PARTUUID what's that? system can't see partitions

[gnomek]

I need to recover partitions sd5 and sda6



What looks bad is that gparted see those partitions as clean with no data.

I recovered system with clonezilla and now systemcan't see those two partitions

sda5 is /home
sda6 important data

sdb is disk I use to write from

in gparted gparted to:

This happend after I used in Clonezilla advance option "Reinstall grub on target harddisk boot sector".
I don't know what PARTUUID is and how to use it. In fastab I used UUID's.

I read this article
http://askubuntu.com/questions/84501...untu-boot-from

sudo gdisk /dev/sda
GPT fdisk (gdisk) version 0.8.8

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: not present


***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format
in memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by
typing 'q' if you don't want to convert your MBR partitions

Command (? for help):

I don't remember if I used GPT or MBR before. It is SSD disk.


I may loose system but I want to recover those two partitions. I don't know how to use testdisk properly. I don't want to make things worse.

Edit:

When I am here and there is menu

Structure: Ok. Use Up/Down Arrow keys to select partition.
Use Left/Right Arrow keys to CHANGE partition characteristics:

Keys A: add partition, L: load backup, T: change type, P: list files,
Enter: to continue
ext4 blocksize=4096 Large file Sparse superblock, 11 GB / 11 GiB

and I chose positions 29298688 and 64483328 and press P it shows me files and folders on this partition so they are not lost but I don't know how to recover this partition.

Will pressing A recover this partition and write it to MBR?

Edit,
I pressed Enter and there are options for saving partitions.

For now, I wouldn't be concerned about PARTUUID.
PARTUUID, for partitions; UUID mainly for filesystems. Persistent naming methods.

See, also Wikipedia article of GPT partitions.

From your edit, sounds like you made progress. The "OK" you found is a good sign. I think it would warn you if it wasn't ready for a "Write or Save partition." Been since 2009 that I used TestDisk, I'll look at it for an experiment I'm working on--the site, though dated, does have many work-through examples of the "back-and-forth" it takes to get to the bottom of things until you finally do a write/save. Keep us posted. If you can't boot into the repaired partitions, you may have fix the bootloader (maybe Boot Repair disk? re-install GRUB 2? ) and/or use a live CD to rescue your data. Also if they do get restored, check that your fstab is OK.

Thank you. Enter was the right choice. It recovered partitions. I also reinstalled Grub2 from LiveCD and kernel.
Problem solved.

Very nice! Good work! I'm sure glad you got it ;-)
(I was motivated to look at TestDisk, got the latest 7.0, did some experiments yesterday, it works well to recover partitions from either MBR or GPT disks.)
