Installing Grub Legacy from Windows as well as Linux is very easy. Here I will install it from Windows. In the above command, I will merge these two files into a new file called grublegacy. See the screenshot below. Note that you can also easily install Grub2 on Windows , use Grub2 instead. Good luck! Post navigation Previous Post Boot netboot.

It is important to do this as root or sudo , else the generated device. For a more detailed tutorial, see bootable disk creation. Hobby operating systems don't have to use real devices when running on virtual machines although it may be, and it usually is faster. Creating bootable GRUB disk image is similar to installing it on USB devices, but here you're working with image itself and partition device at once.
Setup two loop devices. One will be used for writing GRUB and its additional codes to MBR, and the second will be used for mounting filesystem of your operating system.
Format your partition You can simply use [ any supported filesystem ] like ext2 or FAT Note that if you tried to mount your first loop device which doesn't have any offset set, you would be requested to specify filesystem and even if you did it, you wouldn't get the expected result.
Don't forget to flush the filesystem buffers when manipulating with files on mounted disk image. On a Unix-like system, this can be simply done by executing the sync program in your shell. This information might not be applicable to Linux users, who will most probably want to use a loopback device.
This is for developers on OS X, which doesn't have a loopback device and has a finicky image mounter. First, create a blank, raw image with DD, with the required size. Here, I'll make a 80MB image -- sectors of bytes.
The concept is essentially identical. But first. And there it is! You know have a disk. It should be mountable in OS X simply by double clicking or with the mount command. Whatever device you are using, you may want to have a PC partition table and create a partition you format in one of the filesystems supported by GRUB. If you do, be sure to add the following option the grub-install arguments:.
In general, if GRUB 2 happens to fail to do what you want and you suspect that it needs some missing functionality, just try to add a module name you believe has the functionality you need to the --modules argument. That's why we will now set up the other disk to boot GRUB and have a valid structure.
GRUB will boot into its command shell. If your system does boot from hard drive instead, check your BIOS boot drive settings. From the GRUB shell, you can now complete the installation on the boot disk:.
When you boot from the just-created boot floppy, GRUB stage1 is read from the floppy's boot sector. This stage1 "knows" where to find stage2 it was told so during installation , and loads that. The configuration file tells GRUB where to look for the actual kernel image s. You can set it up so it offers you a selection of various different kernels, even allowing you to boot your "real" OS from hard drive after booting GRUB from floppy. In the end, you will probably want to install both GRUB and your own OS kernel on the hard drive , but we'll stick with the floppy solution for now.
GRUB will find, load, and start it. For more details, menu options etc. There is one extra step involved, finding out under which mount point your USB device is located. You may even have to mount it yourself if it is not already mounted. To install use the following steps:.
