Once I was going to resize partitions on my Mac HD from Bootcamp. I changed my mind and was going to quit, but apparently I hit a button, which made every single mac partion dissapear, and windows 7 refused to restart and be reinstalled.

The 1 TB large HD consists of 3 partions, I believe. Since I can't see their actual size (except bootcamp), this is how I recall it.

1. Macintosh HD about 500GB (Somewhere around 700GB according to disk utillity, but 500 according to Finder, and 500GB was all I could access.)
2. Lion Recovery disk
3. Bootcamp 293.36 GB

To fix this I connected my mac via target disk mode to a pc and ran TestDisk. However this is the results:

Since I Don't have 10 reputation I cant post the image showing the testdisk results, so I post a link instead hoping it is ok.

The two mac partitions' sizes are completely wrong, and BOOTCAMP isn't showing.

I tested using disk utilities from the snow leopard dvd. There there is one 293.36 GB Mac OS Extended partition.

Before I had the firewire cable for target disk mode I tried reinstalling windows. Without success I tried again formating BOOTCAMP. Was that a bad thing to do? Could it have overwritten data from Macintosh HD?

Unfortunately I have no backup. I could bring it to some kind of computer repair firm though.
