    Question How to multiboot?

    i am desperately looking for a how to : multiboot. Checked bodhi.zazen's thread, but its totally with reference to GRUB Legacy. I have karmic installed and also vista. wondering if there is a step-wise guide to multiboot with reference to Grub2.

    I want to add a SUSE, Fedora and Lubuntu, but have no clue as to how. I messed up my comp earlier trying to multiboot so now I just dual-boot Windows Vista and Karmic Koala.

    I don't know of a step-by-step procedure on how to multiboot with grub2

    What you need to do though, is add the other OSs you wish to multiboot with to the grub menus.

    There are sections in the wiki on how to add other OSs to the grub menus

    Re: How to multiboot?

    So I just install the other OS's and put their entries in the grub and that's it????? But won't every OS that I install try to install their own Grub and what not?

    Re: How to multiboot?

    You have two alternatives :

    1. I'm not sure how other distros handle this - but in ubuntu you can choose to not install a boot loader (e.g grub) - so things like this don't happen. I assume there is such a possibility with other distributions. Then once the other distros are installed - you can just add them to the grub menu

    2. you can install everything - and just add ubuntu last. It will autodetect the rest of the OSs and will add them automatically to grub (overriding their installation of grub if installed).

    EDIT
    A warning though - if you choose to install several distros - you must remember to never accept grub updates from any of them except the one you chose to install grub with... otherwise it might cause some mess..

    Re: How to multiboot?

    Grub or grub2 is just the boot loader. You need to plan you partitions and which boot loader is in charge and how to boot the other systems. Grub2 is very good at finding other systems but if you have a lot the menu becomes very large and difficult to manage.

    I always like chainbooting since each system has its boot loader in its partition and is updated with new kernels so you can easily boot the latest updates. Grub2 does not like to be installed in the PBR so it should not be used for chainbooting but can be. Other systems still using grub legacy can easily be chainbooted. Note separate data partiion.
    Example with old grub booting 145 systems on 2 drives:
    chainboot 145 systems

    http://www.troubleshooters.com/linux...bpartition.htm

    You also have to plan how you handle data. You should not share /boot nor /home as differences between versions can cause conflicts. If you share /home with different user names you have not shared any settings just the partition. But you can share all your data with just a little partition planning. I like having the same firefox, thunderbird and all data in each system.

    Continued to work with Firefox upgrades but I have not upgraded Thunderbird yet, and now have NTFS shared partition:

    If you boot both windows and Ubuntu often you can have the same firefox and thunderbird data in a common partition.
    I created a FAT32 partition (before NTFS linux driver wrote reliably) 2-3 years ago and moved both firefox and thunderbird to the shared partition. I then edited the profiles in windows and linux to look the the common partition rather than the local one. It still worked even when I converted from Firefox version 2 to 3 on both windows & ubuntu.

    * (SeaMonkey) ./seamonkey -profilemanager
    * (Thunderbird) ./thunderbird -profilemanager
