Partitions broken and duplicated

Hello everybody,

I started using TestDisk after I broke the dual boot of my laptop (Windows 10 Creators update + Linux Mint 18.2).
After having started TestDisk, I got this:
Test Disk Intel 2.png
Test Disk Intel 2.png (67.6 KiB) Viewed 1391 times
And then after I chose HPFS - NTFS and pressed Enter, I got that (Deep Search 30% completed but still running):
Deep Search 30.png
Deep Search 30.png (53.04 KiB) Viewed 1391 times
I noticed that all partitions are deleted and duplicated as well.

Would you suggest to delete the duplicates?

Thank you all,

William

You are currently looking for lost/deleted partitions. Assuming it's your problem, you will have to use the arrow keys to switch the partitions to keep/recover from D(eleted) to P(rimary), L(ogical) or *(bootable). If the generated partition table is ok, choose Write, confirm, Quit and restart your computer.

Hello Christophe,

I did this operation
you will have to use the arrow keys to switch the partitions to keep/recover from D(eleted) to P(rimary), L(ogical) or *(bootable). If the generated partition table is ok, choose Write, confirm, Quit and restart your computer.
But nothing happens after that, I still have a system failure (I selected HPFS - NTFS as primary bootable).

Since this laptop had Windows 8 preinstalled, then I installed Linux Mint alongside then upgraded from Windows 8 to Windows 10. everything fell apart as soon as I upgraded to Windows 10 Creators update I wonder if this is not a bit more complicated (partitions overlapping)
So first, in order to retrieve Windows 10, I chose Intel instead of EFI GPT.

Then I get this screen with all partitions deleted:

Then I chose the first partition and start a deeper search.
I selected the biggest deleted partition which corresponds to the Windows partition and set it as boot:

Let's see how it goes.

Thanks for your support !!

By the way after I entered the command

Code: Select all

sudo gdisk /dev/sda
, I got these errors:
gdisk GPT 3 errors.png

Really not sure what I am doing...

As your partitions overlaps, copy the files you want to keep/recover on another disk and once it's done, set the partition you want to keep as *(bootable) or P(rimary).
When finished, choose the partition table, and reinstall an OS (Windows or Linux Mint) in the unallocated space.

Hi Christophe,

I gave up with the current broken dual boot, I simply reinstalled Linux Mint in the whole disk and use PhotoRec to recover as many files as I can.

Thank you so much for your help and tools !!
