How to delete grub from windows

Загрузчик Grub — это загрузчик, который используется по умолчанию в большинстве дистрибутивов Linux. Grub расшифровывается как GRand Unified Bootloader, он поддерживает загрузку не только Linux, но и Widnows, и DOS.

Если вы устанавливали Linux, а потом по каким-либо причинам решили его удалить и вернуть Windows или создали загрузочную флешку Linux, но теперь она вам больше не нужна, нужно удалить загрузчик Grub. В этой инструкции мы рассмотрим, как удалить загрузчик Grub из MBR или из UEFI, также поговорим о том, как удалить Grub с флешки.

Как удалить загрузчик Grub и восстановить Windows

Если на вашем компьютере установлено две операционные системы, Windows и Linux, и вы хотите стереть Linux и его загрузчик, восстановив загрузчик Widows, и у вас используется таблица MBR, то это сделать очень просто.

В сети часто советуют способ: взять установочный диск Windows, загрузиться с него в режиме восстановления и выполнить команды:

bootrec \fixboot

bootec \fixmbr

Это действительно ответ на вопрос «как удалить Grub и восстановить загрузчик Windows?», и он работает. Но есть способ намного проще. Вам даже не придётся перезагружать компьютер. Утилита Bootice позволяет восстановить загрузчик Windows и удалить Grub с жёсткого диска в несколько кликов.

Скачать утилиту можно с softpedia, потому что на официальном сайте всё по-китайски. Только выберите правильную разрядность для своей системы. Запустите утилиту, выделите диск, на котором у вас установлен загрузчик Grub, затем нажмите кнопку Proccess MBR:

И готово: вы смогли успешно полностью удалить загрузчик Grub. Можете перезагружаться и проверять.

Как удалить загрузчик Grub в UEFI

Эта проблема тоже решается с помощью утилиты Bootice. Только на это раз вам нужна именно 64-битная версия программы.

Одно из преимуществ UEFI на MBR в том, что здесь можно устанавливать сразу несколько загрузчиков на специальный раздел. Для удаления загрузчика Grub и восстановления функциональности Windows достаточно переместить Grub чуть ниже в очереди загрузки UEFI.

Картинка с сайта: losst.pro

Откройте программу, перейдите на вкладку UEFI и нажмите Edit Boot Enteries. Откроется такое окно:

Здесь у вас есть два варианта действий. Либо опустить Grub ниже загрузчика Widnows кнопкой Down, либо полностью удалить запись о загрузчике кнопкой Del. Но в обоих случаях файлы загрузчика останутся на диске. Полностью удалить загрузчик Grub со всеми его файлами нужно из командной строки. Это немного сложный процесс, но всё же мы его разберём.

Кликните в левом нижнем углу экрана правой кнопкой мыши, в открывшемся контекстном меню выберите Командная строка от имени администратора.

Далее нам понадобится утилита diskpart, все действия мы выполним с помощью неё. Запустите её командой:

diskpart

Затем смотрим доступные диски:

list disk

И выбираем наш единственный диск, на котором сейчас установлена Windows, а раньше была установлена Ubuntu:

sel disk 0

Картинка с сайта: losst.pro

После того, как был выбран диск, мы можем посмотреть список разделов на нём:

list vol

Картинка с сайта: losst.pro

Среди этих разделов есть и раздел с файлами EFI, для обычной системы он скрыт, но не для этой утилиты. В нашем случае это Volume 2. Как правило, это небольшой раздел с файловой системой FAT32 и отмеченный как системный.

Мы выбрали этот раздел текущим с помощью команды:

sel vol 2

Затем назначим ему букву, чтобы можно было с ним работать:

assign letter=E:

Утилиту можно закрывать. Дальше продолжаем выполнять действия в консоли. Сделать всё с помощью проводника вы не сможете, потому что нужны права администратора. Переходим на диск E:

cd \d E:

Переходим в папку EFI:

cd  EFI

Удаляем папку с файлами загрузчика Ubuntu:

rmdir \S ubuntu

Картинка с сайта: losst.pro

Готово: удаление загрузчика Grub завершено, и теперь его файлов больше нет в системе.

На флешках, как правило, используется таблица разделов MBR. Чтобы удалить загрузчик Grub с флешки недостаточно просто её отформатировать. Загрузчик записывается в таблицу MBR, а поэтому нам придётся её пересоздать. Очень не рекомендую использовать этот способ для удаления загрузчика Grub с жёсткого диска, потому что вы потеряете все данные.

Работать будем в системе Linux. Сначала посмотрите, какое имя устройства у вашей флешки, например, с помощью программы Gparted или в терминале командой:

fdisk -l 

Затем удалим полностью существующую таблицу разделов:

dd if=/dev/zero of=/dev/sdc count=512

Теперь, с помощью той же Gparted создаём новую таблицу разделов:

Картинка с сайта: losst.pro

Создаём раздел на флешке и форматируем в файловую систему FAT32:

Картинка с сайта: losst.pro

Теперь вы знаете, как удалить MBR с флешки, только не сотрите его с жёсткого диска, потому что потом будет сложно восстанавливать.

Выводы

Я не знаю, зачем вам понадобилось удалять Linux. Это отличная операционная система, правда ещё остаётся оборудование, которое она не поддерживает или поддерживает не полностью. Не сдавайтесь быстро: если Linux не работает на одном устройстве, то, возможно, в будущем у вас появится другой компьютер или ядро начнёт поддерживать ваш ноутбук. Пробуйте и экспериментируйте. Во всяком случае теперь вы знаете, как удалить Grub с жёсткого диска. Если остались вопросы — задавайте в комментариях.

     bootrec /rebuildbcd

   • Explanation of Commands:
     • bootrec /fixmbr: This command writes a new Master Boot Record (MBR) to the system partition, effectively eliminating GRUB.
     • bootrec /fixboot: This attempts to write a new boot sector onto the system partition.
     • bootrec /scanos: This scans for all installed operating systems.
     • bootrec /rebuildbcd: This command rebuilds the Boot Configuration Data (BCD).

3. Restart Your Computer:

   • After executing all commands, restart your PC. You should now boot directly into Windows.

Method 2: Utilizing Windows Recovery Environment

If issues arise during the Command Prompt method or if you cannot access the command line, you can utilize the Windows Recovery Environment (WinRE).

1. Accessing WinRE:

   • You can access WinRE by booting from a Windows installation media or using the recovery drive you created earlier. If you don’t have one, you can create a Windows 11 installation media using Microsoft’s media creation tool.
   • Boot from the USB drive and select «Repair your computer» instead of «Install now.»

2. Navigating to Command Prompt:

   • Select «Troubleshoot,» then «Advanced options,» and finally «Command Prompt.»

3. Execute Bootrec Commands:

   • Input the same bootrec commands as mentioned earlier:

     bootrec /fixmbr
     bootrec /fixboot
     bootrec /scanos
     bootrec /rebuildbcd

4. Complete the Process:

   • After executing the commands, exit the Command Prompt and return to the previous screen. Choose «Turn Off Your PC» and then turn it back on to check if Windows starts normally.
