A while back I partitioned my hard drive into two equal parts. I completely forgot about it and then realized that I only had half of my original drive space available. I startup disk utility and attempt to shrink the second partition to a much more reasonable 100GB. However, when I tried this I got an error message that read "partition failed error. couldn't modify partition map because file system verification failed." So I do a little research and try to boot in single user mode in order to fix the problem. But when I do i'm met with a screen that looks like this.
