using testdisk after problem occurred by partitioning

[nicrnicr]

Thank you very much oshunluvr but I abandoned the idea of adding / and /home; because it seems too complicated to write

mkdir

and

mnt

in the good partitions.
I'm saving everything in order to install again.

[oshunluvr]

Thank you oshunluvr, I would like to add "/" at the sda8 and "/home" at the sda7.

It doesn't really work that way. You can't have two "/" mount points at one time. "/" is the system root mount point. Whatever install you boot to will be "/".

"/home", if it exists as a separate partition is mounted in /etc/fstab to the /home folder.

I assume you have a second install on sda8 and when you boot to it sda7 is /home, but when you boot sda6, /home is a folder and not sda7.

Are you asking to have sda7 mounted at /home when using sda8 and sda6?

If yes, boot to sda6, edit /etc/fstab and add the line:

/dev/sda7 /home ext4 defaults 0 2

then when you reboot sda7 will be /home.

Note that any files currently in /home on sda6 will be hidden and made inaccessible by the mount.

Thank you oshunluvr, I would like to add "/" at the sda8 and "/home" at the sda7.

Yes I've been thinking about installing everything again.

Thank you for viewing and thank you Schwarzer Kater for your suggestion.

I guess the problem is that there is only one / for the first linux partition and no / and no /home for the second linux.
Please, do you know how I can change this?

"/" and "/home" are just mount points for some partition (technically, file systems are mounted not partitions actually)

I'm unclear what you're asking for here. Please be specific like including the partition device names and what you are trying to do.

It seems maybe you are booting into the install on sda6 and wish to access the other partitions - sda7, sda8, sda9

If so, then just make mount points and mount them. For example, open Konsole and type:

cd /mnt
sudo mkdir sda7 sda8 sda9
sudo mount /dev/sda7 /mnt/sda7
sudo mount /dev/sda8 /mnt/sda8
sudo mount /dev/sda9 /mnt/sda9

You now have access to sda7, sda8, sda9.

The error messages you listed usually mean the drive/partition is corrupted. You could try fixes like those Schwarzer Kater suggests, but you may be chasing a rabbit down a very deep hole.

If the partitions are readable/mountable (or at a minimum SDA7), I would very strongly suggest coping off all the data you need to save and then wiping it clean and starting over.

[Schwarzer Kater]

Perhaps a corrupt /boot/vmlinuz on /dev/sda7?
You could try reinstalling the kernel for this partition… And update GRUB there, too.

[nicrnicr]

I also have had to swap

1   P
3   *

with

1   *
3   P

The partitions are now readable.
But sda7 cannot start.
I get the following message:

error: invalid magic number
error: you need to load the kernel first

Thank you very much for viewing.

I've been looking around.
This is clear:

The following partition can't be recovered:
Partition Start End Size in sectors
> HPFS - NTFS 60800 254 63 67405 253 49 106109249

In order to save as much partitions as possible, the only following changes are possible

I've been looking the starts and ends of sectors; I choose the second one; and now I have to restart the computer...

Thank you Schwarzer Kater for your answer,

I beg your pardon.
I wanted to write again

testdisk

in a shell, but the screen asked again

create a log file?

and I've been afraid that it could interfer with the ongoing process.
I now stopped this ongoing process and took screen captures of the testdisks screens:

[Schwarzer Kater]

Which error occured doing what exactly with which program?

"HPFS - NTFS" is not the name or label of the partitions but the partitions' file system type.

[nicrnicr]

Dear All,

I'm using testdisk to repair a HD, which is no longer readable, after having wanted to move the rightest partition to the right, and after an error occurred.
It wrote me that the HD is to small, because there are too many GB and that the problem is concerning the two or three partitions which have the same name HPFS - NTFS.
I have now the window that you see enclosed and I would be happy if you could help to decide what to do.
