How can i repair/recover my partition?

[superspatial]

I have a late 2010 MacBook Air. I was running Windows from an external drive on it and I have erased some unused partitions from my MacBook drive. After restart I notice that my primary partition on mac is no longer mounted and somehow has been transformed from HSF to ExFAT. Does anybody know a method to recover my partition or recover the data from it? I also have 50gb of unallocated space that might be use to install windows but I don't know how to create a mbr partition from terminal for Windows. I've attached some pics with the current partition scheme. Thank you.

How to attach an image to your MR post.​

Maybe gParted Live CD can help, as hopefully only the partition table is corrupt. Why did you use Windows in the first place to modify partitions on the MBA?

All I wanted is to erase some unused partitions but I was very tired and completely forgotten about the partition scheme. So at this point I have only a unmonted partition and the terminal from the Lion Recovery Drive.

This is what Gparted Live says:

Fixed with TestDisk from GParted Live USB and some commands from http://geexhq.com/recover-partition-table/
