    Accidentally deleted partitions when reinstalling Ubuntu, need help recovering data.

    Hi

    I have a laptop with a 500 GB harddisk. It had a Ubuntu and Windows 7 dualboot but now after a partitioning mistake it only has Ubuntu.

    For Ubuntu I had a root partition, a home partition and a swap partition.
    For Windows I had a main partition and a backup partition for backing up data on the main partition.

    In my home partition I had some encrypted home folders from previous Ubuntu installs.

    I wanted to access the data in these encrypted partitions.

    I followed this webpage https://help.ubuntu.com/community/En...home_directory and I created a new folder called backup in my home partition to copy the data from the encrypted home folders.

    I managed to put all the data from the encrypted home folders into the backup folder.

    I deleted all the encrypted home folders.

    I decided to reinstall Ubuntu and choose not to encrypt the new user's home folder.

    In the installer's partitioning stage it told me Ubuntu and Windows were already on the harddisk and whether to install alongside or erase entire disk and install Ubuntu.

    Without thinking properly I chose to erase entire disk and install Ubuntu.

    I didn't notice my mistake until after I had installed Ubuntu and installed the updates for Ubuntu.

    I followed this webpage: http://www.dedoimedo.com/computers/l...-recovery.html which shows how to use Testdisk to recover deleted data and partitions.

    Analyse only showed my current Linux partitions so I did Deeper Search.

    After Deeper Search finished it gave me a message saying the harddisk is too small and it can't recover some of my data.

    I am not sure what to do after this.

    I have attached screenshots of testdisk during deeper search and after deeper search

    Here is my testdisk.log file

    I am not sure why the second and fourth partition are describing some partitions as centos. I had centos in a virtualbox vm maybe that is why,

    Please help me recover my partitions and data.

    Re: Accidentally deleted partitions when reinstalling Ubuntu, need help recovering da

    If you actually deleted partitions and then placed several GB worth of data over them, then it will be extremely difficult to virtually impossible to recover data. One of the first steps in recovery is not to change things.

    You will probably never get your partitions back, so you should try data recovery only and salvage files, as many as you can.

    Thank you. I used Photorec to recover most of my data.
