    Partition table not detected while attempting installation

    Hi,

    I currently use gutsy, and want to do a fresh hardy install.

    I tried a hardy, gutsy, and an intrepid cd, but none of the installers detect my existing partition table.



    Here's fdisk output

    Code:
    ubuntu@ubuntu:~$ sudo fdisk -l

    Partition table entries are not in disk order
    sda6 is my gusty root partition
    sda7 is my home partition
    sda5 is a Dell MediaDirect thing.
    sda1 seems to be the exact same thing.
    sda3 seems to be windows vista
    sda2 is a recovery partition
    sda4: I have no idea what this is.

    Here's a thread which seems to describe the same issue:

    http://ubuntuforums.org/showthread.php?t=780113

    The answer given is 'use testdisk', but there is no instruction on what to do with it.

    Here's what I tried:

    Code:
    TestDisk 6.8, Data Recovery Utility, August 2007
    Christophe GRENIER <grenier@cgsecurity.org>
    http://www.cgsecurity.org
    
    
    TestDisk is a data recovery designed to help recover lost partitions
    and/or make non-booting disks bootable again when these symptoms
    are caused by faulty software, certain types of viruses or human error.
    It can also be used to repair some filesystem errors.
    
    Information gathered during TestDisk use can be recorded for later
    review. If you choose to create the text file, testdisk.log , it
    will contain TestDisk options, technical information and various
    outputs; including any folder/file names TestDisk was used to find and
    list onscreen.
    
    Use arrow keys to select, then press Enter key:
    [ Create ]  Create a new log file
    [ Append ]  Append information to log file
    [ No Log ]  Don't record anything
    Click create

    Code:
    TestDisk 6.8, Data Recovery Utility, August 2007
    Christophe GRENIER <grenier@cgsecurity.org>
    http://www.cgsecurity.org
    
      TestDisk is free software, and
    comes with ABSOLUTELY NO WARRANTY.
    
    Select a media (use Arrow keys, then press Enter):
    Disk /dev/sda - 120 GB / 111 GiB
    
    
    
    
    
    
    
    
    
    [Proceed ]  [  Quit  ]
    
    Note: Disk capacity must be correctly detected for a successful recovery.
    If a disk listed above has incorrect size, check HD jumper settings, BIOS
    detection, and install the latest OS patches and disk drivers.
    Click proceed

    ...
    Select intel (Don't know if that's right)
    Select analyse

    Don't know what to do now. Is that message

    Space conflict between the following two partitions
    important? I selected proceed, and got this:

    Any advice?
