Recover deleted partition during Linux installaton

Just recently faced problem with my Dell Vosto 1014 laptop while installing Ubuntu 14.04LTS.

There are 4 drive of 50 Gb each. During installation Ubuntu was supposed to ask before confirming for the partition removal. But no 2nd check before removing partition and portions were removed.

 Recover Deleted Partition:

1> install test disk from terminal.
2> 

  sudo apt-get update

 sudo apt-get install testdisk

3> Go to run option and run testdisk.

4> its a command line interface . there you select create and select which type of partition to recover.

4> just once done reboot the system. You can get your ntfs partitions back to use with data instact.
