Recovering deleted ext4 Ubuntu partitions using TestDisk

Recovering deleted ext4 Ubuntu partitions using TestDisk
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.

Individual screenshot images:
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.
