Grub — это программное обеспечение, которое позволяет выбрать операционную систему, которую нужно запустить при загрузке компьютера. В этой статье мы расскажем о пошаговой установке Grub из-под Windows, начиная с самого начала и заканчивая успешным запуском.
Шаг 1: Скачайте образ Grub
Первым шагом необходимо скачать образ Grub. Для этого перейдите на официальный сайт проекта и загрузите последнюю версию Grub.
Шаг 2: Скачайте EasyBCD
EasyBCD — это утилита для Windows, которая позволяет управлять загрузочным меню. Скачайте ее с официального сайта и установите на свой компьютер.
Шаг 3: Создайте раздел
Создайте новый раздел на своем жестком диске. Для этого можно воспользоваться утилитами Windows, например, «Управление дисками». Обязательно запомните букву диска, на котором создан новый раздел.
Шаг 4: Запишите образ Grub на раздел
Для записи образа Grub на раздел следует воспользоваться командной строкой, которую можно открыть в режиме администратора. Перейдите в папку, где сохранен образ Grub, используя команду cd. Убедитесь, что путь в консоли отображает текущую директорию с образом Grub.
Затем используйте следующую команду для записи образа Grub на раздел:
dd if=имя_образа_grub of=диск_с_разделом bs=512 count=1
Замените имя образа Grub и диск с разделом на соответствующие значения. Например, dd if=grub.iso of=E: bs=512 count=1
Шаг 5: Добавьте запись в загрузчик Windows
Запустите EasyBCD и выберите «Добавить новую запись». Затем выберите тип записи «Linux/BSD» и введите имя для новой записи.
В разделе «Путь к файлу» укажите букву диска, на котором создан новый раздел, и путь к файлу boot\grub\stage1.
В разделе «Привод/Сектор» укажите букву диска, на котором создан новый раздел, и номер сектора, где записан Grub. Например, 0x8001 для сектора 1 в байтах.
Сохраните новую запись.
Шаг 6: Запустите Grub
Перезагрузите компьютер и выберите новую запись в загрузочном меню. Grub должен успешно загрузиться.
Заключение
В этой статье мы рассмотрели пошаговую инструкцию по установке Grub из-под Windows. Надеемся, что она поможет вам успешно настроить загрузку операционных систем на вашем компьютере.

Касательно Debian, было бы интересно узнать, как его установить в среде Windows Если я не ошибся, в windows 10 с этим может помочь PowerShell(по крайней мере эмуляция linx у меня отрабатывала отлично, а эмуляцией ubuntu ставлю прошивки Padavan ) ну или виртуалка с пробросом порта с usb устройства. Пишут, что grub-2.02-for-windows не поддерживает UEFI enabled Secure Boot Если я не ошибся тут на форуме был такой метод UTmake — не китайская доработка (или у китайцев другое название?) Нет, я не знал про 0 сектора, про программу пока ничего не скажу . Флешка. Тут уже ответили. Все сборки разместить на FAT32, на раздел NTFS — только сборки с VHD и большие файлы. |
да и не у всех есть деньги\потребности. А флешки сейчас то же разные . Но я вас понял. буду ковырять дальше

SITUATION WHEN GRUB FILES AND BOOT SECTOR ARE NOT THE SAME PARTITION
Problematic solution
TODO EXPLAIN THE USE OF LIVESWAP WHEN DETECTED HARD DISK ORDER IS NOT OK.
GRUB solution (on its own)
This method is only valid when you want to boot a Linux partition that it is found in the same hard disk as the windows one (i.e. the first hard disk).
This installs Stage1 of Grub to the first sector of partition containing the Grub folder.
To get started we need to identify the partition containing the Grub folder. (Usually the same as the Linux partition) Say it is (hd0,3) (Usually, but not always, identified in Linux as: /dev/sda4).
Boot with your grub disk or with your already installed grub.
Press ‘c’
At the grub> prompt type:
- root (hd0,3)
- setup (hd0,3)
- quit #(With Linux working)
- reboot #(From grub disk)
Please continue reading at: Common Final Solution
GRUB solution (Linux shell)
This installs Stage1 of Grub to the first sector of partition containing the Grub folder. We will use the «device» function of the grub-shell to ensure that Grub uses the correct map between the bios drives and linux devices, and also to ensure that Grub uses the hard drive numbers.
