2. In command prompt type the following command to list all the drives on your system:
- wmic logicaldisk get name
3. Now, by using the «DIR <Drive_Letter>» command, examine the contents of all listed drives (except the drive X:), to find out which drive contains the «Windows» folder. (e.g. «dir C:») *
- dir C:
* Note: If the Windows directory is displayed then continue to the next step. otherwise continue by typing the next alphabet letter until you found which drive contains the Windows folder (e.g. dir d: , dir e:. dir f:, etc.).
(In this example the Windows folder is located at drive C: )
4. Then open the DISKPART utility by typing the following command and press Enter:
- diskpart
5. At DISKPART prompt type:
- list disk
6. Now type the following command and then press Enter:
- select disk X
* Note: Where «X«= the number of the disk where you install the Operating System. (e.g. the disk 0 in this example).
7. Then type the following command and press Enter.
- list partition
8. Find out which Partition is labeled as System.
(In this screenshot the Partition 4 is labeled as System)
9. Select the System partition by typing:
- select partition X (Where «X «is the number of the partition labeled as System. e.g. «4»).
10. Assign a drive letter (e.g. the letter «S«) to the System partition by typing the following command and press Enter: *
- assign letter=S:
* Note: If the drive letter «S» is already used, then give the next drive letter in alphabet.
11. Type exit and press Enter to close DISKPART tool.
12. Then give the following commands in order (press Enter after typing each one of them).
-
- cd /d S:\EFI\Microsoft\Boot\
- ren BCD BCD.bak
- bcdboot C:\Windows /l en-us /s S: /f UEFI
Notes:
1. Change the letter «S» if you have assigned a different drive letter to the System partition.
2. If Windows is located on a different drive then use that drive letter instead of «C«.
3. The «/l en-us» part of the above command sets the Windows language to English. If you want to set a different language, then replace the «en-us» with the appropriate language code (e.g. «fr-FR» for France).
13. When the command is executed, press the Power button for 5-6 seconds to fully shutdown the PC.
14. Unplug the USB media.
15. Power ON the PC to finish the Windows 10 installation.

This error occurs when users try to update their Windows installation from an older version of Windows or when performing an in-place update using the Windows Media Creator on a USB or a DVD. It’s quite a common error which appears during Windows Setup and it annoys the hell out of users.
There have been registered quite a few useful methods which can help you resolve the problem and continue through the setup normally. Follow the solutions we have prepared below carefully!
What Causes the “Windows could not update the computer’s boot configuration” Error?
The error is often associated with the broken Boot manager utility which handles how your computer boots and what to load with priority. This can be solved by resetting it completely.
In other cases, it’s UEFI which prevents the Windows setup from loading properly so you should disable secure boot in BIOS.
Finally, the problem may be with your partition. If you are performing a clean install, please make sure you try to clean it with diskpart.
Solution 1: Repair the Boot Manager in Command Prompt
The Boot Manager is used to manage how your system boots, the boot priority, and how it handles Windows installation media when you insert it during startup. It can be reset and repaired easily if you simply restart into Advanced Startup and run several useful commands, which will be presented below.
- If your computer’s system is down, you will have to use the installation media used to install windows for this processInsert the installation drive you own or which you have just created and boot your computer. The following steps are different from one operating system to another so follow them accordingly:
- WINDOWS XP, VISTA, 7: Windows Setup should open prompting you to enter the preferred language and time and date settings. Enter them correctly and choose the Repair your computer option at the bottom of the window. Keep the initial radio button selected when prompted with Use recovery tools or Restore your computer and click on the Next option. Choose Startup Repair (the first option) when prompted with the Choose a recovery tool selection.
- WINDOWS 8, 8.1, 10: You will see a Choose your keyboard layout window so choose the one you want to use. The Choose an option screen will appear so navigate to Troubleshoot >> Advanced Options >> Command Prompt
- If you are not having problems with the system, you can use the Windows UI to access this screen. If you are using Windows 10 on your PC, there is another way to access Safe Mode on your computer. Use the Windows Key + I key combination in order to open Settings or click the Start menu and click the gear key at the bottom left part.

