MacBook Pro no Boot

Hi! So I'm new to this forum and just need some advice! So I was attempting to dual boot my computer to a Linux machine and OS X however, somewhere in the process the filestystem was corrupted and will no longer boot... to anything... I've tried all of the hot keys at startup and it will not boot into recovery, safe, verbose, or even allow me to pick a startup disk. It's just a blueish/grey screen after the startup chime. All systems are running fine. I hear the fan and I hear the disc run in the drive however I cannot eject the disc... It has a bootable OS on the disc and I still cannot get anything to boot... Any advice?

Edit:

Click to expand...

- What MacBook Pro model is this?
- What Mac OS version is installed?
- What "systems" are we talking about? If all systems were fine...it would boot.
- What disc are you trying to eject? Not sure if you're talking about a hard drive, a USB drive, an optical drive.

My theory. When partitioning the storage for the two partitions...something got messed up. I think booting from an external drive & running Disk Utilty would be a good place to start (at least get it booted up properly).

Take the OS drive out and and see if it gets to the "Live" disc in the optical drive. If it does, and you have an enclosure, you can then erase and format it.
