Hi everyone. I have question about hard drive recovery posibility in my problem. I had 1 TB drive with 2 partitions - Macintosh HD(700 gb) and BOOTCAMP(300gb). I had tried to erase my bootcamp partition with Disc Utility (Tried to do it with Boot Camp Assistant but unfortunally). It wasn't erased but replaced with "disc 4" partition with 1 TB free space. Disc utility showed Macintosh HD partition too (with 700 gb like in the past). I restarted my iMac and turned Alt key, but now I have only 1 Windows icon (who can't load due "Operating system is missing" without Macintosh HD on startup. Disc utility under Recovery HD shows only "disc 4" partition fully free (1TB) and there is no Macintosh HD partition now!!! I didn't use backup or Time machine. Please, someone tell in you know, if it possible to recover data from Macintosh HD or I just have lost it at all and do full formatting>set up new Lion OS. Thank you very much and sorry for my bad english here.
