Fix formatted GPT in SSD

I accidentally formatted my SSD's GPT while formatting a USB in Linux's gparted. Now, when running gpt in Mac's command line, this is how my SSD looks like:

My-MacBook-Pro:~ user$ sudo gpt -r show disk2
       start        size  index  contents
           0           1         PMBR
           1           1         Pri GPT header
           2          32         Pri GPT table
          34  1000215149         
  1000215183          32         Sec GPT table
  1000215215           1         Sec GPT header

I used to have 2 partitions on this drive: Mac OSX and a Windows 8.1 bootcamp partition. I wouldn't mind loosing the latter.

I have heard about being able to restore the partition with the gpt command in Mac. Is this possible in my case?

Thanks, Martin
