    partition table problem,

    Hi helpers ,
    I am facing a bizarre problem. I have installed standalone Ubuntu 11.10 on my PC, and was working fine until i decided to install Windows 2008 R2 for testing purpose alongside with Ubuntu.
    Before installing Windows 2008, my partition table was something like this:

    /dev/sda1 primary partition (40 GB mounted on /, on which Ubuntu lies)
    /dev/sda5 (30 GB ext4 , mounted on /home)
    /dev/sda6 (70 GB NTFS, mounted /media/general)
    /dev/sda7 (75 GBNTFS, mounted /media/others)
    /dev/sda8 (80 GBNTFS, mounted /media/videos)

    I wanted to install Windows on /dev/sda7, but as it was not primary partition, i could not. so from windows interface i tried to delete it but it stuck there. so i just restarted the system.( which is causing me all this problem)

    now when i start Ubuntu, screen goes black, and after a brief pause it prints KILLED on top left. (nothing else)
    i selected recovery mode from GRUB menu, it loads some files then stops, saying kernel memroy error, no killable processes.

    i booted form Flash drive with Ubuntu Live, here is the queer result of fdisk -l in terminal

    Warning: omitting partitions after #60.
    They will be deleted if you save this partition table.

    well, I have got no idea how they came into being, ostensibly they look like copies of each other having same data as i had on /dev/sda6 (/media/others)
    and i cant find my data that resided on /dev/sda8 (/media/videos), i dont want to lose all the data i had on that partition, and I have no idea what to do next.

    Help is required desperately.

    Re: partition table problem,

    Well it seems you have more than 60 partitions. But from what's shown they all have the same start/stop which is why they are duplicates? Maybe gparted will show more than 60?

    Re: partition table problem,

    Thanks for reply

    well, gparted shows less actually,, it shows the correct no. of partitions that i had before,, but only /dev/sda5 seems to be functioning ,, others are marked as unallocated

    It seems like the partition table is corrupted,, is there anyway to just fix the partition table? or i have to re-format every thing (which is last thing i would do).

    or any other way to get back my data easily ( lets not talk about data recovery softwares).

    Re: partition table problem,

    From live mode you can scan the disk with Testdisk and see what partitions it finds. If it can recognize them correctly, you can write the partition table.
    http://www.cgsecurity.org/wiki/TestDisk

    And just for future reference, I don't understand the plan to delete sda7 to try and create primary in its place. If its physical location is really between sda6 and sda8 you can't create primary in the middle of your extended partition. Because that would split the extended and only one extended is allowed, not two.

    Thanks darkod, i found about Testdisk later when i decided to finally re-partition and run data recovery afterwards, which i did but could not recover most of it. Thanks anyway.

    And yes, it was futile to delete extended partition at first, I guess i was just curious to see what happens(was not good experience at all).
