Thread: Dual Boot windows 7 and openSuse 11.4

  1. #1

    Default Dual Boot windows 7 and openSuse 11.4

    Hi,

    I am trying to dual boot windows 7 and openSuse. I have shrunk my main partition and it is now unallocated.

    When running the DVD at the disc section I got the message
    Delete partition /dev/sda1 (199.00MB) This is my windows system partition (NTFS)

    Delete windows partion /dev/sda2 (261.49GB) This is my main partition C: (NTFS) (Don't want to delete this
    Resize impossible due to inconsistent fs. Try checking fs under windows.

    Delete windows partition /dev/sda3 (16.31GB)This is my recovery partition.(NTFS) I also don't want to delete this.
    Resize impossible due to inconsistent fs. Try checking fs under windows.

    Delete partition /dev/sda4 (103.34MB) HP tools (FAT32) (Not sure about this, but would rather keep it.


    Create swap volume /dev/sda1 (2.01GB)

    Create root volume /dev/sda2 (20GB with ext4)

    create volume /dev/sda3 (276.08GB for /home)

    I also pressed created partition and clicked on the unallocated space but I got an error telling me that I either didn't have enough space or hadn't selected enough partitions. (The unallocated space was 20GB)

    Thanks for the help,
    Jonathan

    You need to delete one of them.
    I say sda4
    The you can resize sda2 (defrag it first)

    here:

    When you have some space form sda2, create an extended partition in ALL that space and then your Linux partitions inside the extended.

    Indeed
    In which case leave sda4, delete sda3, shrink sda2 and create the extended in the free space, then your Linux partitions in the extended

    I use Parted Magic for this kind of work

    I suggest you put the boot flag on the new extended, take it off any other partitions such as sda1 or sda2

    How much of sda2 261.49GB is free?

    Sorry was busy and still haven't partitioned About 160GB but I was only going to use 20GB for openSuse. Why bootflag?

    Booting is a chain of programs that start in the MBR. Linux does not in general care about a boot flag. It is really only useful if you put generic (ie Windows) boot code into the MBR. Grub boot code in the MBR simply goes to the location of the Linux /boot to start Grub. If you do use a generic MBR then you do need to put the Grub boot code in the partition containing /boot and set a boot flag to it. The boot flag simply tells generic boot code where to go next.

    I'm a little confused. Is this so that I can keep the windows boot loader in case I want to get rid of opensuse?

    Well lots of reasons. Windows is finicky about things and some update may try to rewrite the MBR which if it has Grub code will no longer boot Linux. Note it is not that hard to fix but you do need to understand this stuff. Also you may have more then just 2 OS's so things can get complex. By default the Linux install will load the MBR with Grub which is fine until windows decides to change it. It totally depends on how you plan to setup and use the machine. It does make it a bit simpler to drop Linux if you keep a generic boot code. You just move the boot flag back to Windows erase the Linux partitions and it is gone.
