Cannot recover partition table in Gparted

Please provide partition table.

If you can't boot from hard drive, boot en Ubuntu CD/USB stik and then choose "Try without install".

Open a terminal: you can either press Ctrl+Alt+T or Applications->Accessories->Terminal.

To copy/paste in a terminal, replace Ctrl+C by Ctrl+Shift+C and Ctrl+V by Ctrl+Shift+V (for historical reason, Ctrl+C is assigned another function).

Paste to terminal the following commands:

    sudo fdisk -l

where "-l" is lower case "L".

Copy/paste result into a new thread post.

i'm assuming you installed ubuntu on a different drive. if this is the case, you need to click the box in the top right corner of gparted which said sda1 (if you have ata drive) and select another drive/partition. otherwise, do what delance suggested.

Hi!
Here is my partition table using sudo fdisk -l.

omitting empty partition (5)

I used separate partitions to install ubuntu, not within windows. But I used "Install side by side" options.

Marcus Aurelius's suggestion did not work.

I used separate partitions to install ubuntu, not within windows. But I used "Install side by side" options.

Marcus Aurelius's suggestion did not work.

You have at least two Linux installed, perhaps three (2 swap, and 3 Linux partitions). And a Windows partition in extended partition. It looks like a mess. Do you have data to recover ? What is sda7 ? I think moving sda7 at start of extended partition, and reinstalling Ubuntu will provide a cleaner situation.

What I did actually, I partitioned the unallocated space left for linux using Gparted. There I created swap, /,/home and /boot partitions. Inadvertently during the installation I opted "install side by side" option instead "install using manually partitioning the space". Ubuntu created its own partitions leaving my created partitions aside. Thats why you see two swap partitions etc. Actually there is no other linux in my computer except Ubuntu. SDA7 is a windows partition which was there before installing ubuntu. Later when I reinstalled windows the grub loader deleted and I tried to reinstall it by using the command
sudo mkdir /media/root
sudo mount /dev/sda1 /media/root
sudo grub-install --root-directory=/media/root /dev/sda

Inadvertently I gave sda1 where windows is mounted. Later I corrected the command by giving sda8 where actually linux is installed.
Will it clear my problem ?
How can one move the partition sda7 at start of extended partition ?
Actually I can't see any partition in Gparted !!

Thanks..

I will have a look later. You should raise a bug against Gparted. If fdisk is able to read partition table, Gparted should be able too.

I have found this, but it looks heavy: http://pizzach.blogspot.com/2009/02/moving-ntfs-partition.html
I thought I will be able to do with "parted" but if doesn't list NTFS as a partition he can move.
We can use a trick which sometimes works to fix partition table:
run command
  sudo fdisk
and inside fdisk
  w
which will rewrite partition table. Sometimes, it's enough to fix bugs in partition table and allow Gparted to work.
Could you try and report result.

Followed your suggestion, but sudo fdisk gives the following

kisor@kisor-desktop:~$ sudo fdisk
[sudo] password for kisor:

Usage:
 fdisk [options] <disk> change partition table
 fdisk [options] -l <disk> list partition table(s)
 fdisk -s <partition> give partition size(s) in blocks

Options:
 -b <size> sector size (512, 1024, 2048 or 4096)
 -c switch off DOS-compatible mode
 -h print help
 -u <size> give sizes in sectors instead of cylinders
 -v print version
 -C <number> specify the number of cylinders
 -H <number> specify the number of heads
 -S <number> specify the number of sectors per track

later tried with sudo fdisk w
but did't work.
Did I follow the wrong way to go inside fdisk ?

Thanks,

@ kisor
try
sudo fdisk /dev/sda
then there is an option w - which allows you to rewrite the partition table..
but .. i do not know whether that will make it visible in gparted or not ??

Oh! yes I tried with sudo /dev/sda then opted w. What happened, I lost grub loader again and had to reinstall grub.The situation is as earlier ... Should I format the whole drive and reinstall windows/Linux again ? Thats a tedious job !
So that failed.....

Thanks

Finally I had to format the whole drive and reinstalled windows/ubuntu.... but the way the problem solved is not expected...The source of the problem not detected.
Thanks,...
