Windows won't boot after updating BIOS. After updating the BIOS, Windows does not boot on the laptop. How to fix the All boot options are tried error? Faulty blocks in the computer

BIOS is the Basic Input/Output System, the heart of the computer, without which the normal operation of other components and software is impossible. When you turn on your computer, the BIOS starts first and only after you turn it on, the operating system starts loading.

Theoretically, since Windows boots after the BIOS, reinstalling the operating system or adding another OS should not affect the normal operation of the BIOS. However, there are often cases when an attempt to install a second operating system results in the BIOS not loading.

In this case, we can assume that the BIOS settings have gone wrong and restoring the default settings may solve the problem. To reset the settings, you need to perform the following operations.

Disconnect the PC and monitor from the electrical network.
Open the system unit and remove the battery from the motherboard.
Wait a few minutes.
Return the system battery to its place.
Connect power to the computer and monitor.

After restarting, the BIOS will start loading “like the first time”. If the problem goes away after this, it is recommended to format the boot hard drive and reinstall the operating system. Preferably one that has previously worked without problems. It is quite possible that the added operating system was damaged in the distribution.

Connection problems

There is a high probability that the BIOS does not load due to breaks in the power supply networks or data loops. To check this option, you first need to listen to see if the cooler on the motherboard is spinning. The BIOS is part of the processor and therefore poor cooling of the motherboard leads to malfunctions.

Perhaps the contact groups of the fan have come loose, which is why it does not work. After this, carefully inspect all cable and cable connections. Check to see if dust has accumulated on the motherboard or contacts. Dust is an excellent conductor of electric current, and it also creates electrostatic fields, to which electronics are very sensitive.

Clean the device from dust using a vacuum cleaner and a brush.
Sequentially disconnect the contactors and clean the terminals from dirt and oxidation. You can use a school eraser to clean the contacts.
Check that all connectors are securely attached. It is likely that vibration caused the contacts to separate, and therefore the equipment stopped working correctly.

After the maintenance, you can try to start the computer again. The screen is black again and the BIOS won't load? Then we can assume that one of the internal modules is faulty. Including the motherboard itself could fail or need to be reflashed.

You can download the new firmware for the motherboard on the manufacturer’s official website. Updating the firmware is a difficult and quite risky task. Therefore, if you don’t know exactly what and how to do, it’s better not to take risks, otherwise you could ruin your entire computer, including the hard drives. It is better to contact the service center.

Faulty blocks in the computer

None of the above helped? Then the likelihood of hardware failure increases and you can start checking the blocks.
Disconnect and remove anything from the device that is not necessary for the computer to start. Leave only the motherboard, power supply and one of the RAM sticks. The computer will not work in this state, but it is possible to check the serviceability of the motherboard itself.
A common reason for the inability to start a computer is insufficient power from the power supply. For example, you replaced the motherboard with a more advanced one, which requires more electricity. However, the power supply remains old. Or so - additional hard drives or some other functional components were installed in the system unit. Energy consumption can increase quite significantly. Installing a more powerful power supply will solve the problem. If the issue, of course, is a lack of energy.

Often, loading the BIOS is prevented by a malfunction in the video card. If possible, you need to check the video card by replacing it with another similar one. Or install the video card in another computer. Here you need to look at the compatibility of the equipment. Otherwise, you won’t find the problem, but you may create new problems.

If the minimum configuration - motherboard, power supply, RAM socket - the system unit is working and the BIOS is loading, then the problem is in one of the removed modules. After installing and connecting the next unit, try turning on the computer again and see what happens. As soon as the BIOS stops starting again, we can assume that you have discovered a faulty unit. Now all that remains is to find a similar one and replace it.

In reality, everything often turns out to be much more complicated. For example, the computer sometimes boots and works quite normally, and then, for no apparent reason, it starts to fail. The problem can be either software or component failures.

Such periods of normal operation, alternating with the inability to load the BIOS, are typical for three types of problems.

Presence of microcracks on the motherboard. Because of this, contact periodically disappears.
The electrolytic capacitors on the motherboard or power supply have dried out. This malfunction mainly applies to old system units that have been in use for a long time. Sometimes faulty capacitors can be identified by characteristic swelling of the housing.

