    Default Help With Triple Boot Install

    Hi All

    I Currently have Windows 7 and Ubuntu 10.10 on dual boot system,

    But i want to change that

    I want Win 7, openSuse 11.3 and Ubuntu 10.10 on a triple Boot

    I have a 500gb sata hdd.

    The Rough Plan was to 150gb for Win7, 150 for openSuse 11.3 (50gb for / and 100gb for /home) and same again for Ubuntu 10.10 and 50gb for Swap

    Im using entire drive for 3 Operating Systems and Swap.

    I have read a few guides and they all say install win7 then opensuse then ubuntu, and thats fine but none say anything about partitioning.

    And one main problem is cant split into more than 4 different partitions

    So any and all input would be great help.

    Thank you in advanced

    So, you might want to run Ubuntu and open up a terminal and run the following command if possible:

    Code:
    su -
    password:
    fdisk -l
    And then post the results. Ubuntu uses Grub 2 and openSUSE uses grub. I would want to know which partition is booting now. I would create a LiveCD with GNOME that had GPARTED on it, for use to change the booting partition after you install openSUSE. I might install openSUSE to a new partition, and set it as the boot one, not messing with Ubuntu and loading Grub into the openSUSE partition (instead of the MBR, but must be partitions 1, 2, 3, or 4 only). Once you got openSUSE working, boot from LiveCD and change the active partition for booting back to Ubuntu. Then in Ubuntu, run the command update-grub which is said to add in the openSUSE load command. Here are some threads about using Ubuntu and openSUSE together:

    Hi,

    just to add to what jdmsdaniels3 stated, you CAN have more than 4 partitions.

    What you can't have is more than 4 ** primary** partitions.

    You can however, for example, have 3 primary ones, and one extended partition, within which you can create many more "partitions" .

    Hi James,
    This is not possible since Ubuntu doesn't have a root user by default. You'll have to use sudo or create a root user (Many Ubuntu users wonder how but I promised the moderators on Ubuntu IRC channels not to explain it anymore... well this is openSUSE forum .. maybe I'll explain then ... )

    No problem at all. You can install any Linux in all logical partitions. In both setups, while installing openSUSE and Ubuntu, you should select the method which says "Create partition setup" under openSUSE or "Custom partitioning" or something like that under Unbuntu. This is the "expert" method. It let you select the partitions you want to use rather than making decisions for you. This is the *ONLY* safe and efficient method to install several distros in parallel.

    The order is correct: Windows, openSUSE, Ubuntu. If you would install openSUSE after Ubuntu and don't pay extra care, openSUSE's setup program (YaST) would overwrite Ubuntu's Grub in MBR with a generic bootcode (This is a bad practice IMO). See the pictures I posted here: (net-)installation on a multi-boot system: MBR overwrite