To get started we need to identify the partition containing the Grub folder. (Usually the same as the Linux partition) Say it is (hd2,3) and /dev/sdb4.
(The (hd2,3) must be how grub sees the partition during boot-up)
Open a terminal in Linux and type
- su #(use sudo -i in Ubuntu)
- grub
and at the «grub>»prompt
- device (hd2) /dev/sdb
- device (hd0) /dev/sdb
- root (hd2,3)
- setup (hd0,3)
- quit
Please continue reading at: Common Final Solution
GRUB2 solution (on its own)
As long as I know GRUB2 cannot install itself on its own.
GRUB2 solution (Linux shell)
This installs first part of Grub2 to the first sector of partition containing the Grub folder.
Let’s suppose that you know that your Linux partition is /dev/sda3
What you need to to is run:
Open a terminal in Linux and type
- su #(use sudo -i in Ubuntu)
- grub-install —force /dev/sda3
Please continue reading at: Common Final Solution
Common Final Solution
As a final solution we need somehow Windows to chainload our Linux partition. If we use easybcd we can avoid having to copy a file from a live cd to our Windows partition and setting up the boot. If we are geeks and classical we will have to edit boot.ini or the new Vista file manually in order to make
things work.
Windows Vista (with easybcd help)
- Download and run EasyBCD 1.7.2(or any version i think)
- If program ask for boot drive just select your windows partion
- Choose Add/remove Entries
- At «Add an Entry» select «Linux»
- Change Type to «Linux»
- Enter Name box with any name u want
- At Drive Select Your Ubuntu Partion
- Click «Add Entry»
- Click «Save»
- Restart, you have done ^ ^
Classical Final Solution
Once grub has been installed to a partition we need to get its boot sector to a file in order to boot it from Windows.
Let’s boot with a live cd and open a terminal.
Identify the partition containing the grub folder. (Usually the same one as the Linux partition)
In this example the identified grub partition is sda3.
Plugin your pendrive and open it.
Identify your plugged pendrive associated folder.
In this example:
Pendrive mount point is: /media/disk
From a terminal (Aplications -> System -> Terminal) please run:
- sudo -i | su
(When prompted enter your current user password or your root password in non-sudo systems such as Debian. If you do not know how to type | symbol please only type sudo -i)
- dd if=/dev/sda3 of=/media/disk/linux.bin count=1 bs=512
- sync
- Right Click on your pendrive icon in your desktop and click on umount or extract.
Now let’s boot into Windows.
Plug in your pendrive and copy the linux.bin file into c:\ folder.
Windows XP/Windows 2000/NT/Windows
Now let’s edit boot.ini and add this line at its bottom:
c:\linux.bin="Linux"
Windows Vista (manually)
TODO
Now when rebooting if you boot windows you will get a Windows menu with two options: Windows and the new Linux option which will chainload GRUB.
Finally there is an optional step that it is removing grub so that it chainloads Windows menu in the first place automatically at boot.
Rescatux
This feature is not yet available at the Rescapp program. It is available at the Super Grub Disk included with Rescatux. If you want to have this feature at the Rescapp program please complain at the super grub disk mailing list.
Tecnical explanation
One thing you should know
- These methods only restore GRUB successfully if a stage1,stage2 (and optionally a stage1_5 file) is found. If you have deleted these files the GRUB solution (Linux shell) might help although it might be better to reinstall GRUB from a chroot environment got from a live cd.
If your Linux filesystem has errors GRUB might not be able to find its files even if they are there. So sometimes is advised to try to run the:
fsck -yc /dev/DEV
command as root where DEV is your linux partition device.
fsck -yc /dev/sda3
will fix the third partition from an scsi or sata first disk (Although it might not actually be the first one).
- OpenSolaris GRUB cannot be restored to a partition which this method. You need to boot Linux and then use the install-grub command. See man install-grub for more info.
TIP
If you cannot get to restore grub this way you can always try to boot Linux and then use the Grub Solution (on its own) method or the Grub Solution (Linux shell) method.
