Добавление linux в загрузчик windows

Довольно странно читать, как на вопрос про «ставить Линукс» отвечают примерно «а нафига тебе, ставь через виртуалку».

1. Линукс стоит на основном рабочем лаптопе уже 4 года. В заводскую Винду перезагружаюсь в среднем раз в месяц, чтоб открыть какой-нибудь cad-овский файл. Дистрибутив — Arch, обновляет пакеты постоянно, работает как хорошие часики. Иногда подключаю док-станцию и второй монитор. Нет, не ломался ни разу, драйверы в ручную не ковырял.

2. Не пользуюсь Грабом давно, просто потому что смысла нет. Записываю загрузчик или напрямую через efibootmgr, или же создаю отдельный загрузчик через bootctl (systemd-boot) и записываю там элементы загрузки. Основное отличие — меню выбора никогда не всплывает (все доступные ОС не высвечиваются), загружается всегда запись №1 из UEFI, очередность можно менять там же. Выбрать одноразово можно при загрузке через специальное меню UEFI, которая всплыват по нажатию одной из F кнопок (зависит от производителья МП) примерно в том же промежутке загрузки, когда еще можно открыть основное меню UEFI/BIOS.

When the Linux distribution is installed on the computer along with the Windows, the Grub bootloader is set as the default for booting the operating system on the computer. It allows you to select the operating system which you want to boot on the computer in the first 30 seconds else it will boot the default set operating system.

To add Linux to the bootloader of Windows, we can follow two approaches discussed in this blog.

• Using the EasyBCD
• Changing the Boot Priority Order in UEFI Menu

Let’s get into the first method.

Method 1: How to Add Linux to Windows 10 Bootloader Using EasyBCD?

EasyBCD is the software that can be installed on Windows 7, Windows 8, Windows 10, and Windows 11 to manage the computer’s bootloader. The EasyBCD comes in two different variants:

•  Non-Commercial: limited features, and can be downloaded on the computer without paying a single penny.
• Commercial: Advanced features and charges us $ 39 (at the time of writing this blog).

You can easily download the version of the EasyBCD according to your convenience from the link mentioned. After downloading the “exe” file of the EasyBCD, you can run it to install the EasyBCD.

When EasyBCD is installed, launch the application. You will see the screen:

Now, to add Linux to Windows 10 Bootloader, you have to click the “Add New Entry” in the EasyBCD options:

Under the “Operating System”, choose “Linux/BSD” and fill in all the details below. Then, in the “Portable/External Media”, choose the location where the Linux Distribution has been downloaded. And close the EasyBCD to save the settings and then restart the machine; the following interface will be displayed on the screen:

Note: These options will be available on the “Commercial” version of the EasyBCD.

How to Change the Boot Priority Order in UEFI Menu?

Another option to add Linux to Windows 10 bootloader is changing the priority order in the UEFI menu. Open the UEFI menu after restarting the computer and pressing the F2 key from the keyboard. The common keys to open the UEFI menu in different manufactured laptops are Esc, Delete, F1, F2, F10, F11, or F12. The following interface will appear on the screen:

Click on the “Advanced” option from the left menu of the screen and then click on the “Change Boot Order”:

Then, set the boot priority order using the “Move Up” and “Move Down” options:

And then, click on the “OK” button to save the priority order and close the UEFI menu by saving the changes with the F10 key. Restart the computer, and Ubuntu will be booted by default.

That’s how Linux has been added to the Windows 10 bootloader.

Conclusion

To add Linux to Windows 10 Bootloader, install the “Commercial” version of the EasyBCD or change the boot priority order of the UEFI menu. In this blog, both the mentioned methods have been explained in detail. You should use the Grub bootloader on the dual boot as it is easy and reliable. Else you can also use the methods explained in this blog.

You can easily install Linux using a live disk. But unfortunately, i did not had a pendrive or cd drive when I really needed to install it. Also, softwares like Unetbootin were giving errors and it did not install. So, here is a complete guide to install Linux directly from hard-drive. I already had Windows 7 installed and I added Ubuntu 16.04 for dual boot.

Step 1:
First of all, you need to create atleast a 10 GB partition in your hard-drive. Follow this link to do so. Also give a label to the partition to make the things easier.

Then download two files from the Ubuntu Archive

Click here to know the names of all versions of Ubuntu. Decide your version to download and go to version-updates in the Ubuntu Archive.

For example, to download Ubuntu 16.04, go to xenial-updates in Ubuntu archive. Then go to main folder. Here you will get installer-amd64 (for 64-bit) and installer-i386 (for 32-bit). Select your architecture and then the rest of the path remains the same for both. ie-
/current/images/netboot/ubuntu-installer/amd64(or i386)/
Click on initrd.gz and linux (for 64-bit) or vmlinuz (for 32-bit) to download these files.
Create a new folder and name it boot in the newly created partition. Put these 2 files in the boot folder.

Step 2:
Install EasyBCD from Here. Click on Add new entry and in the Operating System, open NeoGrub tab and click on install.

Step 3:
Restart your computer and choose NeoGrub Bootloader from the available options. Simply write this commands one by one.

grub> root = (hd0,
[Press Tab to list all the volumes available on your primary hard disk. Write 1 instead of 0 if you created partition in second hard-disk]
grub> root = (hd0,n)
[Replace n with the number of the new partition.]
Then type these commands in order

kernel /boot/linux [Note: type vmlinuz instead of linux for 32-bit]
initrd /boot/initrd.gz
boot

Now it will take you to installer (Mouse won`t work. You need to control with keyboard).

