Accidentally pushed auto during Ubuntu install

#1 Post by lan1967 » 22 Oct 2013, 09:16

Hello, everyone!
Sorry for disturbance.
My task was to reinstall ruined Ubuntu using LiveCD.
I used auto partition option with completely erase of data and reinstalling Ubuntu as a logical volume (they promised easier resize).
Hopefully I stopped the tea-party in two-three-four seconds and found all partitions are messed.
Seemingly data were not touched almost but how to use them without partition table.
There were two-three (GPT) partitions for swap, EFI partition, two NTFS partitions with Windows 7, one EXT4 partitions for home of ubuntu, another ETX4 for system of ubuntu. Probably EFI partition is intact as I can choose to boot both Windows 7 although after that it asks for a recover disk.
Hard drive capacity about 500 Gb.
I tried testdisk with deep search to recover lost partitions but it happens non easy to understand.
I wonder if I am still able to recover my work from this mess.
I attach the log of the deep search of test disk, hope this one helps.
Thank you for your attention.

I used deeper search for Intel partition option.
Originally it was EFI GPT partition.

In log it says:

recover_EXT2: "e2fsck -b 7962624 -B 4096 device" may be needed
recover_EXT2: s_block_group_nr=243/1723, s_mnt_count=0/4294967295, s_blocks_per_group=32768, s_inodes_per_group=8192

recover_EXT2: s_blocksize=4096
recover_EXT2: s_blocks_count 5

and so on. Should I use e2fsck or not?
Thank you for your attention.
