reported how to get to the BIOS. Therefore, in this article, I will not dwell on which food.

Acer

(Screenshots from the Aspire V3-111P BIOS)

Once you have entered the BIOS, you need to open the "BOOT" tab and see that the "Secure Boot" tab is active. Shvidshe for everything, she will be inactive and її you will not be able to change. This is done through those that have not set the administrator password in the BIOS Security section.

To install it, next open it and select Set Supervisor Password and press Enter.

Well, after that you can open Boot - the Secure Boot tab will be active and you can switch it to Disabled (to disable it, see screenshot below).

After restarting the laptop, the wine is guilty of trying to get some extravagant outbuilding (for example, from flash drives with Windows 7).

Asus

Some models of Asus laptops (especially new ones) should be set up for an hour at a deaf corner. Really, how can you turn on the protection of the interest?

1. At the beginning, we go into the BIOS and open the "Security" section. At the very bottom there will be an item "Secure Boot Control" - you need to switch it to disabled, then. turn it down.

2. After the reboot, I will see the BIOS again and then at the “Boot” branch, start working again:

• Fast Boot - translate into Disabled mode (tobto enable shvidke zavantazhennya. Tab є do not scrape! If you don’t have any - just skip this recommendation);
• Launch CSM - switch to the Enabled mode (to enable support and summation with the "old" OS and firmware);
• Let's sweat again F10- Take care of repairing and re-adjusting the laptop.

3. After the reboot, enter the BIOS and open the “Boot” section - at the “Boot Option” item, you can select a new option, which will connect to USB port(for example). Screenshot below.

Let's save the BIOS settings and reboot the laptop (F10 button).

Dell

(Screenshots from Dell Inspiron 15 3000 Series laptop)

Dell laptops have Secure Boot enabled, without a doubt, one of the simplest is to get one entry into Bios and not need the same passwords for administrators and others.

After entering the BIOS - open the "Boot" section and set the next parameters:

• Boot List Option - Legacy
• Security Boot - disabled (includes security protection).

Vlasne, far away, you can draw a line of entanglement. More install new Windows OS exciting USB flash drive - that’s why I bring a screenshot below, which row you need to put on the top, so you can zavantazhitsya from a flash drive ( USB Storage Device).

After entering, press the button F10- you will save the entered settings, and then the button Esc- no problem, you will exit the BIOS and reboot the laptop. Vlasne, on whom the inclusion of the stolen zankazhennia on the Dell laptop is completed!

HP

After entering the BIOS, open the System Configuration section, and then go to the Boot Option tab (div. screenshot below).

After reloading, the text "A change to the operating system secure boot mode is pending ..." appears.

We are warned about making changes to the installation and confirming them with the code. Just need to enter the code, the indications on the screen and press Enter.

After that, change the laptop to re-advantage, and secure boot you will be slammed.

To get started from a flash drive or a disk: when you click on the HP laptop, click on ESC, and select the “F9 Boot Device Options” item from the start menu, then you can select the attachments you want to get excited about.

In principle, laptops of other brands have secure boot pass similarly, there are no special powers. A single moment: on some models, the BIOS entry is “complicated” (for example, on laptops Lenovo- You can read about it in these articles:). I’ll round off on what, we’ll have a good one!
