    Thinking of adding a 3rd OS


    I am currently running Ubuntu and windows XP on my laptop. I am thinking of adding windows 98 or another kind of linux as well.

    Are these the steps I should follow?
    -Add another partition
    -Add the new OS to grub's list
    -Install the new OS

    Am I close?

    Thanks.

    yes ! you are close.

    create partition and install OS. new OS will install its Boot Loader too (let it install) and detect other installed OS except Fedora Core and Windows.
    for Fedora core, add entries of other OS' in its GRUB and for Windows, re-install GRUB and add an entry of Windows in it. dont create new SWAP partition coz you can share existing.

    Ok, so if I do the partition and install windows 98, I will still be able to boot Ubuntu and XP? And then I have to reinstall grub for it to see windows 98??

    Thanks.

    No ! machine will boot up Windows 98 only coz Window 98 installer will overwrite MBR and remove GRUB.
    re-install Ubuntu GRUB after windows 98 installation and add an enrty of windows 98 in its menu.lst file.

    hmm...

    So I'll only be able to boot win 98? Will I have to use a live cd of Ubuntu to reinstall grub?

    Thanks again.

    yes. boot up through Ubuntu LiveCD after Windows 98 installation and execute this
    Code:
    sudo grub-install /dev/hda
    on reboot, GRUB will show all OS except Windows 98. boot up Ubuntu and add an entry of Windows 98 in its menu.lst file.

    Knowing how to restore the Linux boot loaders and MS MBR is a must if you want multi-boot.

    booting tips

    An multi-boot example can be seen in this link

    Ok I am peeking at my menu.lst file and I see:

    title Ubuntu, kernel 2.6.15-27-386
    root (hd0,2)
    kernel /boot/vmlinuz-2.6.15-27-386 root=/dev/hda3 ro quiet splash
    initrd /boot/initrd.img-2.6.15-27-386
    savedefault
    boot

    title Ubuntu, kernel 2.6.15-27-386 (recovery mode)
    root (hd0,2)
    kernel /boot/vmlinuz-2.6.15-27-386 root=/dev/hda3 ro single
    initrd /boot/initrd.img-2.6.15-27-386
    boot

    [some other versions of ubuntu]

    title Windows XP
    root (hd0,0)
    savedefault
    makeactive
    chainloader +1
    I do not understand the (hd0,0) and (hd0,2).

    When I will need to add one for win 98, what will I use?

    Thanks again.

    I do not understand the (hd0,0) and (hd0,2).
    hd0 --> first harddisk.
    hd1 --> second harddisk and so on...
    hd0, 0 --> first partition of first harddisk. hd0, 2 --> third partition of first harddisk.
    When I will need to add one for win 98, what will I use?
    note down partition number using fdisk command. e.g. if you install Windows in /dev/hda6, its reference ( device code ) will be ( hd0, 5).

    Awesome, thanks!!

    I was confused because i'm used to seeing hda6 meaning hard drive a, partition 1. It's weird seeing hd0, meaning hard drive 1.
