    Problem on dual boot - partition of Fedora can't be found on Ubuntu Home?

    Fedora 17 64bit desktop
    Ubuntu 12.04 64bit desktop

    Ubuntu was installed first taking up the whole HD. Then I installed Fedora by resizing Ubuntu partition making room for its installation. Now I can boot either Fedora or Ubuntu

    On Ubuntu terminal:-
    $ sudo fdisk -l
    Code:
    Disk /dev/sda: 160.0 GB, 160041885696 bytes
    255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x000bfde6

    /dev/sda4       154626048   296331263    70852608   8e  Linux LVM
    /dev/sda5       296333312   312580095     8123392   82  Linux swap / Solaris

    Ubuntu Home can be found on Fedora Home
    see attached Screenshot_f17_home.png
    under Devices
    79 GB V,,,

    Please advise how to detect Fedora partiton on running Ubuntu?

    TIA

    Re: Problem on dual boot - partition of Fedora can't be found on Ubuntu Home?

    As you can see in the fdisk results, Fedora installs as LVM.

    Ubuntu doesn't include LVM by default unless is installed on LVM too. You can try adding the package and activating the LVM and then it should be detected.

    Code:
    sudo apt-get install lvm2
    sudo vgchange -ay
    See if that helps.

    Since you planned to dual boot with Fedora and let it install as LVM you could have installed both OSs as LVM. It would have given you a bit more of flexibility too.

    Thanks for your advice.

    It's separate LV that's why. Notice how it said 3 logical volumes now active, not only 2.

    And in the fdisk results notice lv_swap, lv_home and lv_root.

    The users Home folders are in the 21GB filesystem (that's the lv_home logical volume of 21GB).
