Mbp boot issues

[jdwagner888]

My computer is missing some boot files so it gets stuck at the startup screen. I can get to disk utility with the boot key combination. My question is, with no other computer available, and no install cd. What can i do to allow my computer to unmount the ssd so i can erase-reformat it to make it compatible to re-install osx.

Care to share any information regarding your hardware and version of OS X you wish to install?

256gb ssd. Any osx will do fine i can always upgrade from there. My main issue is being able to un mount the drive

You'll need to boot into single user or verbose mode and do it through the command line.

That's how to boot in single user

Here's some other info http://support.apple.com/kb/TS2570

From there you'll need to use some google-fu to help you on your quest. Good luck!

You might try internet recovery mode. Command+R at startup.
