From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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

MBR can be converted to GPT. gdisk can do it, in fact if you run it for an MBR structured disk it will automatically do the conversion in memory, and you can check the results before writing it out. windows also has a tool for that.

Oh yeah i figured there were some tools able to do that, i meant to say that you can't substitute one with the other in place without doing some sort of conversion.
