Recover multiboot partition table after Windows Update

#1 Post by meneerpieter » 22 Dec 2017, 07:45

Hello,

I just ran Windows 10's Anniversary Update which has destroyed my partition table (seems like a common problem that I wasn't aware of before running it...)

I had C: for windows, D: for files and a partition for Linux and one EFI partition. Now Linux is gone, D: is gone. Only C: is still there which has none of my important files :|

With Testdisk I can still access my Linux partition so I'm trying to make backups of some of my files (it's extremely slow). What used to be the D: partition is not accessible through Testdisk.

Quick analysis shows this list:

1 P EFI System [EFI system partition]
2 P MS Reserved [Microsoft reserved partition]
2 P MS Reserved [Microsoft reserved partition]
3 P MS Data [Basic data partition] [Windows]
4 P Unknown [Basic data partition]
5 P Unknown [Linux]

I assume P (primary) is incorrect. Can I simply change the partition type or what am I supposed to do here? I'd really appreciate some help.

Thanks

Try Deeper Search if TestDisk hasn't found D:
