Seems to me you need to mount the partition.

Kind regards

Hi $u$hil_k$,

Welcome to LQ!!!

If I am getting it correctly you had a 250 GB hdd on which you had Fedora installed. That was installed on a single partition which I can take as default partition scheme you have selected during install. Is that correct? If that is the case the default layout would have been:

Quote:
/dev/sda1 /
/dev/sda2 swap
or something similar.

Thing that I would like to know is how did you create the partition this time? If /dev/sda1 was in use by / then how can you leave it aside while partitioning?

Can you explain in detail the partition layout that you had earlier and the way you created partition this time.

Did you try to mount sda6? That looks like that might be the one. Open a Terminal in Ubuntu and type:
Code:
sudo -s
mkdir /mnt/fedora
mount -t ext2 /dev/sda6 /mnt/fedora
Then you should be able to access the partition from the Filesystem in Ubuntu, as long as it's an ext2 partition. Otherwise, try ext3/ext4.

Or just omit the -t flag ... w/ Linux file-systems mount is pretty good with
guessing what it's dealing with.




P.S.: Sushil, I took the liberty to rename your thread; the title you chose
was pretty pointless.

After looking at the output it appears that the partition that we are looking for is /dev/sda6. You can mount it using:

Code:
sudo mount /dev/sda6 /media
You can create a separate folder as suggested by WarTurkey or you can using either /mnt or /media (as mentioned above)

And I forgot to mention that for parted -l /dev/sda you have to use sudo. So basically it will look like:

Code:
sudo parted -l /dev/sda
But we have the information we were looking for. Try mounting the partition /dev/sda6 and see if that works.

the partion type is Linux(0x83)

0x83 is a code for Linux type partition. That does not tell you anything about the filesystem format. You can find out the filesystem format using parted:

Code:
sudo parted -l /dev/sda

This suggests that what Ubuntu did was repartition your drive, and leave the
last partition w/o a file-system. In other words your Fedora system is no
more, neither is your data...

Now if you want to recover your data you could use DD, that also will increase your skills quite a bit. There is a lot to learn from that!

DD will only enable you to get the data off the hard drive. If the data is *CRUCIAL* to obtain, then I recommend "photorec" and/or "testdisk." Testdisk restores lost partitions (however, if the first 5GB have been overwritten, then the partition will probably be lost), while PhotoRec doesn't even use the filesystem, and searches for fragments of files on the hard drive and attempts to piece them together. Once it finishes, you'll have a whole bunch of file fragments that you're going to have to go through on your own, though.
