    Re: How to multiboot?

    There are several things to consider beefore you start your multi-boot installations.

    Your drive is limited to 4 primary partitions. You will need to add an "extended" partition. This is a type of primary partition that you can install, in theory, and infinite number of "logical partitions". Plan this on paper before you start.

    I would make all your partitions before starting installation using gparted from your 9.10 Live CD.

    Fedora and Suse will install nicely with MS but will try to take over any Linux partitions. Make sure you check every partition in their installers to make sure only the partition(s) you want them installed on are marked for use and the others marked as "do not use".

    Grub on your last (Ubuntu) installation should pick up your other OS'. There may be way too many generated entries however. You will probably need a custom menu for this to really work. This is not hard to set up and requires little or no upkeep when finished.

    See the link in my sig for a basic over view of Grub. The second link that I give in that post is the very best in depth study of Grub you will find.

    You need to know this stuff if you are going to multi boot.

    It is a lot of FUN. I am on a drive, right now with 12 installed and working OS' all booted from grub1.98 (from 10.04-testing).

    I am not sure what you mean by that. If you mean can you have more than on Ubuntu the answer is yes.

    I have, right now, seven variations of 10.04 on this drive (test platform), one 8.04, one Mandriva2009-1 and 2 variations of 9.10.

    As long as you are using an extended partition the only real limit is the size of your drive(s) and the amount of space you want each OS to have.

    Exclamation Re: How to multiboot?

    i put in open suse on the primary partition and then fedora on a logical, i got this error message
    no bootable device found - insert boot disk and press enter

    i thought putting in ubuntu karmic and the grub2 will detect everything and sort the issue out , but even then i had the same error, so i put in lucid beta 2 and still the same error
    now in a live cd session and tried running sudo update-grub, but this is the error i get
    "grub-probe: error: cannot find a device for /. "

    here is the output of my sudo fdisk -l:

    this is the order i installed them in.
    Please help me boot !!!


    P.S: there was a install bootloader option ticked by default during fedora installation and i just went ahead with it. is it the cause of this problem??? just wanted to let you know about it...

    Re: How to multiboot?

    I have been off line most of the day (problem with ISP server downtown).

    There is no need to update grub in Fedora. Fedora is just a bugger. To boot to it you will probably need a custom menu entry for it.

    I think there may be a working one in;

    http://ubuntuforums.org/showthread.php?t=1195275

    I have an install of Mandriva on here and os-prober now almost gets it right but not quite. The custom entry does the job with no problem. It is in the first post on the link in my sig.

    Re: How to multiboot?

    If you have grub2 as the standard in one of your partitions you just have to reinstall it like you would after a window boot loader overwrites it. Distributions with old grub can have grub installed to the partition and chainbooting will work but that becomes a custom entry.
