Inserting a useful "Boot Master" menu.lst sudo grub-install -root-directory=/mnt/boot_master /dev/sda In this case, it's /dev/sda, but of course you should replace this as appropriate.
WINDOWS 10 LOADER STILL DEFAULT CHANGE TO GRUB INSTALL
So, we'll install the grub files using the main HDD device. Now, we want the boot master to be the first boot loader after POST. Installing Legacy Grub files to the boot master.Install Legacy Grub: sudo aptitude install grub.Purge Grub2 from the LiveCD in-memory boot: sudo aptitude purge grub2 grub-pc.If you're booting an older version of Ubuntu Live CD, skip ahead to Step #3. If this Ubuntu Live CD is version 9.10 or greater, it will come with Grub2 by default, so we need to purge it. (4) Configuring the "Master Boot Loader" for the First Time If this is your first time configuring the "master boot" configuration, just leave all boot loader defaults from Linux's perspective.You're installing Linux on the third partition (/dev/sda3).Install your favourite flavour of Linux (Hopefully Ubuntu!).Īgain, going into details on this is out of scope for this tutorial.

It is advised to install Windows first, but when you're finished with this tutorial, the order really doesn't matter, but it is still most efficient.Installing Windows will overwrite any existing boot loaders on the MBR.For this scenario, you're installing windows on the first partition (/dev/sda1).

My assumption here is that if you're reading this, you know how to install Windows. If you're unfamiliar with this process, here are some helpful articles: Mac/Linux/BSD can follow (possibly in logical partitions) Stick the 128MB "Boot Master" partition after Windows as type=ext2.Windows partitions typically need to go first, and must be on a primary partition.Google is your friend if you're new to this. How you'll partition for multi-os is completely dependant on your OSs, how many of them, etc. I like to wedge the "master boot partition" between Windows and LinuxĬonfiguring partitions has been covered extensively already, so I won't re-invent the wheel here. dev/sda4 19645 19929 2289262+ 82 Linux swap / Solarisįirst partition because Windows will cry otherwise To achieve this goal, consider the following basic partitioning scheme: $ sudo fdisk -lĭisk /dev/sda: 163.9 GB, 163928604672 bytesĢ55 heads, 63 sectors/track, 19929 cylinders (!): Please keep in mind through, that this solution scales to any number of operating systems. In other words, a "dual boot" scenario with a concept I call "Master Boot Loader". My actual setup consists of multiple operating systems, and the partitioning scheme is a little complicated, so for this tutorial, I will simply to the following concepts: Multi Boot and the Master Boot Loader - A Simplified Dual Boot Scenario The best thing to do is hide by default the individual OS-coupled boot loader menus because in most cases, they're irrelevant. They can have all of their defaults, including those pesky growing kernel entries. In fact, it allows each of your individual boot loaders per operating system to be completely unaware of any other operating systems if you so choose. How does this affect the other OS-coupled boot loaders?: Not at all. That is to say, our "master boot loader" is decoupled from any individual operating system. Why this "Master Boot Loader" thing?: OS installations can come and go, and if one gets blown away (or dies), we don't want to be stuck without a boot loader, unable to load any other operating systems! The concept of a "master boot loader" allows all operating systems to be bootable regardless of the state of any other operating system. The purpose of this partition is to chainload the boot process to any number of operating systems without relying on any one operating system. (See Step #4, (ii) for additional notes)ĭefine: "Master Boot" - This is the boot loader which is first loaded from the Master Boot Record (MBR). Don't get me wrong, Grub2 is a step in the right direction, but for me (and possibly others), I found Grub2's lack of control frustrating for what I'm accustomed to doing. With the recent introduction of Grub2 into the Ubuntu community, I found it extremely frustrating to do what I had previously been doing with the legacy grub system. I've been meaning to write this tutorial for a long while now.
