i'm going to post here my request for help I've already posted into another forum hoping someone could help me in solving this issue.
I'd like to have some help in recovering data from the Win7 ntfs partition I have configured into my laptop (HP Elitebook 8460p), after installing LM17 xfce 64.
I'll try now to make the long story short.
- Win7 is originally installed into this laptop
- under win7 I previously resized the partition in order to create a free space of around 60gb for installing linux
- I used to work with LM, but this time I tried to install debian testing via netinst
- everything worked fine with debian until it installed grub since it didn't recognize the presence of win7, but I was informed i should have been able to fix it later.
- unfortunately I din't find the correct way to do it so under debian i was only able to boot into linux
- so I decided to go back to LM installing the latest xfce 64 version, hoping it could recover win7 someway automatically, but it didn't since I found there's a problem regarding NTFS signature that is missing
Below I'm coping everything I tried to do up to now, following what I found suggested in internet.
As you can read below I also tried to use the testdisk tool but "Rebuild BS" didn't worked in fixing the issue.
My optimal goal is obviously to have a working dual boot system but I can also be happy with being able to access the ntfs partion so I can save some data i really need to have.
Do you have any idea of what I can do now?
Thanks a lot

Into this situation, the status of both "Boot sector" and "Backup boot sector" is Bad.
Is there a proper way to operate with TestDisk when both of them are bad? till now I've not found anything related to this situation into the TD documentation.
I was also suggested to try and use the tool "Minitool Partition Wizard boot CD" but unfortunately it didn't work to recover the lost win7 partition.
Thanks in advance of any support you can provide me.
