Question

How do I write (recover) found partitions from [None] None partition media table type (unallocated space?) in TestDisk?

Problem

I changed grub settings (default entry to boot into from 0 to 4), then run the command sudo update-grub. I rebooted my computer. It bypassed the grub menu automatically and entered the "Acer Recovery Manager" (for Windows 7). I canceled it because I did not want to recovery Windows 7. I rebooted the computer again. This time I encountered:

error: no such partition.
grub rescue>

I booted into Ubuntu 12.10 live and run "GParted Partition Editor".

Instead of unallocated space, I used to have / and /home ext4 Ubuntu partitions. I think the "Acer Recovery Manager" deleted (hide) them even though I canceled the process.

Recovering missing partitions using TestDisk

  • Image 7: This partition table is not the correct (desired) table (not the one I want).

  • Image 10: So far, I did not find the missing partitions (above). I did not do deep search yet. I continued the search in [None] None partitioned media table type (below).

  • Image 15: This is the correct (desired) partition table I want. The two ext4 partitions that is now converted into unallocated space. I want to recover these two.

  • Image 16: I found the missing / ext4 Ubuntu partition (above).

  • Image 19: I found the missing /home ext4 Ubuntu partition (above).

  • Image 21: I found the missing / and /home ext4 Ubuntu partitions but since I am in [None] None partitioned media table type, I can not write (recover) the partitions (no option to write).

Updates:

  • Image 24: I found the same /home in the deep search also (above). The deep search was done while I was still in [None] None partitioned media table type, maybe this is why I can't write or recover.

  • Image 28: I found the same / in the deep search also (above). The deep search was done while I was still in [None] None partitioned media table type, maybe this is why I can't write or recover.

Conclusion

How can I recover these two partitions that are found in [None] None partitioned media table type (unallocated space?) and also in deep search?

I have searched around and have not found anything that refers to recovering found partitions in [None] None partitioned media table type.

Updates:

I did not run the deep search while in [Intel] but I did run the deep search in [None] (which I thought was the same). The results are in images 24 and up (hundreds of results was listed from which I found my partitions by comparing the numbers with that of quick search results in [None] (image 15). But I was not able to write anything. So I found the numbers (start, ending, and size) which would be useful in advanced or manual recovery but I do not know how to use them.

At the end, I just recovered some of the data from the partitions and re installed ubuntu. I wanted to recover the partitions because I did not want to install applications, modify settings, and add accounts over again.

This question is closed from my side.

Did you try with partition table type [Intel] and deep search? To recover (=write) testdisk needs to know what partition type to generate. Note that if you have a spare drive at hand you may also try to recover from a drive image to not put your data at risk. –  Takkat Nov 13 '12 at 21:17
