    Ubuntu 13.10 win8 partitoin problem

    Hello,

    Yesterday i tried to install ubuntu 13.10. On my laptop was windwos 8 pre installed. During the installation ubuntu couldn't detect the partitions of my hard drive. So I tried to restart again without ubuntu. This time my pc can not detect any partions andf system any more. I can only boot via usb.
    I think there exist a problem with the partition table.

    I have a : Lenovo U430 Touch

    Had someone the same trouble like me, or can help me?

    It's possible that something went wrong with the boot sector. Have you looked at:
    http://www.troubleshooters.com/linux/grub/grub.htm
    I found this on some advice: "It's possible that your Linux system installed its boot loader (GRUB, LILO, etc.) in the Master Boot Record (MBR) instead of the partition boot record (PBR)."

    Re: Ubuntu 13.10 win8 partitoin problem

    When you start the live CD open up gparted, are you unable to see the patitions from here also?

    The next thing to try is to open a terminal and send the output of
    Code:
    ls -al /dev/disk/by-id
    and post the output

    Re: Ubuntu 13.10 win8 partitoin problem

    OK so you have a 1TB HDD (by the looks) which is

    This is split into 3 partitions.

    sda1 : 487 GB
    sda2 : 457 gb
    sda3 : 7.73

    The reason that you don't 'see' anything is because they haven't yet been allocated ~ they have no file systems on them.

    When you initially did your attempt to install ubuntu did you intend to wipe out the windows partition? If so there are no problems,

    Either way you will then probably want to make some logical partitions of this disk (currently this is what sda1,2 and 3 are), you could just give sda2 and sda3 a file system type and you should then be good to put ubuntu (or any other os) onto them.

    What do you want / need to acheive?

    Re: Ubuntu 13.10 win8 partitoin problem

    no thats wrong. i only have a 500GB Harddisk.
    There should exist 3 or 4 partitoins which are NTFS and FAT32 formated.
    But now i can't find them.
    They didn't still exist now.

    The UEFI Bios also don't find any partitoin.

    I think the partition table is damaged or MBR or something like that.
    Can i recover it?

    Re: Ubuntu 13.10 win8 partitoin problem

    Hopefully we should be able to recover from this.

    At the moment it is essential that you do not write anything to the hard drive to minimise the risk of any more data corruption.
    It is safe to continue using your Live USB.

    Firstly before any suggestions for fixing this we need a Boot-info Report. Go here and follow the instructions given to get the the URL for the report and post that here.
    https://help.ubuntu.com/community/Boot-Info

    Do not attempt any repairs.

    They will only complicate matters.

    That is the one; reposted as a link http://paste.ubuntu.com/6218043/

    IMHO there is hope for this using testdisk.

    Using your Live Ubuntu open a terminal type in
    Code:
    sudo apt-get install testdisk
    and hit Enter.

    If the terminal returns with something like 'cannot find testdisk' then do this part: Open Software Centre, go to Edit > Software Sources.
    In this window check the top 4 options close out and close SC. Back to the terminal and
    Code:
    sudo apt-get update
    sudo apt-get install testdisk
    When testdisk has installed you are nearly good to go.

    Spend some time here http://www.cgsecurity.org/wiki/TestDisk to familiarise yourself with testdisk and here http://www.cgsecurity.org/wiki/Running_TestDisk a menu by menu guide.
    This might be more helpful. http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step

    When you get to the Partition-table type selection please take the GPT option.
    After a quick search you will then need to select the 'Deeper Search' to find the erased partitions.

    On a 500GB drive the search will take approximately 2 hours.

    Anything you are unsure of stop and ask for guidance, if possible post screen shots of where you are stuck.

    Good Luck