Poor contact in the connected wires. As already mentioned - the presence of dust, oxidation of contacts, insufficient pressure. If the contactors have fixing screws, they must be tightened completely. The opposite situation also happens - clamping screws that are tightened too tightly lead to deformation of the connectors and poor contact in the connection.

Sometimes when loading the tenth version of the operating system in various situations, the INACCESSIBLE_BOOT_DEVICE error may pop up. It can appear after resetting the operating system, updating the BIOS, connecting another hard drive or solid-state drive, adjusting the structure of departments on the drive, and in many other moments. There is a similar error where a blue screen appears saying NTFS_FILE_SYSTEM. It can be eliminated using the same methods.

First of all, before trying to resolve the error by any means, you need to perform a few simple manipulations. Initially, you need to remove all third-party drives from the computer. In addition, it is worth checking the loading order of the drives. It is necessary that the system drive be in the first position. To do this, you need to go to BIOS or UEFI. It is worth noting that in UEFI it may not be the first hard drive, but the Boot Manager item. After this you need to restart your computer.

In addition, if something was connected to the computer, cleaning was carried out, or any similar manipulations were performed inside the computer, it is necessary to check the correctness and reliability of all connections of the hard drive or solid-state drive with power and SATA ports. In some cases, connecting to another SATA port helps fix the error.

INACCESSIBLE_BOOT_DEVICE after resetting the operating system or installing updates

In addition, there is another fairly simple option for eliminating the error that appears after resetting the operating system to factory settings or after installing Windows updates.

In this case, you can use a very simple option to resolve the error. On the screen with the words “PC started incorrectly” that appears immediately after the notification with the entered text after resetting the error data, you need to click on “Advanced options”.

In the window that appears, you must select “Troubleshooting and troubleshooting.” In this section, you need to click on “Boot Options”, after which you need to click on the “Restart” button. As a result, the computer will restart and a prompt will pop up to boot the PC in different options. Here you need to specify option 4, which requires pressing the F4 button, after which the PC will boot into safe mode.

After the PC starts in the selected mode, you need to reboot it again. To do this, go to “Start”, select the “Shut down” button, and then click “Restart”. If this problem occurs, this method helps in most cases.

In addition, in the additional settings of the recovery environment there should be a “Startup Recovery” item. For unknown reasons, in the tenth version of Windows, you can use it to fix startup-related problems, and quite complex ones at that. It is recommended to try this option if the above does not help.

Windows 10 won't boot after BIOS update or power failure

There is also another fairly common reason for the “ten” loading error, INACCESSIBLE_BOOT_DEVICE. In this case, the BIOS settings that relate to the operating mode of SATA drives are lost. In most cases, this error occurs during a power outage or after a BIOS update is completed. In addition, this can occur when the battery on the motherboard dies. As a result, the parameters are reset.

If there is an assumption that this is why the error occurs, then you need to go to the BIOS of your computer or laptop. After this, you need to go into the parameters of SATA devices and try to change the operating mode. If the settings are set to IDE, you need to activate AHCI or vice versa. Then you need to save the BIOS settings and restart the PC.

The disk is faulty or the partition structure on the drive has changed

An error like this means that the OS loader did not detect and did not gain access to the system disk. This can happen due to problems in the file system or mechanical problems with the drive. In addition, adjusting the structure of disk sections can affect the appearance of the error.

In any case, the download must be performed in the operating system recovery environment. If you can open Advanced Options after the error window, you need to run them.

If this is not possible, then you should resort to using an installation drive with an operating system to open the recovery environment. Such a drive can be created on another PC.

In this environment, you need to go to Troubleshooting. After this, you need to go to “Advanced options”. In this window you need to select “Command Prompt”. Then you need to find out the letter of the system department, which may not be S.

In this case, you must enter diskpart. After this you need to write list volume. Here you need to find and remember the name of the OS volume, which will be the volume letter. In addition, you need to remember the name of the partition with the bootloader; it may be useful in the future. This field must be entered exit.

To check the disk for damage, you need to enter the command chkdsk C: /r and then press Enter. Next you need to wait until the command completes. If errors are identified during the process, they will be automatically corrected.

