This is a Windows startup error. The Mac must be trying to boot to a broken Windows partition.Hold the power button until the Mac powers off.Then power on and hold the Option key.
When you see Macintosh HD click it to boot to Mac OS X.

If you hold the Option key you should see the Macintosh HD partition, if not please let me know.
If holding the option key doesn't bring up the startup manager, try resetting PRAM first, then booting with Option.To reset PRAM, power on and hold Command + Option + P + R, and wait for the second startup chime before releasing.