bootrec /RebuildBcd bootrec /fixMbr bootrec /fixboot
- Close Command Prompt afterwards and choose the Restart option. Check to see if the problem is gone.
Solution 2: Disable UEFI in BIOS
There are several options you might want to change in your BIOS settings in order to enable the Windows Setup to install properly. The first option is called Secure Boot which uses UEFI. This prevents the proper installation. Besides that you should enable Legacy Support or Legacy Boot and set it to enabled.
- Turn on your computer and immediately press the BIOS Setup key on your keyboard several times in a row, about once every second, until the Computer Setup Utility or BIOS settings opens. This key will be indicated on your screen as Press _ to run Setup.
- Use the right arrow key to switch to the Security menu when the BIOS settings window opens, use the down arrow key to select the Secure Boot Configuration from the menu, and press Enter. These options are sometimes location under System Configuration or the Security tab
- Before you can use this option, a warning will appear. Press F10 to continue to the Secure Boot Configuration menu. Use the down arrow key to select Secure Boot and use the right arrow key to modify this setting to Disable.
- Use the down arrow key to select Legacy Support, and then use the right arrow key to switch it to Enable.

- The Computer Setup Utility will now shut down and the computer should restart. When the computer has restarted, keep following the steps below to solve the VAC authentication error.
Solution 3: Use the Clean Option in DiskPart
This method is a sort of a last resort for users who are performing a clean installation. This consists of cleaning the partition where you tend to install Windows. This is only recommended for clean installs, meaning you should backup the data from the partition. This should be enough to solve the problem but be careful to select the proper partition based on its number.
- Open Command Prompt using the steps provided in Solution 1.
- At this command prompt window, type in simply “diskpart” in a new line and click the Enter key in order to run this command.
- This will change the Command Prompt window to enable you to run various Diskpart commands. The first one you will run is the one which will enable you to see the complete list of all available disks.
DISKPART> list disk
- Make sure you choose your disk carefully, depending on which number is assigned to it in the list of volumes. Let’s say that its number is 1. Now run the following command in order to select disk.
DISKPART> select disk 1
- A message should appear saying something like “Partition 1 is the selected volume”.
Note: If you are unsure about which partition to select, the best way to do so is to check the actual size!
- In order to clean this volume, all you need to do is to type in the command displayed below, click the Enter key afterwards, and stay patient for the process to complete. This will also create an empty primary partition and add it to the top and the last command will exit Command Prompt.
Clean Create Partition Primary Exit
- Exit Command Prompt, restart your computer, run the Windows Setup again and check to see if the Windows could not update the computer’s boot configuration error still appears.

Может образ Винды для GPT? Он не встанет на MBR. Нужно в рабочий комп (например) поставить и посмотреть, к.о. размечен диск. Посмотреть, для какого типа сам образ Винды. Если образ для GPT, а диск MBR, его нужно преобразовать в GPT (например, в «Управлении дисками» Винды).

Исследователь обнаружил уязвимость в PyTorch, фреймворке машинного обучения с открытым исходным кодом. Уязвимость, зарегистрированная под номером CVE-2025-32434, относится к классу Remote Code Execution (RCE) и имеет рейтинг 9,3 по шкале CVSS, то есть категорируется как критическая. Эксплуатация CVE-2025-32434 при определенных условиях позволяет злоумышленнику запускать на компьютере жертвы, скачивающей ИИ-модель произвольный код. Всем, кто использует PyTorch для работы с нейросетями, рекомендуется как можно скорее обновить фреймворк до последней версии.
Суть уязвимости CVE-2025-32434
Фреймворк PyTorch, помимо всего прочего, позволяет сохранять уже обученные модели в файл, который хранит веса связей. И, разумеется, загружать их при помощи функции torch.load(). Обученные модели часто выкладываются в общий доступ через разнообразные публичные репозитории и теоретически в них могут быть вредоносные закладки. Поэтому официальная документация проекта в целях безопасности рекомендует использовать функцию torch.load() с параметром weights_only=True (в таком случае загружаются только примитивные типы данных: словари, тензоры, списки, и так далее).
Уязвимость CVE-2025-32434 заключается в некорректно реализованном механизме десериализации при загрузке модели. Обнаруживший ее исследователь продемонстрировал, что атакующий может создать файл модели таким способом, что параметр weights_only=True приведет к прямо противоположному эффекту — при загрузке будет выполнен произвольный код, способный скомпрометировать среду, в котором запускается модель.
