Partition corrupted Windows Xp / Linux Ext4

[FantoMax]

Hi,
My original situation:
Hard disk : 1 Tbyte

1. Primary Partition: 300Gbyte NTFS - Windows XP [WDC_Disco_C]
2. Logical Partition: 200Gbyte NTFS - [WDC_DSK1_VOL2]
3. Swap Linux: 4 Gbyte
4. \root Linux: 40 Gbyte Ext4
5. \home Linux: 456 Gbyte Ext4

With Gparted I reduced the \home partition to 100Gbyte and increased the \root to 80 Gbyte, so at the end of my extended partition I haved around 320Gbyte free space.
Gparted move correctly my partition and at the reboot Windows XP and Linux boot without problem.
My error: with "computer manager\disk manage" of XP I manage the free space to create a new logical partition in NTFS, and this corrupted my Linux partition and also the boot (grub2).
Now I have this situation:

                            Try to locate partition

Now can boot my hard disk but, if possible, I would to rescue my Linux partition.
I ordered a new hard disk to made a Backup so, I can try to rescue the Linux partition.
Someone have a clean solution to solve my problem???

Thanx in advance.

Just a couple of questions:
How do you start the NTFS Recovery Software if Windows does not work?
You would need another computer or you would have to create your own boot Windows CD.
May be something like Bart's Win PE?
My other question would be why the link to buy the software is different than site advertising it and also why the link to the selling site is disabled ?

With the help of a third party tool Kernel for Windows partition recovery software you can easily recover your corrupt and deleted windows partitions from hard disk.

It looks like I did post something in the wrong thread.
I am very sorry about that. Now about the problem with the corrupted parttion.

Might be you could save your XP boot partition using something like Redo-Backup and Recovery:

http://redobackup.org/

Also save all your important files from the other NTFS partition, either from Windows (you said that you can boot Windows) or using TestDisk to copy them. The problem is you will need another disk.
Or you could use the Minitool Partition Wizard:

http://www.partitionwizard.com/download.html
(bottom of the page- Home Edition - Local download)

to copy your XP boot partition and the other NTFS partition holding data. Same problem here: you do need another disk. Once this is done you can swap the disks to check that your XP system will boot.
The recommendation from SUSE Linux use to be that you should run FIXMBR from the Windows installation CD (you have to choose Repair pressing R, not install, when the CD boots). Windows will ask you for the Administrator password.

http://www.microsoft.com/resources/docu ... ixmbr.mspx

That will remove the damaged Grub. Next step remove your new disk with only the XP system. Replace the old disk back in the machine.

Now you can turn your attention to EXT4 partition and its data.

You can try the ideas in this page:

http://linuxexpresso.wordpress.com/2010 ... in-ubuntu/

Or you could use TestDisk to mark the offending partition as D(eleted, rescan the disk and take it from there. It all depends on how valuable the data in the EXT4 partition is to you or how much time and effort you are willing to spend.

Best of luck

The NTFS partion are fine (Primary and logical), so I can fix the MBR and made Active the primary Partition and Windows Start fine.
I normally use UBCD4win from here I can execute Testdisk, but with last UEFI/GPT-Based Hard Drive Partitions it's not good (it's not my case).

@Fantomax, that message was directed to someone that was advertising software to rescue NTFS partitions running from Windows. After I wrote my reply, the message dissapeared. I suspect the moderators removed it.
A similar message popped up later, with a different user name. I understood that your Windows was not the problem.
Only the boot sector, with a damaged Grub2.
In any case if you read in the recent posts by the author of TestDisk, Mr. Grenier, you should be aware that TestDisk does not recover Ext4 partitions.

Best of luck

I jus misquoted Mr. Grenier.
His message is here:

http://forum.cgsecurity.org/phpBB3/file ... t2147.html

What it does not is undelete files from Ext4.

It looks like is not my day.

Finally I rescued my EXT4 partition:
I used DeftLinuwx 7.2 with Testdisk 6.13.
Analyze with Deep Search option, after around 3 1/2 hours I haved this:

Structure: Ok.  Use Up/Down Arrow keys to select partition.
Use Left/Right Arrow keys to CHANGE partition characteristics:
*=Primary bootable  P=Primary  L=Logical  E=Extended  D=Deleted
Keys A: add partition, L: load backup, T: change type,

I set Logical the 3 linux partition and check with the option "list files" If i can see the files and this was OK.
At the end Write the MBR with this configuration and now I have this:

Now I must align the Linux partition.
