Help with recovering deleted drive/partition.

Hey Apple Geeks! I was trying to install Windows 7 in my Macbook Air last night. I was so dumb that I deleted all the partitions and left out the Partitions for BootCamp. So I had to reinstall Mac OS X and now I lost all my files and installed applications. Is there a way to recover those partitions or drives whatever??? I don't have the time machine back up.. Please help me! Thankss in advance!

Water over the bridge. Too late now to recover anything but this should be a good learning experience. Make backups, use Time Machine or one of the cloning software packages: Carbon Copy Cloner or SuperDuper.
