I am trying to make a kernel in Visual C++ (Windows) using the tutorial here. What I am wondering is how to install GRUB from within Windows 7. If I have to download Puppy Linux or something I will, but I would prefer to install it from within Windows. In case you were wondering, I want to boot a PE EXE with a multiboot header that supports GRUB.

EasyBCD can automatically install a GRUB-based bootloader called NeoGrub. It'll be chainloaded from the Windows bootloader, and you can edit its configuration file from within Windows; it also supports NTFS so you can save the kernel to the NTFS partition and load it from there.

Disclosure: I wrote EasyBCD.

Fails on Vista. Fails to install the .Net framework 2. Guess it's time for it to change the framework. Anyways great work. – Nagaraj Tantri Nov 17 '13 at 4:43

The latest version of EasyBCD can use either .NET 2.0 or .NET 4.0. You cannot manually install .NET 2.0 on Vista because it already ships with it. – Mahmoud Al-Qudsi Nov 17 '13 at 18:22
    
I have a peculiar problem : I am able to get to grub rescue, using yours as well as a manual approach, but unable to generate a grub2.cfg from even the rescue disk (some error about not finding /etc/release) – Milind R Nov 18 '14 at 7:36

Crackin' answer... "I wrote EasyBCD"... Boom. – Big Chris Dec 8 '15 at 17:13

Another solution is Grub4DOS.

Despite the name it even works with Windows (XP) - propably with 7, too.

do you have a tutorial to make it work on win 7 ? it does not show up partitions in the UI when i choose Install grub form the menu. – tgkprog Jun 8 '13 at 8:56
    
tried to run WinGrub from admin prompt that did not help either. i have ntfs on my main c drive – tgkprog Jun 8 '13 at 10:06
    
can it find grub.cfg which is in a linux file format such as ext4 ? I think no. – Don Jul 26 '14 at 2:17
    
@Don I did install grub4dos on a fat partition. That can be read and written by all systems. – Nils Jul 26 '14 at 21:04

I had this problem: had Kubuntu installed, then installed Windows 7 (Pro x64), then Kubuntu disappeared from the boot menu.

My Solution:

Install EasyBCD, add GRUB2 to boot menu, reboot, enter *Ubuntu, do this:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

Run Boot Repair.

Choose Recommended repair.

Than again boot Windows and, using EasyBCD, remove GRUB2.

Thanks for reply, I edited it. – notgiorgi Dec 9 '15 at 7:25
    
I'm curious why you remove GRUB2 as the last step. Isn't adding it the objective? – fixer1234 Dec 9 '15 at 14:01
    
If you don't remove it from EasyBCD, when you choose windows 7 on GRUB, then you'll have choice between ubuntu and windows again. – notgiorgi Dec 10 '15 at 11:19

You remove GRUB that Windows created, not the one you created from Ubuntu, or else you'll have two GRUB-s – notgiorgi Dec 10 '15 at 17:43

Another solution is to use Grub2Win that supports both EFI and BIOS loading on Windows 7-10/XP/Vista. Based on grub version 2.02 and give you a GUI to handle a boot.
