Disk Management messed up my partition table!!!

Hi all,

I had a nice working multiple booting system on my Mac Book Air with the following partition table:

Partition 1: Primary - HFS - Bootloader (set as active)
Partition 2: Primary - NTFS - Windows 8
Partition 3: Extended partition (rest of my hard disk was this extended partition containing logical partitions as following)
Partition 4: Logical - HFS - Mountain Lion
Partition 5: Logical - EXT4 - Debian
Partition 6: Logical - EXT4 - Ubuntu
Partition 7: Logical - NTFS - DATA
Partition 8: Logical - HFS - Snow Leopard​

Note: Partitions 4-8 are inside Partition 3 (extended).

Now as I had some troubles hibernating Windows 8, after reading that I have to set Windows partition as active, I went ahead and used Disk Management program and set Partition 2 as active (before it was Partition 1 as mentioned above).
And bammm, Partitions 4, 5, 6 and 7 are lost!!!! This is so bad, Microsoft! I just wanted to make a partition active, that's it... and now my other operating systems and more importantly the Data I had on partition 7 is gone!

Can someone please help me? Are there any chances to get the partition table data back? I have another system that has Linux and Mac OSX if that's needed for recovery. Please help.

P.S. The weird thing is that, as a result of this, all extended partitions seem to be affected except the last one (Partition 8) and I can confirm that it boots and I have a functioning Snow Leopard there... but Partitions 4, 5, 6 and 7 are gone like they never existed before! :(

Windows 8 uses GPT. I suspect your system uses MBR partition scheme. I'm not familiar with Mac. You may have better luck on a Mac oriented forum. If you have backups then you may be able to fix the corrupted data once the partition table is restored.. if it can be.

Microsoft had nothing to do with it. You are running a Mac with Debian, Ubuntu & Windows. Any of those three could be the culprit. You would be better to run Ubuntu & Windows inside a Virtual Machine, then as an actual image on your Mac.
