My disk was dos labelled (MBR). So I ‘fdisk’-ed my disk and entered ‘o’ to convert it to GPT and wrote it to the disk. Now all the partitions are gone. I want those back. I care about the data rather than the partitions

Edit 0:

Solution:

  • install testdisk
  • run testdisk
  • choose “Create” log
  • choose target disk. Eg: /dev/sda
  • Choose appropriate partition type. Mine was MBR and I chose “Intel” and select “analyze”
  • Now you’ll see deleted partitions. Giveem appropriate flags like “*” for boot (efi partition) and “P” any other using space or arrow keys and press enter
  • choose “write” and press y on the prompt to write those found partitions to the disk.

Thanks guys for the help

    yeah, you need some help

    🤡

    On serious note, have you by any chance somehow saved the previous start and end values? Like in history of the shell, terminal or even a piece of paper?
    I’ve found out in the past, that if you recreate the partition table as it was, the data will be read fine

    Otherwise, you might need to use RescueCd to try and get the partition borers back. But if you haven’t rebooted since that fateful keypress, first focus on trying to get to what partition borders were printed in the terminal earlier. IMO it will be the fastest and easiest
    Even if you will get those in cylinders and will have to calculate those back to MBs
