Hi folks, hope I'm posting in the right section. Basically, a few months ago my girlfriends MacBook hard drive failed and I couldn't it boot up. When starting the MacBook I was presented with the recovery screen but I wanted to try retrieve some files for her first first (she had no time machine backup). I've now managed to install OSX on an external hard drive and can boot my girlfriends Macbook from that. After booting from External HD, when I go into Disk Utility, the Macintosh HD along with the External HD are visible but I can't figure out how to check the content of the Macintosh HD or try to recover files and have no idea what I need to do next. Any ideas on how I can view contents of Macintosh HD and copy necessary files is greatly appreciated.
