OS X mavericks suddenly *boots into OS X utility screen,

i have LOTS of important data on my macintosh hd that was NOT backed up at all (not even time machine).

first of all i really need all this data,I'm a doctor and a lot of really important data is there.

what i did so far is trying fixing the HD via disk utility but not working, i also got a 1TB ex HD and clicked on "new image" on my macintosh hd and cloned it all (320 GB) to the ex HD in read/write option that after several hours was completed now i got a DMG file of my macintosh hd.

i tried opening it from my ex hd on another mac but it said that it can't be mounted.

can someone please help me restore this data somehow? maybe a some sort of way to open this huge DMG file in another comp?

if not maybe in some other way?

i really need your help,

thanks!