In addition, there is an option in which there is an assumption that this error may occur after user manipulations in manufacturing and adjustment of drive sections. In this case, you need to register bcdboot.exe C:\Windows /s E:. Here C is the department with the operating system, and E is the department with the bootloader. After that
Once the command is completed, you need to restart the PC in standard mode.

If nothing helps fix the problem

If none of the above has brought the desired result and the operating system still does not load, then only reinstalling the system can help. You can also perform a reset using the boot drive. To reset in this case, you need to do some manipulations.

First of all, you need to boot from the drive with the operating system, and the version that is installed on the PC. A language selection screen will then appear, followed by the Install button. On this screen you need to select "System Restore".

Clicking on the link will open the recovery environment in which you need to click on “Troubleshooting”. On this screen you need to click “Reset PC”. After this, recommendations are required on the screen.

It happens that if this error occurs due to problems with the hard drive or its partitions, then if you need to roll back the operating system and save the data on it, a message may pop up that this is impossible and the information must be deleted.
If the information on the disk is important, you need to save it somewhere, for example, overwrite it on another computer or boot from a Live drive.

Here, in principle, are all the reasons and methods for eliminating the Windows boot error INACCESSIBLE_BOOT_DEVICE.

Sometimes after some laptop models stop loading the operating system. Instead, when turned on, they immediately automatically enter the BIOS. There, if you look at the boot list (), you will notice that it is empty. That is, it does not have a hard drive, DVD drive, or bootable flash drive that you could insert into a USB port. Although they are all connected and can even be displayed in the BIOS among the connected devices.

What to do in this situation and how to return the laptop to working condition yourself at home?

Why is this happening?

In most cases, this situation occurs, as mentioned above, after resetting the BIOS settings. Moreover, it is not necessary to do this through the corresponding menu. It is enough to remove the battery from the laptop for a few minutes and disconnect it from the electrical network. Updating the BIOS and removing dust also often leads to its reset.

In some versions of laptops, especially after 2016, the BIOS contains various options, the incorrect installation of which will prohibit booting from a hard drive or flash drive. Therefore, when turned on, the laptop itself enters the BIOS, since it does not see a single device from which it could continue booting.

How to fix this situation?

To do this, in the BIOS settings that appear on the screen immediately after turning on the laptop, you need to find the option and disable it, that is, set it to the Disabled state. It may have a slightly different name, such as Fast Boot, and is usually located on the Advanced or Boot tab. On Asus laptops with UEFI, you need to press F7 in the main window to activate advanced mode.

Fast Boot Option

As soon as you have disabled Fast Boot, immediately save the settings with the F10 button, then restart the laptop and go into the BIOS again.

Next, on the Boot or Security tab (possibly in our case on other tabs), you need to find the option and also disable it by moving it to the Disabled state, and the UEFI and Legacy OS (CSM - Compatibility Support Module) (OS Mode Selection) parameter should be set to CMS OS or Other OS or Legacy.

Secure Boot Option

OS Mode Selection Option

Now we save the settings using the same F10 button, reboot and check. The laptop should start loading Windows.

If this does not happen, then try to find the Legacy Support option in the BIOS and set it to Enabled. Also, if there is a parameter

Preview. This material was prepared after trial operation of a 13-inch ultrabook Samsung NP530-U3C, however, this problem can also be encountered on other models of the Korean manufacturer. If your Samsung laptop does not work after updating the BIOS, that is, when you turn it on, you only see a black screen with an error All boot options are tried..., then this article is for you.

The complete error message looks like this:

All boot options are tried. Press key to recover with factory image using Recovery or any other keys for next boot loop iteration.

The reason for this error is the BIOS update. An ordinary user would never think of such a thought in his life, but Samsung laptops have a proprietary utility installed SW Update, which itself offers this procedure. Since this is a proprietary utility, many people confidently update everything. When it comes to the BIOS, suddenly it turns out that something has gone wrong.

If the All boot options are tried error appears on your screen, press any button to go to the BIOS.

In the BIOS go to the tab Boot and set the following settings:
Secure Boot - Disabled
OS Mode Selection - UEFI and CSM OS

Save the changes and exit the BIOS. After this, the All boot options are tried error in the laptop will disappear and the installed Windows 8 or 7 OS will start.
