I have Windows 7 on a Bootcamp partition, and ended up running out of space; so I figured I'd us Gparted to resize the partitions. When I booted GParted off of my disk drive, it wouldn't even let me resize my OSX partition because it didn't recognize the file format...so I shut down and attempted to log into OSX, only to get the prohibitory sign. I had to use the disk repair utility when I booted into Windows. I attempted to start OSX in safe mode, but it didn't work. This is my first Mac computer, and I just bought it a couple weeks ago (new 27") SOMEONE PLEASE HELP!
