Need to restore id=83 linux partition, after vista deletion

[CountMist]

I deleted my Vista Partition, but it seems like it deleted my entire linux partition along with it. All that is left now is the linux swap. Both the id=83 ootreclinux partition and the ext3 are gone.

I have tried..


sudo grub
find /boot/grub/stage1
Error 15: File not found
I have also tried using Super Grub options
most return the same Error 15

I have also tried booting into a windows CD and used the auto repair and command prompt


Bootrec.exe /FixMbr
it returns successful, but the problem got worse from there. I used to be able to see the Grub Error 22 at startup. Now it just exits intel start up all together.

I have also tried the other Bootrec.exe options( Fixboot, ScanOs...)

And I did not use Wubi, ubuntu 9.04 was installed on a separate partition.

So I want to restore my linux partitions. Any Idea on what I can do?

Restoring a deleted partition by creating an exact size partition is also an option. Any suggestion on that?

Thanks in advance.

Try testdisk. It's pretty good at finding partitions. http://www.cgsecurity.org/wiki/TestDisk

You can install it in a live cd environment (universe repository required).
sudo apt-get install testdisk
sudo testdisk

Once you've recovered your partition, you can reinstall grub. Assuming it's /dev/sda5

sudo mount /dev/sda5 /mnt
sudo grub-install --root-directory=/mnt/ /dev/sda

Thanks. I used TestDisk and it seems to be see my partitions again :).

but i'm getting this error



ubuntu@ubuntu:~$ sudo mount /dev/sda5 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sda5,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

that doesn't sound good. I'd start by running fsck on it. see if that helps.

Before doing that you might want to consider whether there is data on there you don't want to lose. It might be better to make a backup image or attempt to recover the data prior to anything else.

crap....i did this already



ubuntu@ubuntu:~$ sudo e2fsck -f /dev/sda5
e2fsck 1.41.4 (27-Jan-2009)
Superblock has an invalid journal (inode 8).
Clear<y>? yes

*** ext3 journal has been deleted - filesystem is now ext2 only ***

is it too late for me to do



dd if=/dev/sda5 of=/media/disk/backup-sda5.img
I have space on 'disk'

I honestly can't say one way or the other at this point (i.e. I don't know). I'd be inclined to see if it mounts and whether the data is intact. If the data was crucial I might take a more conservative approach.