Solutions for a few common errors
I faced a few problems while installing.Here is a list for you.

1. Mount Point — When you select your partition while installation, you need to format the partition as Ext4 journaling file system and select the Mount Point as /
   You won`t get such nice GUI but you will know what I mean to say

2. SWAP Partition — It will ask you to create a swap partition for linux. Select No for now. You can create another patition for linux-swap later.

3. Incomplete installation — Firstly, I had created only 6 GB partition for Ubuntu. So the installer crashed during the installation (it had already completed 64%) and then I needed to start from step 1. So, I recommend creating a pertition of atleast 15 GB.

4. Extra Softwares — During installation, it asked me whether I want to install extra softwares or not. It included Blender, GIMP, etc. Skip it for now. The installation of OS requires 5 GB, but installing these softwares were also one of the reasons why the installation crashed before.

5. GNOME Desktop — You want the nice looking Ubuntu UI, then you must include GNOME Desktop during installation of extra softwares. It will ask the type of desktop environment, gdm3 or lightdm. Choose anyone you want. But I recommend lightdm for computers with low RAM as it is faster than gdm3.

6. grub rescue — I formatted the partition where I installed Ubuntu 16.04 32-bit as I wanted to install 64-bit OS. Then on next boot, I got this error of grub rescue. It was not easy for me solve this problem because it now required an installation disk for repair but I didn`t had any. Follow this link to solve your problem.

Although I had given a very long explanation about installation process, I can guarantee that you will be using Ubuntu in just 3 hours if you get no extra errors.

When I create a Windows / Linux dual-boot computer I usually add Windows as an option to my LILO boot menu. That is the easiest way, and works always.

However, I ran into a situation where I could not use LILO as the primary boot loader and I had to look into the Windows7 “boot configuration data” or BCD. Actually it was Windows Vista, not Windows7, which was the first to abandon good old C:\boot.ini and start writing its bootloader configuration into a binary block of data. I wrote this post just to have this procedure available as a reference.

Windows7 contains the command-line program BCDedit which you are supposed to use for editing your Windows boot menu. A total load of crock it is. It will not support any OS that does not boot from the same hard disk that Windows7 is installed to… so I had some issues getting my Slackware added to the Windows boot menu because I had installed it on a second hard disk.

In the end I decided to shrink the Windows partition a little bit and add a small Linux partition where I could install LILO.

Microsoft has added a basic partition manager to Windows7 – something they do more often. If a 3rd party creates an invaluable add-on to provide functionality Microsoft did not include into Windows, then Microsoft will eventually copy its basic functionality into a half-hearted clone. Anyway, the freed-up hard disk space was allocated to a small partition which became Slackware’s “/boot” and I installed LILO to that /boot partition.

Then, just like in the days of Windows NT and “c:\boot.ini”, I extracted the first 512 bytes from the root sector of that /boot partition (in my case, that partition was “/dev/sda3“) and wrote it to a USB stick which I had mounted on “/mnt/hd“:

dd if=/dev/sda3 of=/mnt/hd/linux.bin bs=512 count=1

Rebooted to Windows7 and transfered that 512 byte file called “linux.bin” from the USB stick to the root of the Windows C: drive.

Next, I used BCDedit to add an entry to Windows7’s BCD store. Note that administrative privileges are required to use BCDedit!. What you do is navigate to “Start->All Programs->Accessories“, Right-click on “Command Prompt” and select “Run as administrator“.

In this command window, enter the BCDedit commands. Start by creating an entry for Slackware Linux. I use “Linux” as the label for the boot menu. The actual label you choose is arbitrary of course:

bcdedit /create /d “Linux” /application BOOTSECTOR

BCDedit will return an alphanumeric identifier for this entry. Copy that string into a text file and do not lose it!

In the remainder of this article I will refer to this string as {ID}. You would replace {ID} with the actual identifier as returned by the command you ran. An example of what you can get for an {ID} is {244ebca6-432f-11df-ab86-ce0c22f636af}.

The next step will be to specify which partition holds the copy of the Linux boot loader sector (our “linux.bin” file):

bcdedit /set {ID} device partition=c:

Then specify the actual path to the “linux.bin” file on that C: drive:

bcdedit /set {ID}  path \linux.bin

The Windows boot menu needs an entry for our Slackware Linux OS:

bcdedit /displayorder {ID} /addlast

Usually you won’t see the boot menu at all (after all, it does not contain any other entry than Windows7 itself). In order to allow the user of the computer some reflection time, we add a delay to the menu’s display timeout. Say, the boot menu should remain visible for 30 seconds before booting into the default selection:

bcdedit /timeout 30

That would be all. You can test the new Windows boot menu by rebooting the computer. You should be able to select either Windows7 (default) or Linux to boot into. When you choose “Linux”, you’ll be taken to Slackware’s familiar LILO menu.

If at any time you would have to remove the “Linux” menu option, you can run the following command … provided you wrote the {ID} string down somewhere:

bcdedit /delete {ID}

Have fun, even with Windows,

Eric
